| 摘 要： | 采用因子分析法,对河南省18个地区2000年和2005年的耕地集约利用水平进行定量评价和等级划分.研究结果表明,(1)投入水平、产出水平、农业保障水平和集约利用水平是影响河南省耕地集约利用水平差异的主要因子,但4者之间的协调性较差.(2)单纯以投入水平或产出水平来衡量耕地集约利用水平差距具有一定的局限性.(3)耕地集约利用水平地域分布不均衡,豫北地区的耕地集约利用水平相对较高.(4)耕地集约利用综合水平与其4个主要因子,即投入因子、产出因子、农业保障因子和集约利用因子等,呈现出不一致的分异现象.(5)全省的耕地集约利用水平呈现出下降的趋势,且综合指数和4个主要因子的极差均出现了扩大的现象.

| Abstract: | By taking He'nan Province for an example, factor analysis method is used for the quantitative eva-luation and rank division about intensive utilization levels of arable land in 2000 and 2005. Results show that (1) input level, output level, agricultural protection level, and intensive utilization level are the main factors that influent intensive utilization levels of arable land in He'nan Province, but the coordination of the four is poor. (2) Only measuring the gap between the levels of intensive utilization of arable land by input level or output level has certain limitations. (3) The intensive utilization levels of arable land in the northern part of He'nan Province are higher than other parts. (4) There is a difference in the inconsistency between the comprehensive levels of intensive utilization of arable land and the main factors, that is, input level, output level, agricultural protection level, and intensive utilization level. (5) The intensive utilization levels of arable land show a downward trend in the whole province and the range of composite index and the four factors increases. |
