This paper uses IPCC to measure the carbon emission in energy consumption and cement production in China’s 30 Provinces during 1997—2012, and applies Theil index and Kernel Density generalized matrix measurement to analyze the regional variance, trend evolution and factors of China’s carbon emission intensity. The results show an outstanding variance among eastern, central, western and northeastern with overall distribution variance coming from internal region. The carbon emission intensity has a falling trend in the above four regions with a concentrating distribution. The lagging item, urbanization level, foreign trading openness and energy consumption structure have a positive influence on carbon emission intensity, but the industrial structure and energy efficiency are negative. 

This paper, based on a case study on Xuzhou, analyzes Xuzhou's industrial waste gas emission and its trend, uses LMDI to attribute the factors of waste gas emission to energy intensity, industrial structure, economic growth and population growth. Economic growth is the major source of industrial waste gas; population growth promotes its emission; energy intensity and industrial structure can effectively confine its production. Further study shows that chemical, metallic and water, heating and electronic supply industries are the key sectors in producing waste gas, up to 90%. This paper presents suggestions on reducing industrial waste gas emission from optimizing industrial structure, improving energy structure and intensifying innovation.

The price system of rural collective-owned lands includes benchmark land-price for agricultural land and regional integrated price for land requisition, which were both confined to agricultural land; hence, this paper, based on a tentative practice on the benchmark price of rural collective-owned construction lands establishment, discusses some issues in gradation and calculation of collective-owned construction lands, aiming to provide a reference for optimizing measures for circulation of rural collective-owned construction lands.

This paper, based on a perplexing concept of basic farmlands, garden lands and wood lands due to agricultural adjustment, aims to clarify the definition of basic farmlands, by means of data review, theoretical study and logic analysis. The results indicate that the existing definition of basic farmlands can not meet the needs of practice, so it is necessary to redefine the basic farmlands, which shall not be occupied in a time or long term, well equipped with irrigation works, and can be altered or be excellent plantation, and its extension is a production base where can provide food and industrial materials, and its scope is enlarged to include garden lands besides other agricultural lands.

Gold production and consumption in China is increasing recently. Gold industry is stepping into group’s operation and sizable management. This paper, based on current status of Chinese gold producers, gold production, price and consumption, analyzes the gold industrial structure and presents a strategy for Chinese gold industry.
