长沙市土地资源可持续利用评价

从经济可行性、社会可接受性和生态合理性3个方面出发,构建了包括21个指标的长沙市土地资源可持续利用评价指标体系,根据《长沙市统计年鉴2010~2014》数据,运用多指标综合评价法、极值法、熵权法,对长沙市土地资源的可持续利用情况进行定量研究。结果表明:2009~2012年,长沙市的土地资源可持续利用情况得分不高,且伴有下降趋势,总体上处于可持续利用的起步阶段;2013年的可持续利用水平最高,并摆脱可持续利用的起步阶段,进入到可持续利用的发展阶段;2009~2013年,其可持续利用水平并不稳定。长沙市土地资源可持续利用水平总体上仍处于可持续利用起步阶段,可持续利用水平有待提高。
