摘要

[目的] 识别汉江流域水源涵养关键生态修复区，进行植被优化配置和生态修复效果的验证，为生态修复工程实施范围提供科学依据。[方法] 主要利用InVEST模型，估算2020年水源涵养量，通过水源涵养功能强弱识别关键生态修复区，将水源涵养弱功能区内有林地、灌木林、草地、未利用地和25°坡以上的耕地区域作为修复区，对修复区进行林地适宜性评价，依据林地适宜性评价结果完成各土地覆盖类型之间的优化配置，模拟完成配置后修复区的水源涵养功能，并与配置前进行比较。[结果] 植被优化配置后，修复区产水量降低了6.97%，水源涵养总量提高了14.96%。[结论] 汉江流域通过植被优化配置手段提升水源涵养功能具有一定的潜力，未来应在水源涵养功能的基础上同时考虑其他生态服务功能，进行汉江流域修复区识别，以便采取更全面的修复措施来解决汉江流域的生态问题。

Abstract

[Objective] The key ecological restoration areas for water conservation in the Hanjiang River basin were identified

and the allocation of vegetation was optimized

and to verify the effects of ecological restoration was verified in order to provide a scientific basis for the implementation of ecological restoration projects.[Methods] The InVEST model was used to estimate the water conservation amount in 2020

and the key ecological restoration areas were identified according to the strength of the water conservation function. The ecological restoration scope was defined as the area with forest land

shrub forest

grassland

unused land

and cultivated land with slopes greater than 25° in the weak water conservation function area. A forest land suitability evaluation was carried out at the restoration area. The optimal configuration between land cover types was simulated

and the water conservation function of the restoration area after the configuration and completed was compared with the water conservation function before the configuration.[Results] Water production in the restoration area decreased by 6.97% after the optimal allocation of vegetation

and the total amount of water conservation increased by 14.96%.[Conclusion] The Hanjiang River basin has potential to improve water conservation by means of vegetation optimization allocation. In the future

the restoration area of the Hanjiang River basin should be identified by considering other ecological service functions on the basis of water conservation

and more comprehensive restoration measures should be taken to solve the ecological problems of the Hanjiang River basin.
