Analysis on Dynamic Characteristics of Landscape Patterns in Hailer and around Areas
This paper analyzed the spatial-temporal dynamic changes of land-scape patterns in Hailer and around areas. Firstly, landscape patterns types of research area were divided into water, sand, farmland, city and grassland based on remote sensing images of 1986, 1991,1996 and 2001 and field investigation. Then the grassland was classified into higher coverage grassland, high coverage grassland, medium coverage grassland and low coverage grassland by Normal-ized Difference Vegetation Index. Finally, the spatialtemporal dynamic changes of above-mentioned eight kinds of landscape patterns were analyzed using landscape ecology principle. The results indicated that human activities intensified significant from 1986 to 2001in research area. The area of grassland landscape decreased quickly, and the fragmentation extent intensified. The dominant landscape in research area changed from higher-high coverage grass-land to medium-low coverage grassland. The expansion of sand landscape is obvious in periphery of road, city and farmland. The grassland vegetation degenerated seriously. Fragmentation of city landscape lightened, and city land-scape patches tended to decrease and centralized. Economy development pat-tern of research area is in a stage that is transforming from extensive pattern to intensive urbanization pattern.
