水域空间承载力研究进展

Review of research on water space carrying capacity

水域空间是水循环的重要场所,具有供给水资源、调节局地气候、行洪除涝、维护生态系统平衡和多样性等多种生态服务功能,对“经济社会-生态环境”复合系统的协调发展有重要的承载作用。从水资源承载力的空间角度,提出水域空间承载力的概念和内涵,进而从水域的空间组成和空间结构两方面综述水域对“经济社会-生态环境”系统的支撑作用。从学科发展和水域空间综合管理实践需求的视角出发,指出未来的研究方向:加强水域空间组成和空间结构联动影响的研究,建立水域空间承载力评价体系;优化研究方法,耦合水域空间承载力的量化研究方法;加强多时空维度耦合效应的水域空间承载力研究,为实现水域空间资源的可持续开发利用、全面提升水资源承载力提供管理决策建议。

Water space is where water cycles operate and circulate,it plays a critical role in the supply of water resources,regulation of local climate,control of flood and waterlogging,as well as the maintenance of ecosystem balance and diversity.It is crucial to the coordinate development of“economic society-ecological environment”combined system.In this paper,we put forward the concept and connotation of water space carrying capacity from the spatial perspective of water resources carrying capacity,and summarized the supporting roles of water space carrying capacity in the“economic society-ecological environment”system from two aspects of the spatial composition and spatial structure of the water space.With the consideration of discipline development and practical requirements of integrated water space management,the future research directions were pointed out as follows:water space carrying capacity evaluation system should be built based on the study of the linkage effects of the spatial composition and the spatial structure of water space carrying capacity;a coupled method of quantifying water space carrying capacity should be optimized and constructed;the research on water space carrying capacity of multiple spatiotemporal dimensions should be strengthened,so as to provide practical management and decision-making recommendations for the sustainable development and utilization of water space resources,as well as improve the carrying capacity of water resources in an all-round way.
