To assume China ’coal production center migration trend is based not only on coal resource potential, but also on utilization cost, social cost, environmental benefit, in accordance with synthetic evaluation on coal resources, hence, synthetic evaluation system is employed to help assume the coal production center migration trend. This paper builds up a regression model based on China’s synthetic evaluation results on coal resources, which indicates the trend will go westward that Gansu and Ningxia will become centers in a short term, Xinjiang in a long term.
The land sustainable utilization becomes a hot point. It is a land research frontier to establish index system in evaluate the land sustainable utilization and to apply it in practice. This paper uses entropy method to study Huludao,s land sustainable utilization, and shows that 2003-2009 was the beginning and had a rising trend in resources, environment, economy and society, implying a big potential. This paper presents suggestions for the future land sustainable utilization in Huludao in forestry construction and eco-environment, developing coastal cycling economy, boosting land development, rehabilitation and consolidation, and controlling popular growth.
Xinjiang＇s traditional coal resources are developed in a primitive way with a low added value and wasted resource, which is harmful to environment and requires an extended coal industrial chain maximizing the comprehensive benefits of coal industry. This paper, according to industrial chain theory, analyzes the input/output data, establishes a coal industrial chain which is based on coal-power, coal-chemicals and highly-energy-consuming industry, and extends the chain to market. At the same time, a transverse chain is also set up based on finance-coal-transportation and stock.
Hangzhou is a very famous city with reputed resorts and historical culture, and possesses abundant geological relic resources, especial the lakes, karst, tides and the Neolithic ancient human being’s relics. This paper, based on the genesis, materials and the dynamic factors contributing to the geological relics, classifies the geological relics into eight types, and expands the typical ones. According to the spatial distribution and combination, this paper assorts Hangzhou into four regions such as Xihu lake, Liangzhu, Lunian and Heshang, and presents some suggestions protecting and developing the geological relic resources in Hangzhou city.
