Abstract

Abstract: The water-level-fluctuation is a wetting and dryingarea,which is a section of special region caused by reservoir dispatch.It appears ecological fragility because of the water level repeatedly periodic variation alternation.According to the status of the Qingshitan reservoir,the paper first analyzes theecological fragility and its impact factors,then uses analytichierarchy process (AHP) to rank the response index,and finally reaches the conclusion that the key problems are the population complexity and vegetation coverage,which meansthe primary problems of the ecological restoration are its biodiversity and plant repair.

Key words: water-level-fluctuation, ecological fragility, impact factor, biodiversity, Qingshitan reservoir
