基于土地利用的皖江流域生境质量时空变化特征分析
|
摘要
研究土地利用及其生境质量变化过程对区域生境保护、生态安全构建意义重大。以皖江流域作为研究区,在分析皖江流域土地利用变化的基础上运用InVEST模型对2000—2010的生境质量进行评估,总结皖江流域生境质量时空变化特征,结果表明:2000—2010,皖江流域的耕地面积减少最多,建设用地增加最多,土地利用类型转移主要为耕地转向建设用地;皖江流域的景观破碎度指数逐年上升,景观连通性差;皖江上游到皖江下游生境质量值逐渐递减,大部分皖江中下游平原区域生境质量值低于0.6,生境质量较差,皖江上游地区和山地丘陵地区生境质量值高于0.6,生境质量较好;2000—2010,皖江流域的GDP逐年增长,产业结构也逐步向二、三产业为主体发展,建设用地大面积扩张,整体生境质量下降明显。
Studying the process of land use and its habitat quality change is of great significance to the construction of regional habitat protection and ecological security bureau.Based on the analysis of land use change in the Yangtze River in Anhui region,the InVEST model is used to evaluate the habitat quality from 2000 to 2010 in this paper,and the spatial and temporal variation characteristics of habitat quality are summarized.The results show that:from 2000 to 2010,the area of cultivated land in the Yangtze River in Anhui region decreased the most,and the construction land increased the most.The land use type transfer was mainly the conversion of cultivated land to construction land.At the same time,the landscape fragmentation index increased from 2000 to 2010,and the landscape connectivity was poor.The quality of habitats in the upper reaches was higher than the lower reaches area.And the value of habitat quality in most of the middle and lower reaches was below 0.6,while the habitat quality values in the upper reaches were higher than 0.6.The GDP increased,and the industrial structure gradually developed into the secondary and tertiary industries from 2000 to 2010,in which the construction land expanded extensively and the overall habitat quality declined significantly.
