Abstract
With theory support of the first law of geography spatial variance of land use landscape in Haidian District of Beijing is analyzed with geostatistic tool and grid sampling method. The spatial organization and mechanism of urbanization can be well understood by reveal of spatial characteristics of artificial impact and ecological effect. The results show that: (1) characteristic of spatial variance can be well described with GIS-based geostatistic method. The spatial correlation characteristic has been shown clearly in indices, especially for human impact index, which has stronger spatial organization. (2) spatial correlation of two indices are strongly dependent at this study scale. And spatial variance is mainly produced by structure factors, namely regional factors such as hydrology, soil and light etc.
