| 摘 要： | 从土地具有多宜性和耕地具有多功能性的角度出发,构建了耕地自然适宜性评价指标体系、经济适宜性评价指标体系和生态适宜性评价指标体系,基于北京市自然、社会、经济资料及图形资料,运用GIS地理空间分析功能,通过对评价要素的空间叠加、计算,评价了北京市耕地不同利用目标下的适宜性级别和面积,结合不同的发展阶段耕地承担的不同功能,对耕地的多目标利用类型做了分析。结果表明:耕地自然适宜性高、中、低的面积分别为1207.65km2、920.16km2、193.99km2;耕地经济适宜性高、中、低的面积分别为:1077.86km2、1002.55km2、241.39km2;耕地生态适宜性高、中、低的面积分别为1170.46km2、1044.25km2、107.09km2。为了体现耕地多目标适宜的弹性空间,设计了经济效益型、社会效益型、生态效益型3种方案,并对不同的发展目标下的投入水平做了探讨,评价结果可为城市新增建设用地的时空配置提供参考。

| Abstract: | Methods for suitability evaluation of cultivated land for multi-purposes use and spatio-temporal distribution were investigated in this paper based on current natural, social and economic situations as well as associated maps of Beijing. With the spatial analysis methods and software packages of GIS, natural suitability evaluation, economic suitability evaluation and ecological suitability evaluation of cultivated land in Beijing were performed in succession. Suitability ranks and areas were estimated by me... |
