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

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

  • 摘要: 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

     

    Abstract: 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
