    摘要:

    以乡镇为基本研究单元,选取生态压力、生态敏感性、生态恢复力3个因子对宁夏限制开发区的生态脆弱性进行了评价,并探讨了其区域发展模式。生态脆弱性评价结果显示,宁夏限制开发生态区生态脆弱性可分为极度脆弱、高度脆弱、中度脆弱、低度脆弱共4个等级,其中,极度脆弱区面积达到研究区总面积的51.76%,高度脆弱区占21.15%,中度脆弱区占15.56%,低度脆弱区占11.52%。针对研究区生态脆弱性状态提出了5种区域发展模式(即以生态补偿为主体的发展模式;以生态移民为主体的发展模式,基础设施建设推动型发展模式,以生态草畜业为主体的发展模式和现代农业发展模式。

    Abstract:

    With the township as the basic units, the ecological pressure, ecological sensitivity, ecological resilience were selected to evaluate the ecological vulnerability of the restrict development area in Ningxia Hui Autonomous Region, and the development model that suitable for the region was explored. The ecological vulnerability assessment results showed that the ecological vulnerability in the study area is divided into extremely fragile, highly fragile, moderate fragile, fragile, of which, extremely fragile areas covers 51.76% of the total area, highly fragile areas covers 21.15%, moderately fragile areas covers 15.56%, low fragile areas covers 11.52%. For practical ecological fragile in the study area, five regional development model were presented as follows: ecological compensation as the main way, immigration as the main way, promoted by infrastructure construction, ecological livestock industry as the main way, and modern agriculture.
