This paper, in order to study the structural features of embodied carbon network in China's multiple regions, uses environmental expansion input-output model to establish China's multiregional embodied carbon network, and applies structural path betweenness centrality to determine the key carbon dioxide transmission sectors in the embodied carbon network,identifying critical carbon dioxide transmission pathways using structural path analysis method,and in-depth research was conducted on China's multi-regional embodied carbon network based on data such as the 2017 multi-regional input-output table.Among China's multi-region embodied carbon network in 2017, the top 30 provincial industrial sectors in transmission embodied carbon include 10 metallic smelting and processing, and 8 electricity and thermal production and processing industrial sectors, who heavily use highly-energy-consuming products from the upper stream industrial sectors as middle input, leading to vast quantity of carbon dioxide transmitted to the down-stream industrial sectors. The top 3 provinces in the betweenness centrality of China's multi-regional embodied carbon network in 2017 are Jiangsu, Shandong and Henan. In the supply chain of embodied carbon transmission in various provinces, the key transmission path for embodied carbon transmission in most provinces of China is the non-metallic mineral products industry → construction industry, power and heat production and processing industry → construction industry, power and heat production and processing industry → other service industries. Some embodied carbon key transmission sectors can not be recognized by using the traditional methods based on production and consumption ends, which can be reached through structural path betweenness centrality. 

Alerting resources environmental carrying capacity helps directly diagnose the status of resources environmental carrying capacity during industrial development, timely make and adjust approaches to industrial development and realize sustainable development. This paper, based on Hainan's 12 key industries, uses alerting technology to set up alerting methods of resources environmental carrying capacity of key industries. In Hainan province, such alerting of tropical agriculture of environmental carrying capacity mainly happens in Wenchang city and Qionghai city, alerting of water resources in the northwest, altering of industries in oceanic oil-gas concentrating Yangpu economic zone. Severe and moderate alerting is in medicine and oceanic oil-gas industrial layout. Local altering happens in tourism and services industries chiefly due to the demands of population over the infrastructures. This paper presents differentiated development and control measurements for key industries of different alerting in different regions, in order to reach a sustainable development under resources environmental carrying capacity.

This paper, based on China's land supply data from 2010 to 2018 gained from China Land Market website via Python program, uses spatial distribution center, regional Gini coefficient, cold-hot spot and panel data model to discuss the temporal-spatial evolution and mechanism industrial land supply in Yangtze river economic zone during bi-transitional periods of market and development and supply side reform, aiming at providing theoretical supports for optimizing industrial planning and promoting supply side reform. Supply of industrial land in Yangtze river economic zone shows a fluctuated decreasing trend with rising, falling and slowly increasing stages. Spatial distribution of industrial land citywide generally tends to be balanced with a shrinking regional land supply difference. Industrial land is the largest in the middle stream of Yangtze river with its distributing center migrating to Yangtze river delta. Land supply is influenced by industrial land price and economic level; it is promoted by increment of fixed asset investment, local financial income and gross industrial production.

Initial allocation of stream water discharge right is a key factor in water right exchange mechanism, and a basis in promoting a fair water discharge and sustainable development. This paper, based on the research advances on rare resources allocation, presents an initial allocation model of water discharge right based on chaos optimization-projection pursuit by means of initial allocation methods of water right and waste water discharge right. Projection pursuit can avoid subjective evaluation, sample-driven optimization is more objective. Initial allocation proportion of water discharge right is finally determined through chaos optimization which is used to calculate the premium projection. Case study on Jiangsu section of Huaihe stream validates this method feasible, which covers historical loss, economic development and ecological environment that plays a leading role. The initial allocation proportion of central Jiangsu in Huaihe stream is generally higher than northern Jiangsu.

This paper, based on remote sensing data of every four years from 1996 to 2016, uses visual interpretation to extract construction land use information, applies constructed area expansion index, dynamic degree, flexibility coefficient and rate to quantitatively analyze its temporal changes during 1996 to 2016 in Karamay city, and studies its spatial differentiation via fractional dimension, barycenter transfer and compactness. Constructed area expands in forms of “clots, inner filling, star-like and along transportation lines”, varying with stages. Expansion direction changes from southeast, southwest to northeast with barycenter transfer consistent with “three-axis-two-district”. Population size drives such expansion with economic development as its core pushing force. Mineral resources development and modern transportation are vital factors, directed by governmental macroscopic policies, which determine the size and layout of urbanization. Issues such as loose and primitive constructed expansion need to be resolved through spatial extensive controls in order to reach a quality growth.

Hebei province lacks water resource, about 1/11 of water resource per capita in China, resulting in a rising conflict between water shortage and economic growth. This paper, based on VAR model and Hebei's gross water use, industrial waste use, agricultural water use, GDP, agricultural added values and industrial added values during 2000-2015, uses stability test, co-integration test, Grander causality, pulse response and variance decomposition to analyze the interaction between water resource use and economic growth in Hebei province, with results showing a co\|integration between economic growth and gross water use, agricultural water use and industrial water use, and a one-way Granger causality between water resource use and economic growth. The cumulative pulse response of economic growth to gross water use is negative, and vise verse, that of agricultural added value to agricultural water use is positive, but agricultural water use to agricultural added value negative, both industrial added value to industrial water use and industrial water use to industrial added value negative. Except a higher contribution in agricultural added value to agricultural water use and industrial water use to industrial added value, economic growth has a less contribution to water use.  

This paper uses the three industries data and input & output model to analyze the overall industrial structure level and industrial correlation in Xinjiang, and finds out that Xinjiang is positioning at the para-industrialization stage led by the second industry, with a good developing trend, gaining some achievements in industrial structural adjustment. Issues are marked by irrational developing direction of the three industries that the first industry has a poor basis, easily subject to other industries, the second industry is still high-energy-consuming, high-pollution, low-technology without supports by high-technical industries, the third industry is lagging with low technicians. This paper presents suggestions on boosting the first industry, adjusting the second industrial structure, and developing the potential of the third industry, aiming at optimizing the third industrial structure and realizing long-term stable economic development in Xinjiang. 

 This paper uses their panel data of China's 52 resources-based cities in 2000—2015 to analyze their industrial structure deviation degree and establishes VAR model, which is used to study stability test, co-integration test, Graner causality, impulse response and variance decomposition panel data between industrial structure upgrade coefficient and employment. Results show that their industrial structure deviation degrees vary among developing, mature, declining and renewing resources-based cities, of which the best coordinated resources-based city is declining city, followed by mature, renewing and developing cities. The coordination of resources-based cities falls behind the average. A dynamic relation between structural upgrade and employment varies with different types of resources-based cities. VAR mode result shows that industrial structure upgrades of all resources-based cities make little contribution to employment, but employment improvement will influence industrial structure upgrade.

The economic globalization leads to a frequent and close trans national trading. Steel industry as China’s pillar industry provides vital basis for China’s economy. This paper uses Granger causality and 2003—2015 data to analyze the influence of China’s steel trade on economic growth. It concludes that steel export trade has a positive influence on economy, but its import has no obvious causality with economy. This paper presents suggestions on expanding steel export, which can deal with the excess of steel production capacity, and promote the economic growth as well.

The changes in land utilization have big influence over the ecosystem service function in mining area. This paper, based on land utilization data in Pingshuo mining area, studies the ecosystem service value in different land types and the total ecosystem value, indicates that the ecosystem service value had a decreasing trend during 1985 to 1990, from 312.7 million yuan to 303.48 million yuan, and a increasing trend during 1990 to 2005, up to 3110.9 million yuan. Two simulations with rehabilitation and without had been set to compare. Without rehabilitation, the total ecosystem value is decreasing, only 264.01 million yuan in 2005; while the total ecosystem value is increasing with rehabilitation, up to 498.36 million yuan in 2005, implying the rehabilitation plays a vital part in the sustainable development of ecosystem in mining area.

The results of the magnetic susceptibility of the Qidingshan loess varies in a range of 5.21×10^-8m³ kg^-1 to 42.42×10^-8m³ kg^-1, which is much lower than in other localities. The vertical changes of magnetic susceptibility and grain have a positive relation. The magnetic minerals are mainly focused on over 8ф in grain size. A comparison in Oxide isotope indicates that Qds20—Qds28 is consistent with the 3rd section of Guliya ice core and with abyssal 3a, 3b and 3c sub-section in fluctuation, and that Qds28—Qds31 is analogous with the 2nd section of Guliya ice core and with abyssal 2nd section. The study reveals during 60 to 22 ka BP the Malan loess sedimentation period is generally dry and cold with an interim warm and wet climate.

Mining area is one of strongest disturbed ecological systems by human being. People's mining has a great driving force to economy, but a big impact to the local environment. This paper, taking Pingshuo as a case study, applies marketing value method, cost method and mirror project method to study the ecological system service value changes triggered by land utilization changes during 1985 to 2005, with the results indicating that the ecological value fell from 312.71 million RMB to 303.48 million RMB during 1985 to 1990, slowly rose to 311.09 million RMB during 1990 to 2005. Rehabilitation led to a good ecological profit, which improved the ecological environment, increased the ecological service value, and mitigated the impact to surface.

A high solution analysis was carried out on loess particle at Qidingshan through screen method via SA-CP3 (a granularity analysis instrument made in Japan) and TL chronology, with the results that the loess granularity is dominantly coarse, coarse silt 4~6φ about 26.39~48.33%, a less clay (0.05~2.44%). At Malan, the loess granularity concentrates on two grades, 2~4φand 4~6φ, with coarse silt slightly more than fine sand. At Lishi, the loess granularity is dominantly 4~6φ. This paper, based on a comprehensive statistical analysis on sediment granularity parameters, indicates that there has been a big difference with inland winding loess since the middle Pleistocene. The loess sediment in Qidingshan is derived primary from a nearby source and secondarily from far source.
