[Spatial evaluation on ecological and aesthetic quality of Beijing agricultural landscape].
A total of ten single indices mainly reflecting the ecological and aesthetic quality of agricultural landscape, including ecosystem function, naturalness, 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.
