| Abstract: |
| The indices , waste gas, waste water, solid waste pollution subjects accounts and water resources accounts were added into the current ecological footprint model and the biological account, global average yields and productive land equalization factor were re-identifed to provide reference for mineral-grain compound area and key ecological functional areas comprehensive improvement in Xinzhou. Spatial differences of ecological footprint and ecological capacity among 14 counties (districts) in Xinzhou were estimated. The results were as follows: The ecological footprint per capita was mostly in the county with relatively rich energy resources, such as Jingle, Hequ,Baode, Yuanping. The ecological carrying capacity in Xinzhou was mainly derived from the cultivated land and the forest land, and the ecological capacity per capita concentrated on the resource-rich county with a relatively large population ,such as Ningwu, Jingle, Wuzhai, Kelan, Pianguan. During 2004—2009, the number of counties (districts) with ecological deficit increased and trended towards the serious deficit area and the area with pressure index greater than l generally. According to whether the occupancy rate of natural space on regional economic activities is higher than the average level of the whole city, Xinzhou City can be divided into two categories. The first type includes four counties which exceed the average level of the whole city, such as Hequ, Baode, Yuanping and Jingle. The technical efficiency is lower and the disturbance to the ecological environment is greater in these areas. The second type is the other eight counties, which are lower than the average level of the whole city. The technical efficiency is greater and the impact to the ecological environment is lower in these areas. Finally, we analyzed the causes of spatial differences from the perspective of energy utilization and urban development. The findings might provide the scientific evidence for the mine-food complex area and the ecological environment of the key ecological function areas. |
