摘要
采用主成分分析法,以县级行政单元为评价单位,对广西农用地集约利用进行定量综合评价,并对评价结果进行了聚类分析。结果表明:农用地处于高度集约利用状态的区(县)主要分布在合浦县、港北区、宾阳县、港南区、玉州区、柳江县、覃塘区、兴宾区等地区;农用地处于中度集约利用的区(县)主要分布在灵山县、钦北区、北流市、浦北县、钟山县、钦南区、桂平市、平南县、博白县等地区;一般集约和不集约主要分布在桂西北地区、梧州市、八步区等区(县)。研究结果基本符合区域农用地利用实际,对广西农用地高效集约利用和广西农用地资源利用区划具有一定的指导意义。
In order to understand the situation and spatial layout of agricultural land intensive use in Guangxi, the authors built a set of evaluation index system of agricultural land intensive use, using a principal component analysis method to make a quantitative and comprehensive evaluation on agricul tural land intensive use from county level in the province, and conducted cluster analysis with the e valuation results. The results show that in 2009 the agricultural land use in Guangxi could he classi fied into four grades as highly intensive use level, moderately intensive use level, general intensive use level, and nonintensive use level. The intensive use of agricultural land is mainly located in Hepu, Gangbei, Binyang, Gangnan, Yuzhou,Liujiang, Qintang, Xingbin and so on. Moderately intensive use of agricultural land is mainly distributed in Lingshan , Qinbei, Beiliu, Pubei, Zhongshan, Qinnan Gulping, Pingnan, Bobai,and so on; General intensive and nonintensive land use mainly distributed in the region of northwest Guangxi as Wuzhou, Babu district. The research results were in accordance with the actual conditions in Guangxi,which shows a certain significance to the intensive use and re sources use zone of agricultural land.
