| 中文摘要: |
| 为了给忻州市矿粮复合区与重点生态功能区生态环境治理提供科学依据，在现有生态足迹模型中增加了包括废气、废水和固体废弃物科目的污染排放账户和水资源账户，重新确定了忻州各项生物账户全球平均产量与生产性土地均衡因子。采用修正后的生态足迹模型测算了忻州市14个县（区）生态足迹和生态承载力空间差异。主要结论为：人均生态足迹集中于能源资源相对丰富的县域，如静乐、河曲、保德、原平;忻州生态承载力主要来自于耕地与林地，人均生态承载力主要集中于相对资源富裕、人口较多的县域，如宁武、静乐、神池、五寨、岢岚、偏关；2004—2009年间生态赤字县域数量呈上升趋势，且整体上向严重赤字区、压力指数大于1的区域集中;依据区域经济活动对自然空间的占用率是否高于全市平均水平，可将忻州市分为两类区域，第一类包括河曲、保德、原平、静乐等4县超过全市平均水平，技术效率较低，对生态环境的扰动较大；另一类为其它8个县级单位，低于全市区平均水平，技术效率较高，对生态环境的影响较小。从能源利用与城镇发展角度分析了空间差异产生的原因。 |

| 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. |
