摘　　要：以南盘江江边街水文站为例,利用Texas法、Tennant法、月保证率法等,对维持生态环境健康的河道内生态环境需水量进行了研究。结果表明:南盘江江边街水文站高、中、低方案的年河道内生态环境需水量分别为6.613×10^(9)m^(3)、4.549×10^(9)m^(3)、2.486×10^(9)m^(3);高、低方案是所需生态流量的极限值,中方案是适宜流量的方案。开展本研究,对确定应留在河道内的水量,解决水生态问题,维护水生态系统健康发展,实现社会的可持续发展具有重要意义。Taking the Nanpanjiang River Jiangbianjie hydrological station as an example,eco-environmental water requirement in the river course to maintain a healthy ecological environment was studied with the Texas method,Tennant method,monthly guaranteed frequency method,etc.The results show that:the annual eco-environmental water demands of the high,medium,and low schemes of the Jiangbianjie hydrological station are 6.613×10^(9)m^(3),4.549×10^(9)m^(3),and 2.486×10^(9)m^(3),respectively.The high and low schemes represent the limit values of the required ecological flow;the medium scheme is a suitable flow plan.The research is conducted to determine the amount of water that should be keft in the river channel.It has great significance to solve ecological issues,maintain the healthy development of aquatic ecosystems,and achieve sustainable social development in the Nanpanjiang River basin.
