成都市土地资源可持续利用评价

Evaluation Research on the Sustainable Utilization of Land Resources of Chengdu

土地资源可持续利用评价是衡量土地资源是否达到合理利用的评判标准,是评价和监测土地可持续利用的状态和程度。从环境、资源、经济及社会四个准则层出发,选取21个因素作为参评因子,建立评价指标体系;运用基于时点评价法、线性比例法与熵权法进行综合测算,对成都市土地资源可持续利用进行针对性的实践研究。结果表明,成都市土地可持续利用处于一般可持续利用状态,整体态势良好。但成都市土地利用的环境保护性还有待进一步加强,注重协调耕地与社会经济发展的关系,进一步提高耕地的土地利用效益。
