三峡水库消落区对库区水土环境的影响研究

三峡水库投入使用后。在库区两岸形成周期性变化的水陆交错地带即消落区，它是陆地和水生生态系统的交错地带．具有生态脆弱性、生物多样性、变化周期性和人类活动的频繁性的特点，它对水、陆生态系统具有重要影响．通过调查消落区的类型、分布、面积等基本情况，从消落区水、土相互作用角度，分析了消落区在水、土交互作用下对水、陆生态系统的影响．提出了消落区生态保护的主要措施．

Effects of the Riparian Zone of the Three-Gorges Reservoir on the Water-Soil Environment of the Reservoir Area

After the Three-Gorges Reservoir was put into use, riparian zones have been formed on both sides of the reservoir where the water level changes periodically. This ecotone of overlapping water aquatic ecosystem and terrestrial ecosystem, owing to its characteristic ecological vulnerability, biodiversity, periodical fluctuation and high frequency of human activities, has a profound influence on the water aquatic and terrestrial ecosystems. The authors of this paper have investigated the types, distribution and area of such riparian zones and, from the perspective of water-soil interaction, analyzed the influences of water-soil interaction in the riparian zones on the water aquatic and terrestrial ecosystems there. Some countermeasures are proposed for the protection of the eco-environment in the riparian zones.
