摘要
美国灌溉—排水—湿地综合水管理系统(WRSIS)对我国农村实际情况有局限,目前我国研究中对WRSIS进行了修正。但对修正的WRSIS的研究主要集中在湿地系统水质的化验与分析方面,很少考虑湿地系统中存在土壤侵蚀对其净化水质效果的影响。现重点引进了水侵蚀预报模型(WEPPv2006.5),以在广西桂林进行修正的WRSIS试验研究为例,利用该模型模拟湿地系统土壤侵蚀等水文状况,以便进一步提高湿地系统净化水质的能力。
The utilization of a Wetland-Reservoir-Subirrigation Systems （WRSIS） developed by America is limited in China rural condition. The improved irrigation and drainage systems adapted to China have been designed. But studies of improved WRSIS were mainly focused on analysis and test of water quality of wetland systems, and seldom considered the influence on effect of purifying water quality in the systems under soil erosion. Water Erosion Prediction Project （WEPPv 2006. 5） is introduced and a case study of improved WRSIS in Guilin,Guangxi province is given in the paper by applying this model to simulate soil erosion and hydrology condition in wetland systems to further raise the ability of purifying water quality in wetland systems.
