摘  要:
根据耕地集约利用的本质内涵,遵循系统性、典型性、科学性、可行性等原则,从耕地投入强度、耕地产出效率、耕地利用强度以及耕地利用可持续性状况等四个方面构建了山东省耕地利用集约度评价指标体系。采用均方差权值法对全省17地市耕地利用集约度进行评价,利用SPSS统计分析软件对17地市进行系统聚类。通过主成分分析方法对影响耕地利用集约度的诸多因素进行分析,将提取出的三个主成分作为自变量、耕地利用集约度作为因变量进行回归分析,定量剖析各因素对耕地利用集约度的作用方向及强度。研究结果表明:山东省耕地利用集约度存在较明显的空间差异,鲁南和鲁北地区耕地利用集约度较高,鲁中和半岛地区相对较低。经济发展因子与耕地利用集约度呈负相关,经济越发达,耕地利用集约度越低;土地资源禀赋因子和农业政策因子对耕地利用集约度的影响不明显,但仍存在一定的因果关系。

摘  要:
According to the essential connotation of cultivated land intensive utilization,and following the principles of systematicness,typicality,scientificity and feasibility,the evaluation index system of cultivated land utilization intensive degree in Shandong Province was constructed from four aspects of input intensity,output efficiency,utilizing intensity and utilizing sustainability of cultivated land. The mean-squared deviation weight method was used to determine the cultivated land intensity index and SPSS statistical analysis software was used to conduct cluster analysis. Through the principal component analysis,the factors affecting the intensive degree of cultivated land utilization were analyzed. With the three principal components extracted as independent variables and the cultivated land intensive degree as dependent variable,the regression analysis were used to quantitatively analyze the action direction and intensity of the factors to cultivated land utilization intensity degree. The results showed that there were obvious spatial differences in cultivated land utilization intensity degree in Shandong Province. Those in the south and north areas were higher,and those in the central region and peninsula region were relatively lower. There was a negative correlation between the economic development factor and cultivated land utilization intensity degree. The more the economy developed,the lower the intensive utilization degree of cultivated land was. The effects of land resource endowment factor and agri-cultural policy factor on cultivated land utilization intensity degree were not obvious,but there were still certain causal relationships.
