选择了重点反映农业景观生态与美学功能的生态系统功能、自然性、开阔与多样性、污染概率和整洁度等10个单一空间显性指数，基于田间调查和专家系统赋予其不同权重，构建了农业景观质量综合评价指标，并基于地理信息系统支持下的土地利用数据和利用遥感获得的植被指数，对北京市农业景观质量及其空间差异进行了评价.结果表明：北京市农业景观质量的区域差别较大，城区及小城镇边缘的农业景观质量最差，近郊外围及远郊区较好；北京市农业景观的优劣主要与地形和人为压力有关.基于空间信息技术和景观指数，在大尺度上构建的综合指标体系，对评价农业景观质量的空间差异具有重要意义.
A total of ten single indices mainly reflecting the ecological and aesthetic quality of agricultural landscape, including ecosystem function, naturaln
ess, openness and diversity, contamination probability, and orderliness were selected, their different weights were given based on field survey and expert system, and an integrated evaluation index system of agricultural landscape quality was constructed. In the meantime, the land use data provided by GIS and the remote sensing data of vegetation index were used to evaluate the Beijing agricultural landscape quality and its spatial variation. There was a great spatial variation in the agricultural landscape quality of Beijing, being worse at the edges of urban area and towns, but better in suburbs. The agricultural landscape quality was mainly related to topography and human activity. To construct a large-scale integrated index system based on remote sensing data and landscape indices would have significance in evaluating the spatial variation of agricultural landscape quality.
