摘 要:三峡水库是我国特大型水利工程,水库蓄水运行后将出现一个落差达30m的涨落带,形成一类季节性的湿地生态系统。根据三峡水利工程的蓄水规划,探讨了在三峡水库运行过程中涨落带可能产生的一系列严峻生态与环境问题,如:岸边污染带的形成、可能诱发流行性病情和疫情的发生、涨落带的环境地质灾害加剧、涨落带生物多样性受损、生态系统更为脆弱等,并针对这些问题产生的原因、时空分布特征及趋势,提出了有针对性的防治措施。After the accomplishment of Threegorges reservoir, a 30 meters high waterlevelfluctuating zone (WLFZ) will appear along with the both banks, and become a kind of seasonal humid ecosystem. According to the program to store water of Threegorges reservoir, the ecological and environmental problems which will probably appear in WLFZ are discussed such as formation of contaminated zone along both banks, appearance of epidemic diseases in reservoir (including Chongqing urban districts), aggravation of geologic disaster, injury of biodiversity and intensifying of ecosystem fragile, etc. To counter the causes, distributed features and trends of ecological and environmental problems existing probably in WLFZ of Threegorges reservoir, the authors put forward six items of corresponding countermeasures.
