生态脆弱城市三峡库区重庆市万州区土地资源可持续利用评价

Evaluation on Sustainable Utilization of Land Resources in Wanzhou District of Chongqing City,Ecologically Vulnerable City of the Three Gorges Reservoir Area

土地是人类生存和发展的重要载体,提升区域内土地良性循环对脆弱生态区可持续发展具有重要的现实意义。以生态脆弱城市三峡库区重庆市万州区为研究对象,采用综合指数与单指标多角度分析相结合的方法,对研究区域的生态脆弱区土地资源可持续利用进行评价,研究结果表明,万州区的土地资源可持续利用综合指数为0.6032,处于基本可持续的阶段;而土地资源稳定性和生态环境保护性均处于弱可持续阶段。因此,万州区土地资源处于弱可持续阶段。提出增加绿化防治水土流失,提高有效灌溉率,整合土地以提高土地利用率的对策建议。

Land is an important carrier for human survival and development.Improving the virtuous cycle of land within a region has important practical significance for the sustainable development of fragile ecological regions.Taking Wanzhou District of Chongqing City,the ecologically fragile city of the Three Gorges Reservoir Area,as the research object,the method of combining comprehensive index and single index multi-angle analysis was used to evaluate the sustainable utilization of land resources of the study area.The results showed that the comprehensive index of sustainable utilization of land resources in Wanzhou District was 0.6032,which was in a basically sustainable stage.The stability of land resources and the protection of ecological environment were both in a weak sustainable stage.Therefore,the land resources in Wanzhou District were in a weak sustainable stage.Suggestions for increasing greening to prevent soil erosion,improving effective irrigation efficiency,and integrating land to improve land use efficiency were proposed.
