永定河上游流域土地利用变化及生态环境效应研究
Land use change and its ecological environmental effect in the upstream of Yongding River
摘要
Abstract
Based on the four spatial data sets of land use and land cover change of 1980,1990,2000 and 2010 in the upstream of the Yongding River,we quantitatively calculated the land use dynamic degree,the transfer matrix between the land use types and ecological environmental quality index,and analyzed the land use change and its ecological environment effect in the upstream of the Yongding River.The result shows that (1) During the past 30 years,the proportion of land use / cover in the study area was ranked as:farm land＞ grassland＞ forest land＞ urban and built up land＞ water ＞ unutilized land.The comprehensive dynamic degree of land use during 1980-1990 and 1990-2000 was 0.06％ and 0.19％,respectively,and the land-use change rates and transfer rates were not more than 10％ and the land use/cover change was small between the two period;while the comprehensive dynamic degree of land use was 6％and the land-use change rates and transfer rates were greater than 10％ during the period from 2000 to 2010,and the land use/cover changed greatly.(2) During 2000-2010,the regional eco-environment quality index increased from 0.4230 to 0.4290,and the regional eco-environment quality improved slightly;while the overall quality of regional eco-environment remained relatively stable,and the soil and water loss control measures and the expansion of construction land of the area had a profound impact on the regional eco-environment.The study provided the technical support for the land use structure optimization and the improvement of the ecological environment in the upstream of the Yongding River.关键词
