山东省南四湖流域耕地集约利用空间分异特征

Spatial Differentiation of Cultivated Land Intensive Use in Nansihu Basin of Shandong Province

在分析耕地集约利用内涵的基础上,以山东省南四湖流域28个县(市、区)为评价单元,采用熵值法、综合指数法和GIS相结合的方法对2011年该流域耕地集约利用空间差异进行了分析。结果表明,山东省南四湖流域耕地集约利用水平受区域自然、经济和社会条件的差异影响,具有明显的区域空间分异特征,表现为湖东低山丘陵区耕地集约利用水平明显低于湖西黄泛平原区;耕地集约利用水平不同的县(市、区),其提高耕地集约利用水平的措施也不相同。

Taking 28 counties（city or area） as evaluation units, the spatial differentiation of cultivated land in- tensive use in Nansihu Basin of Shandong Province was analyzed by adopting entropy and comprehensive in- dex method combine with GIS in 2011. The results showed that the intensive use level of the cultivated land in Nansihu Basin revealed obvious regional differentiation characteristics which influenced by the natural, social and economic conditions of the regions. The intensive use level of the low hilly land in the east lake is significantly lower than that of the Yellow River flood plains in the west lake. Moreover, the measures to improve the intensive use level of cultivated land are different for different counties（city or area）.
