- Abstract:
- The land cover map and database of Burang county are worked out by combining remote sensing and geographic information system. This article computes economic niche and landscape structure niche of agriculture, forestry and animal husbandry based on the theory of ecological niche concept as well as eight landscape indexes by aid of Fragstats module. It is summarized that rock is the background landscape which influences the ecological system health of Burang county, while natural grasslands and shrubs landscape are the main landscapes to maintain biologic diversity and ecology system health. The application of ecological niche theory to land cover embodies the ecological and economic niche of different landscape in Burang county by mutual functions of nature and society. Rock landscape is in the most stable state for it accounts for about 40% area of whole county. And tilth landscape have higher economic niche on the reasonable human interference though it has the lowest structure niche.
