| Abstract: | By the way of RS and GIS, and on the base of great many data, the status of landscape pattern and processed data of Ⅳ satellite RS of Yanchi County was analyzed. The results indicate that Yanchi's landscape pattern changes significantly during the research phase,fragmentation and diversity index of entire landscape keeps on the rise, the dominance index reduced, and the evenness index increased. The pattern shows a varied development tendency of agriculture, forestry and animal husbandry. At the same time, the condition of ecological environmentof Yanchi County has been improved step by step. |
