Spatial-temporal Changes of Surface Cover Based on Landscape Pattern
Landscape pattern analysis is an important method to study comprehensive statistical analysis of the geographical condi-tions.Taking the desert and bare surface data of geographic condition census in an experimental area for example, the landscape indi-ces of the desert and bare surface, the nearest point index and area-weighted centuroid were calculated in different times using geo-graphic information system software, to analyse its spatial pattern evolution.The results showed that the patch area of the desert and bare surface has significantly reduced, the shape of patches tends to regularization, the fragmentation and aggregation degree has in-creased and spatial centroid migrate to the west gradually, even outside of the test area.The ecological environment has significantly improved the in the test region.
