An Evaluation Study on Comprehensive Benefits of Land Use of Jixi Coal City in Heilongjiang Province

提高煤炭城市土地利用综合效益是实现煤炭城市可持续发展的前提和基础,以黑龙江省煤炭城市鸡西市为例,在城市土地利用综合效益相关研究的基础上,以影响城市土地利用综合效益的经济效益、社会效益、生态效益为要素层,选择有代表性的25个指标,构建黑龙江省鸡西市作为煤炭城市的土地利用综合效益评价指标体系,运用最优组合赋权法确定指标权重,采用多目标综合评价法,对2003—2009年鸡西市土地利用综合效益进行了定量分析。结果表明:黑龙江省鸡西市7a间土地利用综合效益呈上升趋势,土地利用协调度呈下降趋势。表明鸡西市的土地利用综合效益还有很大的提升空间,可以通过提高土地利用协调度的方式来提高区域土地生态综合效益。
