摘要: 霍山县位于大别山国家重点生态功能区范围内,研究其生态系统服务价值变化对于协调区域经济发展和生态环境保护之间的关系,制定区域经济发展规划以及优化配置土地资源具有重要的参考价值。基于RS和GIS技术,获取霍山县1990—2020年7期的土地利用数据,参照谢高地等2008年的中国陆地生态系统服务价值系数,根据Thornthwaite Memorial气候生产力模型,得出霍山县生态系统服务价值修正系数。在此基础上,从土地利用变化的速度、方向以及利用程度3个方面,分析土地利用转型对霍山县生态系统服务价值变化的影响,并对其结果进行空间自相关及冷热点分析。结果表明:1)1990—2020年霍山县土地利用变化整体较慢,其中建设用地、耕地变化幅度较大,幅度分别达到402.58%、-5.13%;2)从土地利用转移方向上看,霍山县土地转出贡献率最高的为林地,土地转入贡献率最高的为建设用地;3)土地利用综合变化指数大于0,县域土地利用处于发展期;4)30年来霍山县生态系统服务价值出现了一定程度的下降,其中林地生态系统服务价值减少量最大;5)霍山县的生态系统服务价值空间格局呈现明显的空间自相关,热点区域集中在县域中部林地及水域附近,冷点区域集中在南部草地及中心城区,冷点范围由于建设用地的扩张而显著增大。整体来看,1990—2020年霍山县生态系统服务价值降低,空间分布格局发生改变,未来应加强区域生态保护,提升用地集约化程度,防止建设用地无序扩张。

Abstract: Huoshan county is located in Dabieshan State Key Ecological Functioning Area, where is of significance to study its ecosystem services value changes on regional economic development and eco-environmental protection, and on regional economic planning and land allocation optimization. This paper, based on Huoshan's 1990 to 2020 land use data, uses RS and GIS to establish a Thornthwaite Memorial Climatic Production model via China's 2008 land ecosystem services value coefficient, with which Huoshan's eco-system servicing value coefficient is calibrated. Impacts of land use transformation on its ecosystem services value are analyzed over land use changing rate, direction and utilization degree with results discussed on spatial auto-correlation and hot-cold points. During 1990 to 2020, Huoshan's land use change is slow, but fast in construction and farm lands up to 402.58% and -5.13%, respectively. Regarding land transformation, forest land contributes the most in exports and construction land contributes the most in imports. Land use comprehensive changing index is over 0, suggesting a developing period of countywide land use. Huoshao's ecosystem services value has declined over the past three decades, most from forest land. Its spatial pattern displays a conspicuous spatial auto-correlation with hot spots focusing on forest and water lands, cold spots on southern grass land and downtowns, expanding with construction lands. This paper presents approaches to regional ecological protection, land extensive use and land disordered expansion.

Key words: ecosystem services value, land use, spatial analysis, Huoshan county
