摘要
分析了陕西省2001—2010年土地资源利用的变化情况,采用层次分析法、变异系数法和比重法,选取经济、社会和生态3个层次18个指标对该省土地资源的利用情况进行了综合评价。通过确定各指标的权重,计算各指标的评价分值,评价了近10a来陕西省土地资源利用的总体水平。研究结果表明,2001—2010年,陕西省土地资源利用结构的转变符合经济和社会的持续健康发展要求,经济效益和社会效益呈现出稳步增长的趋势,年平均增长率分别为58%和21.5%,而土地资源利用的生态效益却直线下降。
The comprehensive evaluation and analysis of land resources utilization in Shaanxi Province from 2001to 2010were made by using analytic hierarchy process（AHP）,variation coefficient method and specific gravity method and selecting 18indicators from economy,society and ecology.After determining the weight of each indicator and calculating the indicator value,the general level of land resources utilization of Shaanxi Province in the past 10years was evaluated.Results show that the change of land resources utilization structure in Shaanxi Province was consistent with the sustainable development of economy and society from 2001 to 2010.Meanwhile,economic and social benefits of land resources utilization increased steadily and the average annual growth rates were 58% and 21.5%,respectively.However,the ecological benefit of land resources utilization showed a linearly decreasing trend.
