| 为了验证绿心地区土地利用变化对生态系统服务价
值(ESV)的影响，运用2008、2013、2018年的土地利用数
据，综合当量因子法、格网分析法、空间自相关分析、相关性
分析及变差贡献率分析等，研究绿心地区ESV的时空动态变
化。结果显示，绿心地区的耕地面积持续减少，建设用地和林
地面积明显增加；ESV在早期呈下降趋势，但2013年后转为
上升趋势；生态水文调节、水资源供给和气候调节功能增长明
显；土地利用变化与ESV的相关性排序为：林地＞耕地＞水
体＞草地＞未利用地＞建设用地；变差贡献率中，林地、水体
和耕地的贡献率较大，其他土地利用类型贡献率较小。研究结
果表明，自2013年以来绿心地区的开发建设和保护工作有序
进行，ESV呈明显增长趋势，说明合理开发和严格控制生态
底线的保护模式可以提高其ESV，采用保护为主、开发为辅
的保护策略是可行的。 |

| Abstract: |
| In order to understand the impact and status of land use
change on the ecosystem service value (ESV) in the green heart
area of the CZT, this study used land use data of 2008, 2013 and
2018 processed by ArcGIS to analyze the spatiotemporal dynamic
change of ESV of the green heart area with the equivalent factor
method, the grid analysis method and the spatial auto correlation
analysis method. The results found that the cultivated land area
continued to decrease, and the construction land and forest land
increased significantly; the ESV decreased in the early stage, but
increased after 2013; the functions of hydro-logical regulation,
water supply and climate regulation increased significantly. The
development, construction and protection of the green heart area
have been carried out orderly since 2013, and the ESV has shown
an obvious growth trend. It implicated that the protection mode of
reasonable development and strict control of ecological bottom line
may improve the ecosystem service function, and it is feasible to
adopt the protection strategy with protection as the main factor and
development as the supplement |
