耕地集约利用动态评价及障碍因素诊断研究——以河北省为例

本文从投入强度、利用程度、产出效果和持续状况四个层面构建耕地集约利用评价指标体系,利用熵值法确定指标权重,分析了1994-2008年河北省耕地集约利用水平及障碍因子。研究结果表明:(1)1994-2008年河北省耕地集约利用水平呈波动上升趋势,大致经历以下三个阶段,1994-1999年为波动阶段;2000-2003年为平稳阶段;2004-2008年为上升阶段;(2)1994-2008年河北省耕地集约利用的障碍因子主要为人均耕地、劳力投入、复种指数、地均产量、劳均产值和非农指数。从长远来看,人均耕地和劳力投入的障碍度呈上升趋势,非农指数的障碍度呈下降趋势。最后,根据评价结果提出了提高耕地资源集约利用水平的对策建议

Dynamic Assessment of Intensive Utilization of Cultivated Land and Obstacle Factors Diagnose in Hebei Province

In this paper,an index system was established from four aspects: investment degree,utilization degree,use efficiency and sustainable utilization.The weight of each index was calculated by the entropy method.On the base of those,the level of the cultivated land intensive use during 1994-2008 was calculated,and obstacle factors were also diagnosed in Hebei Province in this paper.The results indicated that:(1) from 1994 to 2008 the intensive use level of cultivated land in Hebei Province had been fluctuating up,experiencing the stages of fluctuation in 1994-1999,smoothness in 2000-2003 and rapid development in 2004-2008;(2) the main obstacle factors were per capita cultivated land,labor input,multiple cropping index,output per cultivated land,the output value per person and non-agriculture index.In the long run,the obstacle degree of per capita cultivated land and labor input continue to show an upward tendency,but the obstacle degree of non-agriculture index shows a downward tendency.Finally,according to the evaluation results,we put forward some recommendations about promotion of cultivated land intensive use.
