摘 要：
Building ecologic and clean-type small watersheds proceeding from beginning with optimized land use allocation is of an important way to protect regional water and land resources and prevent and control the deterioration of ecologic environment. The paper discusses the necessity and feasibility of ecologic rehabilitation to be conducted in the upper stream, ecologic treatment in the middle reaches and optimizing land use allocation and ecologic protection in the lower reaches and; puts forward a new idea of improving the ecologic compensation within the river basin based on the interrelation established between "three lines of defence" of small watersheds and regional water and land resources and from angles of the present status of land use and spatial difference of social development of small watersheds.
