| 摘 要： | 评价自然灾害前, 区域的生态足迹可了解当地自然生态系统的开发和利用状态, 结合主体功能分区的方法可为灾后重建提供更契合实际的政策建议. 基于合理灾后重建的理念, 从可持续发展的角度分析了2011年甘肃东乡"3.2"滑坡灾害发生前(2010年)县域生态足迹和生态承载力情况, 并根据海拔和坡度对区域进行功能分区. 结果表明: 草地人均生态足迹为0.94 hm2, 生态承载供给为0.022 hm2, 赤字0.92 hm2 , 草地土地类型存在严重的生态赤字, 直接导致整个县域人均生态赤字0.97 hm2. 这表明东乡县人民的消费需求超过了自然系统的再生能力, 人类的生产、 生活强度超过了生态系统的承载力, 区域生态系统处于人类的过度开发利用和压力之下. 由于进出口贸易不大, 因此, 东乡县主要是通过消耗自然资本存量来弥补生态承载力的不足. 考虑到东乡县的实际情况, 通过主体功能分区把该区域分为农业发展区、 生态恢复区以及二、 三产业发展区. 其中, 农业发展区面积为838.24 km2; 生态恢复区面积为701.98 km2, 包括退耕还林的面积264.84 km2; 二、 三产业发展区面积105.57 km2. 最后根据生态足迹和功能分区的计算结果, 结合实际情况提出了未来可持续发展的政策建议.

| Abstract: | Human over-exploitation and over-use of natural resources can result in disasters. The disastrous consequences due to over-use of resources can be assessed through ecological footprint. In addition, proper policy of post-disaster recommendation must be provided by using major function regionalization. Because of a landslide hazard took place in Dongxiang County in 2011, it is necessary to calculate and analyze the ecological footprint and ecological carrying capacity of the county in 2010 based on the concept and calculation method of ecological footprint indicator for reconstruction of the landslide hazard area. Moreover, according to the altitude and gradient indicators, the county is divided into regions of various major functions. The calculating results of ecological footprint indicator show that grassland per capita ecological footprint is 0.94 hm2, ecological carrying capacity (bio-capacity) is 0.022 hm2, with a deficit of 0.92 hm2, and the whole county per capita ecological deficit is 0.97 hm2. The results show that the consumer demand in the county has already exceeded the regional bio-capacity, and the regional natural ecosystem is under a great pressure of human activities. Owing to low level of import and export trade, Dongxiang people have to compensate the lack of ecological carrying capacity mainly through consumption of natural capital stock. Besides, the county is divided into agricultural development regions (838.24 km2), ecological recovery regions (701.98 km2) and second and third industrial regions (105.57 km2). Finally, policy is recommended for sustainable development according to the actual situations. |
