摘要
水电工程的建设运行会对周边生态环境造成不同程度的影响.以江西省最大的赣江流域为例,根据栋背水文站实测径流资料计算各类别的水文改变指标(IHA),结合变异范围法(RVA),分析并评估万安水库建设运行对流域水文情势的影响.结果表明,万安水库施工运行后综合改变度为49.24%,属于中度改变.
Hydropower project construction operation will have a negative impact on the surrounding ecological environment. Taking the biggest rivers in Jiangxi province,the Ganjiang river basin as an example,the Indicators of Hydrologic Alteration(IHA)at different stages are calculated according to the measured runoff data of Dongbei hydrological station,and the Range of Variability Approach(RVA)is used to analyze the influence of the construction and operation of Wanan reservoir on the hydrological situation of the river basin. The results show that the comprehensive change degree of Wanan reservoir is 49.24% after operation,which is a moderate change,therefore,the degree of influence on the downstream hydrological situation is moderate.
