长江经济带生态系统宏观结构变化特征分析
Characteristic Analysis of Ecosystem Spatial Pattern and Structure in the Yangtze River Economic Belt.
摘要
Abstract
The Yangtze River Economic Belt is an important ecological security barrier of China. On the basis of ecosystem spatial pattern and structure datasets for 2000, 2010 and 2015, temporal and spatial change characteristics of ecosystem spatial pattern and structure were analyzed, using the method of transfer direction and extent of ecosystem, degree of dy-namic change in ecosystem type. The results show that the area proportion of forestland, farmland, grassland, settlement, water body and wetland, desert and other ecosystems in 2015 was 45. 96%, 30. 31%, 16. 58%, 3. 29%, 3. 06% and 0. 80%, respectively. The farmland area continued to decrease during the periods of 2000-2010 and 2010-2015, while the settlement area continued to increase. The changing rate of comprehensive ecosystem from 2010-2015 was higher than the previous period. Returning farmland to forest and grassland projects, expansion of construction land, and national strat-egy implementation were the major causes of the changing of regional land use.关键词
