Study on Water Storage Scheme For Cascade Dams Based on a Habitat Suitability Assessment Model
摘要
Abstract
For water-scarce northern rivers,cascade reservoirs are often constructed to impound upstream and inter-regional water,to restore and expand the flood storage area,wetlands,artificial lakes,and to restore the groundwater level in the basin to provide sufficient ecological water.In order to maximise the positive effects of damming on the survival of biological habitats,this paper takes six waterbird species in the Fen River Basin as the target birds,and selects the middle reaches of the Fen River gradient storage hydraulic dam as the research object,and makes use of the habitat suitability model to optimize the original design of the storage scheme,and puts forward the optimal storage scheme by considering the Weighted Usable Area(WUA)of the waterbirds'habitat on the basis of the guaranteeing effect of the water storage.The results of the study show that the optimized WUA during the dry water period is 37.1%higher than the original scheme,which can provide a wider range of suitable habitats for the migration of Fen River migratory birds in winter.The improvement of habitat suitability in the upstream section of the hydraulic dam control area was significant.Under the storage scenario corresponding to the maximum WUA,the high suitability area is mainly distributed in the middle and upper reaches of the pre-dam area.In order to enhance the universality of the optimal design of the water storage scheme of the terrace lock and dam,the numerical calculation results were combined to propose the improvement measures for the water storage scheme setting of hydraulic dams with different conditions.The results of the study can provide a reference for the hydraulic regulation of typical northern rivers with water shortage in the dry season.关键词
