Analysis on spatial structural characteristics of land use of Beijing City

Analysis on spatial structure characteristics of land use is very significant for reasonable land use in the future of Beijing, where was the study area. This paper, from landscape, economic and ecological points of view, expounded spatial structure characteristics of land use of Beijing. And a series of indexes such as land use diversity, land use extent, economic density and ecological value were applied to analyze the spatial structure characteristics of land use for the year 2006. These indexes were all gridded with 1km×1km cells to detect spatial heterogeneity. The results showed that land use category of Beijing was complete in 2006. The land use, cover diversity index and the land use extent index turned out to be gradually increasing from the mountainous regions in northwest Beijing to the plain regions in southeastern part. The average land economic density of Beijing for 2006 was 47.97×106 RMB/km2. Meanwhile, the economic density of forestland was minimum, on the contrary, that of urban and town characterized by concentration and aggregation was maximum. The total ecosystem services value for the study area was 13 488.13×106 RMB with the average of 0.82×106 RMB/km2, which was a little bit higher than the national average level. Authors suggested efficiency and effectiveness of land use need to be further improved to make land use of Beijing more sustainable.
