受人类活动与社会经济发展的影响，湖北省部分河流出现水资源短缺，水环境恶化、水生态退化趋势，以上问题已严重威胁人类的生活和社会经济的可持续发展。以湖北省典型河流为研究对象，在流速法的基础上考虑环境流量指数因素，计算河流生态需水，并联合Tennant法生态需水计算结果，对二者结果进行综合考虑，确定综合条件下的生态需水量，为改善河流生态环境提供技术支撑与参考。
Abstract
Influenced by human activities and social economic development, some rivers in Hubei Province are suffering from water shortage, water environment deterioration and water ecological degradation, which have seriously threatened the sustainable development of human life and social economy. A typical river in Hubei Province is select as the research object and the river ecological water requirement is calculated based on the velocity method and environmental flow index factors are considered. The results of the velocity method and the Tennant method are considered synthetically to determine the ecological water requirement under comprehensive conditions. The conclusion provides technical support and reference for the improvement of river ecological environment.
