河北省耕地利用效益评价及其时空分异特征研究

为研究河北省耕地利用的经济效益、社会效益、生态效益、综合效益,以及对有关效益的综合评价,通过分析2000—2008年河北省各市县的耕地利用效益的时间动态变化特征和空间分异特征。研究结果表明:2000—2008年间,河北省耕地利用经济效益和生态效益呈现增长趋势,而社会效益则表现为逐年下降的趋势。河北省耕地利用各效益值的空间差异很大,耕地利用综合效益相对较高的地区主要集中在河北省北部唐山市、承德市和张家口市周围。研究成果对于保护耕地资源具有重要意义,为耕地利用发展提供理论依据及现实参考。

Cultivated Land Use Benefit in Hebei Province: Evaluation and Spatiotemporal Differentiation

The authors evaluated the cultivated land use benefit of Hebei Province from four aspects, including economic benefit, social benefit, ecological benefit and comprehensive benefit. The temporal and spatial variation characteristics of the cultivated land use efficiency in different counties of Hebei from 2000 to 2008 were analyzed. The results showed that the economic and ecological benefits of cultivated land use in Hebei Province showed an increasing trend from 2000 to 2008, while the social benefit showed a downward trend. The spatial difference of the cultivated land use efficiency was relatively large in the whole province, and the comprehensive benefit of cultivated land was relatively high in Chengde and Zhangjiakou. The research results have theoretical and practical reference values to the sustainable utilization of cultivated land resources in Hebei.
