摘　　要：商洛水源地是集中连片特殊贫困山区。运用生态足迹法对商洛水源地2009—2013年的生态足迹、生态承载力和生态盈亏进行了计算和分析,并对商洛水源地可持续发展状态进行了定量研究。结果表明:2009—2013年人均生态盈亏分别为0.146 737hm^2、0.067 036hm^2、0.079 039hm^2、0.005 687hm^2和-0.052 928hm^2,可持续发展能力呈下降趋势;2013年存在生态赤字,表明生态需求大于供给,开始进入不可持续发展阶段;经济发展依然落后,林地生态效益明显;有效地利用林地资源发展生态经济对提高区域可持续发展能力意义重大。The water resource area in Shangluo is the special area focusing on contiguous poor areas. With the ecological footprint analysis, this paper calculates and analyzes the ecological foot-print, ecological carrying capacity and ecological profit and loss to study quantitatively the sus-tainable development state of Shangluo water source 2009-2013. The results show that the eco-logical deficits per capita are 0. 146 737 hm^2 , 0. 067 036 hm^2 , 0. 005 687 hm^2 0. 079 039 hm^2 and -0. 052 928 hm^2 respectively from 2009 to 2013,with the ability of sustainable development displaying a declining trend. The ecological deficit existed in 2013,it was indicated that the ecological demand was greater than that of the supply, beginning to enter the stage of unsustainable development. The economic development still lags behind, and the ecological benefit of forest land is obvious. Developing ecological economy effectively by utilizing forest land resources is of great significance in improving the ability of regional sustainable development.
