【摘要】 景观分析与评价是景观生态学的研究核心问题之一，本文用地理信息系统（ARCINFO）、分维分析和统计分析以及耕地利用景观质量评价相结合，以1：1万土地利用现状图为基础，研究了城市化特征明显的北京良乡卫星城的耕地利用景观空间格局特征和动态变化。结果显示：城郊区域的耕地利用景观明显不同于农业区域的耕地利用景观，主要表现在斑块面积小，分维指数较高，耕地利用景观质量指数低等；同时，随着城镇扩展，耕地景观趋于破碎，其耕地利用景观质量呈现明显下降。更多还原

【Abstract】 The Landscape analysis and evaluation is an important component of the landscape e-cological study. Combined with fractal dimension analysis, statistical methods and evaluation ofthe farmland use landscape’s quality based on the 1:10000 land use map), the spatial pattern,and features of farmland use landscape in Liangxiang of Beijing were studied. The resultsshowed the patches of farmland in the surburb were of the Smaller area, higher index of fractaldimension and lower quality index of farmland use landscape, which was different from that inthe agricultural area. At the same time, the farmland use landscape became fragmental and thequality of farmland use landscape became worse as the town developed.更多还原
