水资源的赋存需要特定的空间结构,水空间对于维系水资源系统的完整性、保障水循环和水资源的可再生能力、实现水资源的可持续开发利用具有重要作用。 由于人类活动极大地干扰了地球表层系统,水空间结构遭到严重破坏,破坏了水资源支撑社会经济发展的可持续能力。水空间的丧失极大地改变了流域尺度上的水循环过程,加剧了水资源的负均衡性。科学规划水空间,建立水资源安全的水空间格局和预警系统,以实现水资源的可持续性利用,保障资源、环境与社会经济协调发展。
Special space is required for storing water resources. Space for water plays an important role in keeping integrity of systems of water resources, ensuring water cycle and regeneration and realizing sustainable development of water resources. The space for water is composed of spaces of many media related to water, such as forest, wetland, flood plain, soil and underground media contained water. Because human activities violently disturb the systems of the global surface, structure of space for water is damaged severely, which harm sustainability of water resources. Loss of space for water changes the processes of water cycle and aggravates negative equilibrium largely. Through scientific plan of space for water, the pattern and forecast system of space for water are set up in order to realize sustainable utilization of water resources and ensure harmonious development of resources, environment and social economy.
