摘要:

生境质量的评估,对于维护区域生态系统,重塑区域生态安全格局有着重要作用。选取长株潭城市群作为研究对象,运用InVEST模型及ArcGis软件,分析2000年、2010年、2020年区域土地利用和生境质量的空间格局及时空演变特征,并进一步分析其演变机制与影响因素。结果表明:1)土地利用同生境质量水平的分布具有明显的相关性;2)长株潭城市群整体生境质量经历了一个努力维持到加速恶化的演变趋势;3)生境质量水平的动态演变与区域规划政策的发布落实有明显的相关性。

关键词: 长株潭城市群, 生境质量, InVEST模型

Abstract:

The assessment of habitat quality plays an important role in maintaining the regional ecosystem and reshaping the regional ecological security pattern.This paper selected the Chang-Zhu-Tan urban agglomeration as the research object,used the InVEST model and ArcGis software to analyze the spatial pattern and spatial evolution characteristics of regional land use and habitat quality in 2000,2010 and 2020,respectively,and further analyzed its evolution mechanism and influencing factors.The results showed that:1)The distribution of land use and habitat quality level had obvious correlation;2)The overall habitat quality of the Chang-Zhu-Tan urban agglomeration had experienced an evolutionary trend from maintaining in great efforts to accelerating deterioration;3)The dynamic evolution of habitat quality level was obviously related to the release and implementation of regional planning policies.

Key words: Changsha-Zhuzhou-Xiangtan urban agglomeration, habitat quality, InVEST model
