摘要
在TOPSIS方法下,充分考虑土地投入和土地产出,结合变异系数法确定权重,构造农用地、建设用地和土地利用综合效益评价模型,对我国31个省(市、自治区)2008—2010年的农用地综合效益、建设用地综合效益、土地利用综合效益进行定量评价。研究表明:①我国土地利用效益偏低,2010年全国平均土地利用综合效益值仅约0.28;②我国土地利用"成本投入—效益产出"比过高;③我国地域差异显著,农用地综合效益东北>东部>中部>西部,建设用地综合效益东部>中部>西部>东北。在此基础上,提出了土地高效益利用的对策与建议。
From the two aspects of the construction land and agricultural land, the article created a comprehensive land use efficiency ew luation model of China's 31 provinces from 2008 to 2010.It made quantitative evaluations on their agricultural land efficiency, construction land efficiency and integrated land use efficiency with introduction of the coefficient of iation method to determine the weight, combined with the weighted TOPSIS method .The research showt Land use efficiency in China is low, and the national average integrated land use efficiency value is only about 0.28 in 2010; (2) The "input- output" ratio of land use in China is too high; @There are significantly different issues on and use efficiency of different manners of land use in different regions. In this regard, the article proposed countermearures and suggestions on the high efficiency of land use.
