摘要

[目的] 以山东省西部经济隆起带各县(市、区)为研究对象

对山东省西部经济隆起带耕地集约利用与空间分异进行评价和研究

为科学规划该区耕地资源

提高耕地集约利用水平

增加耕地产出及统筹区域农业发展提供参考。[方法] 基于县域尺度采用熵权TOPSIS法和GIS计算山东省西部经济隆起带各县(市、区)的耕地集约利用水平和空间格局。[结果] 山东省西部经济隆起带耕地集约利用水平分布表现为以东平县为界南部耕地集约利用水平低

北部高

北部中又以东北部耕地集约利用水平高

西南部低

中间一般

并存在"俱乐部趋同"的态势

即同一集约利用水平的耕地表现为集中成片分布态势;耕地集约利用水平各县(市、区)数量上呈现"金字塔"的趋势

即水平越高数量越少

水平越低数量越多;从指标层指标来看

化肥投入指数、机械投入指数、复种指数、机械化率、粮食安全指数、耕地安全指数、粮食单产和人均产粮是影响山东省西部经济隆起带耕地集约利用水平的主要指标。[结论] 山东省西部经济隆起带耕地集约利用水平分布具有明显的空间差异。

Abstract

[Objective] We take counties(city

area) of the western economic uprising belt in Shandong Province as evaluation units to study the intensity of cultivated land use and to analyze its spatial distribution in order to provide support for the cultivated land resources planning and the improvement of the intensity of cultivated land use to increase the output and the overall planning of regional agriculture development.[Methods] The intensity of cultivated land use and the spatial distribution of the western economic uprising belt in Shandong Province was analyzed with the entropy weight TOPSIS method and GIS spatial analysis.[Results] Taking Dongping County as a boundary

the intensity of cultivated land use is low in the south

and high in the north. With the north area

the intensity of cultivated land use is higher in northeast part

and lower in the southwest part. The middle area is in the average situation. There is a pattern of "club convergence" in the intensity of cultivated land use in counties(city

area)

that is to say that cultivated land with the same land use intensity are usually distributed together. The number of counties(city

area) with different intensities of cultivated land use showed a "Pyramid" trend

namely

fewer counties are with highest intensity and the more counties with lower intensity; In the index layer

the primary indicators of the intensity of cultivated land use are fertilizer input

mechanical input

multiple cropping index

the rate of mechanization

food security

index of cultivated land security

grain yield per unit area and per capita grain production.[Conclusion] The intensity of cultivated land use of the western economic uprising belt in Shandong Province showed an obvious spatial differentiation trend.
