山东省耕地利用效益的时空差异

文章尝试性地提出耕地利用效益评价指标体系,采用主成分分析、聚类分析和相关分析,并以农业大省山东为例进行实证研究,以揭示区域耕地利用效益的时空差异和特征,为制定提高区域耕地利用效益的对策、为国家制定耕地利用、保护和耕地整理、补偿政策提供参考。研究结果表明,耕地资源利用效益存在着巨大的时空差异;森林覆盖率、人均粮食产量、人力资本水平等8项指标是决定耕地利用综合效益的主要因素。主要结论或政策启示是:政府对耕地的保护政策、补偿政策,不仅要考虑耕地数量,更要考虑耕地利用效益状况,实行高效益高保护、高补偿。

STUDY ON THE DIFFERENCE IN TIME AND SPACE FROM THE UTILIZATION BENEFIT OF CULTIVATED LAND IN SHANDONG PROVINCE

This paper tries to put forward the indicators for analyzing the utilization benefit of the cultivated land resources empirically for the case of Shandong province,by the principal component analysis,cluster analysis and correlation analysis,to bring the differences from the utilization benefit of the cultivated land resources to light,in order to present empirical references for the government to make the policies of the utilization,protection,compensation and trim of the cultivated land.Outcome means the huge differences in time and space from the utilization benefit of the cultivated land resources.Analysis means that the 8 indicators,such as forest coverage rate,food per capita and so on,are the main factors to control the comprehensive benefit for the utilization of the cultivated land resources.This paper enlightens us that the government not only considers the amount of cultivated land,but also the utilization benefit of the cultivated land resources when makes the policies of the utilization,protection and compensation of the cultivated land: high benefit for high compensation and high protection of the cultivated land.
