摘要
赤水河流域是长江上游重要的生态安全屏障,研究未来不同发展情境下赤水河流域的生态系统服务价值,对赤水河流域生态环境保护政策制定和环保措施布局具有重要意义。以赤水河流域为研究区域,利用FLUS(future land use simulation)模型和InVEST(integrated valuation of ecosystem services and trade-offs)模型,预测2040年赤水河流域在自然发展、环境保护和经济发展三种情景下,产水、土壤保持和水质净化等生态系统服务功能,并识别赤水河流域生态系统服务功能重点保护区。结果表明,农田和城镇在不同情景下变化较大,其中经济发展情景较自然发展和环境保护情景分别增加510.55 km^(2)和1 475.76 km^(2);环境保护情景下高产水功能(>700 mm)和高土壤保持(>2 000 t/hm^(2))的区域分别约占赤水河流域面积的36.81%和47.15%;合肥市辖区内的生态系统服务功能重点保护区占比最高达62.65%。研究结果以期为赤水河流域明确重点保护区域,推动实现空间精细化保护和管理提供一定的支持。
The Chishui River Basin has been recognized as an important ecological security barrier in the upstream of the Yangtze River Basin.Research on the ecosystem service value of the Chishui River Basin under different future development scenarios is of great significance to carry out the environmental protection policies and the environmental protection measures.Therefore,Chishui River Basin has been selected as the research area and the FLUS(future land use simulation)model and InVEST(integrated valuation of ecosystem services and trade off)model were functioned to predict the ecosystem services,including water yield,soil conservation,and water purification,under three scenarios,such as natural development,environmental protection,and economic development in 2040.The high ecosystem services functions in all three scenarios are identified as the key protected areas.The results show as follows.There are significant changes in agriculture area and urban area under different scenarios,especially,the agriculture area under the economic development scenario has increased 510.55 km^(2) and 1475.76 km^(2) compared to the natural development and environmental protection scenarios,respectively.In the environmental protection scenario,the areas with high water yield(>700 mm)and high soil conservation function(>2000 t/hm^(2))account for approximately 36.81%and 47.15%of the Chishui River basin area,respectively.The proportion of key protected areas for ecosystem services functions in the Zunyi City account for approximately 62.65%.The results of this study aim to provide certain support for identifying key protected areas in the Chishui River Basin and promoting the implementation of spatial refinement protection and management.
