摘要
该文从县域经济重要性的角度分析了县级尺度土地资源可持续利用、管理和规划的重要意义。以土地资源可持续利用的基本原理为基础 ,采用“多指标集合度量法”的概念和模型 ,构建了县级尺度土地资源可持续利用指标体系框架 ,具体包括目标层、准则层、因子层和指标层等不同层次 ,目标层反映土地资源可持续利用总体目标 ,准则层反映土地可持续利用的 5个准则 ,即生产性、安全性、保护性、经济可行性和社会可接受性。以江苏锡山市为例 ,采用综合指数方法与单指标多角度评价方法相结合的方法 ,侧重于对每项指标的多角度分析和土地资源可持续利用变化过程分析 ,评价了锡山市土地资源可持续利用状况 ,论述了目前与将来影响锡山市土地资源可持续利用中存在的问题 ,提出了实现可持续性土地利用与管理目标的解决途径。
It is necessary to evaluate sustainable land use at the county scale in China. By taking Xishan city of Jiangsu province in eastern China as an example, an index system for sustainable land use at county scale is put forward based on the character of sustainable land use indicators and the trait of land resources in county. The system is made up of three levels as objective, criterion and indicators. The objective is sustainable land use. The criterion level is made up of five criterions of productivity, security, protection, availability and acceptance. The indicators are the data used to evaluate sustainable land use. In addition, the methods to acquire these indicators in order to make the framework more applicable are introduced. Based on the index system for sustainable land use at county scale and the land use conditions in Xishan city, comprehensive index assessment is combined with single indicators from multi-angle methods to evaluate the sustainable land use status of Xishan. The sustainable degree of Xishan can be regarded as middle sustainable land use. Furthermore, the problems that may influence the sustainable land use at present and in the future are pointed out and some useful suggestions concerning sustainable land use and management are provided.
