湿地水空间效应

地球水资源短缺问题日益严重,直接影响自然与经济社会可持续发展.陆地健康水循环和水资源的再生是基于合理的水调节空间.湿地是不可替代的水调节空间,因湿地特殊的水理性质和特有的生物地球化学作用,使湿地具有显著的调蓄地表径流和水体净化功能.人类活动大量破坏湿地,使湿地水空间效应明显下降,极大地削弱了湿地水调节功能.就流域生态、生产、生活用水的协调与保证而言,其合理的湿地配置是解决这一问题的重要基础之一.

Hydrological Space Effects of Wetlands

Water resource shortage problem of the earth is getting more and more serious, which directly influences the sustainable development of the nature, economy and society. The healthy water circulation and water resource regeneration are based on the rational water space for regulation. Wetlands are irreplaceable spaces of water regulation and have prominent functions of regulating and storing surface runoff and purifying water body due to their special water-physical property and characterized biogeochemical function. Human activities have destroyed a large number of wetlands, that made hydrological space effects of wetlands obviously drop and greatly weakened water regulating function of wetlands greatly. Rational collocation of wetlands in a basin is one of the important foundations in harmonizing and guaranteering water use for ecology, production and living in the basin.
