摘　　要：以宁夏回族自治区隆德县为例,通过最小二乘法的回归分析,对1996—2011年宁南山区土地生态系统服务价值变动对经济发展的影响进行了研究。研究结果表明:(1)水域生态系统服务价值变动对隆德县经济发展的影响最大,应加强对水域生态系统的保护;(2)林地生态系统服务价值变动对隆德县经济发展的影响最小,应在稳定林地建设的基础上,着重发展后续生态产业;(3)农田生态系统服务价值变动对隆德县经济发展为正相关影响,其他地类为负相关影响,应设法增加农田的生态系统服务价值,同时适当控制林地、草地、水域、难利用地的面积;(4)难利用地生态系统服务价值变动对经济发展的影响偏小,说明隆德县的经济发展较为依赖自然资源,现代化程度低,应进一步优化产业结构,提高经济发展水平。In this paper, we made a scientific research on impact of the value change of land ecosystem serv- ices on economic development in mountainous area of Southern Ningxia Hui Autonomous Region from 1996 to 2011, by taking Longde County of Hui Autonomous Region as an example and based on the least square method. The results showed that： （1） The aquatic ecosystem should be strongly protected, as the value change of aquatic ecosystem services had the greatest influence on economic development in Longde County. （2） On the basis of steady forestry construction, the subsequent industry should be emphasized, as the value change of forest ecosystem services had the smallest influence on economic development in Longde County. （3） The value change of farmland ecosystem services had the positive correlation with the economic develop- ment in Longde County, in contrast, the others were negative correlation. In the future, the value of farm- land ecosystem services should be increased, while the area of forestland, grassland, aquatorium and the land difficult to use should be decreased properly. （4） The influence, which value change of ecosystem services of the land difficult to use had on economic development in Longde County, was relatively weak. This illustra-ted that the economic development of Longde County relied on natural modernization. So the industrial structure should be further optimized nomic development. resources and showed low degree of in order to improve the level of economic development.
