Analysis of Dynamic Change in Wetland Landscape in Agro-pastoral Ecotone——A Case Study of Duolun County, Inner Monglia
摘要
Abstract
Based on the remote sensing data of wetland in 1987, 2000 and 2010, the spatio-temperal change of wetland in Duolun County and its driving force were analyzed. The result showed that the wetland area increased from 1987 to 2010, and the total reduced area was 13 504. 63 hm2. The transfer rates of swamp wet-land and river-reservoir wetland form 1987 to 2000 were -1.74% and -0.12%, respectively. The transfer rates of swamp wetland and river-reservoir wetland from 2000 to 2010 were-4. 81% and 0.18% , respectively. More than 90% of the wetland area was conversed to non-wetland including forestland, grassland and farmland. The transfer rate from 2000 to 2010 was 1. 3 times of the rate from 1987 to 2000. Swamp wetland demonstrated the net increase from 1987 to 2000, and river-reservoir wetland presented the net increase from 2000 to 2010 in terms of the internal transfer. The result of principal component analysis of driving force showed that the main natural factors which made wetland decrease were dry and hot climate. Population growth and a series of chain reaction from it led to the decrease of wetland area. Meanwhile, proper policy guide can deal with the conflicts among population, resources and environment, and protect wetland.关键词
