株洲市土地利用综合效益评价

Comprehensive Benefit Evaluation of Land Use in Zhuzhou City

城市土地利用综合效益体现一个城市的综合发展水平。该研究从土地经济效益、土地社会效益、土地生态环境效益3个方面构建株洲市土地利用效益的指标体系，以株洲市2006~2013年的数据为基础，采用变异系数法确定指标权重，再利用加权函数法求得土地利用效益的综合分值，运用协调度模型分析土地利用系统协调性。结果表明：株洲市土地利用效益综合得分逐年递增，土地利用的协调度较低，分为基本协调和不协调两类。据此提出了提高株洲市土地利用效益的建议：继续稳步提升土地利用社会效益和经济效益。注重提高土地利用生态环境效益，实现土地利用三效益的综合统一。
