摘要
以宝鸡市土地利用经济效益评价为研究对象,选取了影响土地利用经济效益的10个指标,应用CD函数测算单独土地要素贡献率,从而更加准确的计算出各类土地经济产出值,再利用熵值法确定各项指标权重后进行协调度分析。结果表明:2000-2007年起宝鸡市土地利用经济效益呈现逐年增长的趋势,2008年土地利用经济效益协调度达到0.64,2009年达到(0.82)高度协调。通过对各因素影响程度的分析,为有效利用土地资源、提高土地利用经济效益提供参考。
The economic benefit of land use in Baoji City was evaluated based on selecting 10 factors which have effects on economic benefit evaluation,and the CD function was used for calculating the contribution rate of single land factor,therefore,the economic output value can be calculated more precisely.And then,the coordinate analysis was performed after the weight of each indicator was determined by the entropy method.Through the analysis,some suggestions were provided for more effectively using the land resources and improving the economic benefit of land use.According to the results,it can be seen that the trend of economic benefit of land use in Baoji City increased from 2000 to 2007.The degrees of economic coordination were up to 0.64 in 2008 and 0.82（high degree of coordination） in 2009,respectively.
