摘要:
耕地集约利用水平影响着国家粮食安全及区域的可持续发展,以河南省18个地级市为评价单元,采用最优组合赋权法、协调度评价模型、聚类分析法、GIS空间分析方法定量分析了1989—2008年间河南省耕地集约利用水平的时空变化特征。结果表明:1989—2008年间河南省耕地集约利用水平呈波动上升的趋势,其耕地投入强度和利用效益对耕地集约利用水平影响较大;省域范围内耕地集约利用水平空间差异显著,呈现4级分布,河南北部、东部、南部地区耕地集约利用水平较高,中部次之,西部相对较低;区域间投入强度、利用程度和利用效益差异明显,且出现错位发展。1989—2008年间河南省耕地集约利用水平逐步提高,平原地区的耕地集约利用水平高于山地丘陵地区,且向山地丘陵地区不断扩展,评价结果与现实情况基本一致。
Abstract:
The level of intensive use of cultivated land is related to national food security and regional sustainable development. This paper took 18 cities as evaluation units to quantitatively analyze the spatio-temporal variance features of the arable land intensity from 1989 to 2008 in He’nan Province. Methods of optimal weights combination, coordination function, cluster analysis and GIS spatial analysis were employed. The results indicated that the intensive use level of cultivated land from 1989 to 2008 in He’nan Province had been fluctuating up. The level of cultivated land intensive use was prone to be influenced more by investment degree and utilizing efficiency of cultivated land. The intensive use level of cultivated land took an obvious territorial differences and appeared four-grade distribution in provincial domain-wide; it was the highest in north, east and south, secondary in the center and the lowest in the west. The investment degree, utilizing intensity and efficiency of cultivated land appeared evident differences and inconsistency. The authors concluded that the intensive use level of cultivated land from 1989 to 2008 raised step by step in He’nan Province, it was higher in the plain area than that in the hilly area, and unceasingly expanded to the hilly area, the results of evaluation were consistent with the realities.
