西藏曲水-桑日地区1988-2009年土地利用景观格局演变研究
Study on Landscape Evolution in Qushui-Sangri Area of Tibet from 1988 to 2009
摘要
Abstract
Land use patterns reflect the environmental characteristics and socio-economic development model, and provide a reference for resource development and environmental protection. Land use and its evolution information in study area were extracted by calculating landscape pattern metrics and transition matrix based on remote sensing data in 1988, 2000 and 2009. The results showed that each type of land use was shifted, the shifted area occupied for 6% of total area. The rate of land for bush beaches, sand and grass was greatly changed. The area changes of arable land and sand land firstly increased and then decreased; construction land and mining land increased continuously, alpine lakes generally reduced. The average area of land use patch increased, and patch density decreased, which contagion change firstly increased and then decreased, but the change trend of edge density, total boundary length and intersperse and juxtaposition index firstly decreased and then increased. Fragmentation increased, edge density of forest, building land and mining land increased; the average patch area increased first and then decreased; intersperse and juxtaposition index of beach and lake decreased, but intersperse and juxtaposition index of mining land increased. The result also showed that there was a close relationship between the landscape pattern and climate change, and human economic activities. This study result is important for government departments to protect land resources.关键词
