The Regional economic development is the major drive to land utilization changes, of significance for high-efficiently land utilization. This paper, based on a case study on Yongqing county, Hebei province, analyzes the social-economic indexes and land utilization data with SPSS13.0 software and Excel tools, discusses the response of output, industrial structures, incomes and urbanization level to the land utilization changes. The results show that the main economic indexes have a good relativity to land utilization changes, meaning a land extensive utilization in Yongqing county, and a limited influence of construction lands on urbanization level which leads to a low urbanization level. This paper analyzes the social-economic factors to the land utilization changes, and presents approaches to the regional socialeconomic development and land utilization.

As economy goes on, the construction land demands become bigger and bigger. The prediction of construction demands during land utilization planning, however, still need to be improved. This paper, based on a case study on Dongfang city, Hainan province, establishes regress model and grey model of economic development to predict the construction land demands in 2010 and 2020, indicating that the regress model has a better application, but the grey model produces a bigger variation as years goes by, which can be applied for reference only by some correction.

Urban Land shows a different development pattern under the combined effects of the driving forces. Taking Qianxi county as a case, this paper uses extreme standardized method to deal with the county's eight townships driving forces indicator data and classifies the driving forces effects according to the total scores. Based on a system of urban land quality driving forces analysis layers, superposition analysis has been done on the basis of the land classification map and the factor scores level layers using Geographic Information System (GIS) technology. The result shows that the effect degrees and mining potential space of driving forces to land quality are different. Land production potential and basic establishment influence the land quality most distinctly, and they distribute from the lowest mining potential to higher mining potential on 4 standards. Urban location and urban convergency scale influence the land quality more distinctly. Urban location distributes from mining potential moderate to the highest mining potential, and urban convergency scale distributes from lower mining potential to higher mining potential on 3 standards. Regional economy develop level and integration service ability don't influence the land quality distinctly. Regional economy develop level is in mining potential moderate and higher mining potential, and integration service ability is in lower mining potential and mining potential moderate on 2 standards.The different of driving forces spatial effects reflects the strength or weakness of the urban on this aspect, and can guide the urban construction.

This paper, aiming at the dangerous aspects and potential accidents in coal-bed methane drilling projects, establishes a risk assessment system. The FAHP has been applied to assess the risks in coal-bed methane drilling project. The risk index system is defined through drilling projects, and assigned with weights by means of AHP. The risks are classified as key risks and common risks via the ABC classification method in economics. This method has been used to calculate the risk value in Sihe coal-bed methane drilling project, Jincheng, Shanxi province. The value is 4.1, meaning of big risk.

The environment in mining cities is frail, whose sustainable development catches much attention from public. This paper, based on an evaluation of ecological footprint models, analyzes the ecological footprint structure and loading structure in mining city Wu’an in 2005, compares among five other mining cities in regional resources utilization and sustainable development. The results indicate that the per capital ecological footprint is much bigger than per capital loading in mining cities, implying a deteriorating development. The ecological deficit is derived from big energy consumption in mining cities. This paper presents some suggestions for the sustainable development in mining cities.

The general urban planning is a major driver to the land price. This paper based on a case study of Tanghai county in Hebei applies spatial analysis, land price model and relativity method to study the spatial-temporal evolvement of urban land price driven by general planning, reveals a rule of planning on land price that a rational planning is helpful to increase urban land yield, achieving a highly efficient and intensive urban land utilization.
