摘要
滇池流域内河流众多,为研究滇池流域的河流水生态状况,采用Tennant法和R2-CROSS法计算滇池流域河流生态需水量,进行对比分析。研究结果表明:使用Tennant法计算河流生态需水量为16974.59万m^(3),使用R2-CROSS法计算河流生态需水量为16715.49万m^(3)。Tennant法计算灵活、简单,R2-CROSS法综合考虑了研究河段的水力特性、生态特性和河道形态特性,计算结果更全面。研究结果可为滇池流域的水资源开发利用以及生态系统的保护和恢复提供科学依据。
There are many rivers in Dianchi Lake Basin.In order to study the ecological status of river water in Dian⁃chi Basin,the river ecological water demand of Dianchi Basin was calculated by Tennant method and R2-CROSS method,with the calculating results being 169.7459×10^(6)m^(3)and 167.1549×10^(6)m^(3) respectively.The calculation by Tennant method is flexible and simple.The calculation by R2-CROSS method takes into account the hydraulic char⁃acteristics,ecological characteristics and river morphological characteristics of the studied river section with the cal⁃culation results being more comprehensive.The results of calculation provide scientific basis for the development and utilization of water resources as well as the protection and restoration of ecosystem in Dianchi Lake Basin.
