摘要
三峡大坝建成后 ,由于水位的自然涨落 ,将会在库区两岸形成两条平行的永久性的消落带 .消落带湿地是湖水水生生态系统与湖岸上陆地生态系统的交替控制地带 ,该地带具有生物的多样性、人类活动的频繁性和生态的脆弱性 .随着人类活动的影响 ,已成为湖岸带中生态最脆弱的地带 ,并严重制约着库区周围环境的演替和发展 .因此 ,必须针对消落带地区的特殊情况 ,选择适当的模式对消落带进行环境整治和保护 。
Two parallel permanent fluctuating belt will be formed along the two banks of the reservoir because of the natural fluctuation of water level after the finish of the Three Gorges Dam. The wetland of fluctuating belt is the place occupied alternately by lake water eco-system and land eco-system. This place, featured by biological variance, frequency of human activities and the ecological frailty, has become the most frail eco-belt by the lake and seriously inhibits the environmental succession and development around the reservoir region. Therefore, it is essential to choose proper model to renovate and safeguard the environments of the fluctuating belt and realize the restoration and reconstruction of eco-system of the reservoir region, with regard to the special conditions of the fluctuating place.
