The effective public participation is the key aspect of successfully integrated basin management.This article focuses on public participation in the basin management,and takes Baiyang Marsh basin as a case study.It simultaneously considers the dual factors:"the spatial level" and "the related benefit",and analyses the stakeholders of basin management.It also affirms the importance of ecology-residents in the basin area,because the residents in the ecological sensitive area not only understood the local ecology background extremely,but also they were the direct victim.On the other hand,their behavior would directly affect the basin environment.Therefore,the residents in the ecological sensitive area have a big influence with the implement of basin decision-making.Environmental awareness of ecology-residents and the way of public participate are actually the weak links of basin public participation.This paper proposes to take the ecology sensitive area as the core,integrate the overall resources in the basin area,and input the information and strength of each level in basin area,in order to promote the public participation in the ecological sensitive area.Through the "inputting" process,we can hold the ecology characteristic of the ecology sensitive area,use the process of public participation in other interest groups of other levels,and promote the implement of public participation in the whole basin.It also proposes to promote making the law and detailed regulations of basin public participation through the practice of public participation,in order to give legal guarantee to the basin public participation.
