Abstract: Fanhe River is one of the large tributaries, whose basin area is greater than 1 000 km², of the Liaohe River mainstream. It is one of the fourteen ecological demonstration areas whose tributaries influx into the mouth of Liaohe Conservation Area that are proposed to construct in the national “12th Five-year” period. Fanhe River is also a typical representative of constructing ecological demonstration area in Liaohe Conservation Area. This paper fully analyzes the current water environment, distribution of natural resources, objects of protection as well as the regional development in the demonstration area, based on which we put forward the idea of constructing ecological demonstration area in Fanhe estuaries. This ecological demonstration area is constructed in accordance with the mode of Wetland Park and regional leisure resort. The scheme designed 5 aspects of construction, including ecotourism, ecological agriculture, new rural area, wetland and green corridor. The design philosophy and ideas are referential to other ecological demonstration areas construction.
