基于生态水文学理论的西北旱区水资源管理初探

The Research of Water Resources Management Based on Theory of Ecohydrology in Northwest Arid Region

水资源是制约西北干旱区社会经济发展,影响生态环境的关键因子,对本地区未来经济社会可持续发展起着显著的作用。目前的水资源管理多集中于可见的、可以被人类直接利用的蓝水资源,忽略了绿水资源的评价和管理。绿水是维持陆地生态系统景观协调和平衡的重要水源,在维持陆地生态系统生产功能和服务功能方面有重要作用。利用生态水文学原理可以积极地保护、维持和改善自然景观,指导生态环境脆弱地区的生态环境建设与水资源管理高效正确运行。本文在遵循生态水文学理论的基础上,提出兼顾生态和经济有序共生发展的水资源管理方法,以期为西北干旱区水资源管理提供理论依据。

Water Resources is the key factor restricting economic and social development and the ecological environment in northwest arid region, which plays a significant role in sustainable economic and social development in the future. The current management of water resources is more concentrated in blue water, which is visible and can be directly used by human beings, ignoring the evaluation and management of green water. Green water of terrestrial ecosystems is to maintain coordination and balance of the landscape important water source, and has an important role in sustaining production of terrestrial ecosystems functions and services functions. The use of ecological principles hydrology can actively protect, maintain and improve the natural landscape, and guide the ecological environment construction and water resources management in the fragile ecological environment. This paper, based on theory of ecohydrology, puts forward a water resource management method considering both ecological and economic development in order to provide the theoretical basis for water resources management in northwest arid region.
