Research on Drawing of River Aquatic Habitat Suitability Distribution

Habitat suitability distribution map is of great guiding significance for the understanding and protection of specific biological and ecological habitat. River corridor aquatic habitat distribution has the characteristics of linear and amphibious alternate. In drawing habitat distribution map, consideration should be given to combination of GIS spatial analyzing ability and aquatic habitat conditions simulation. This study presents the idea and method of drawing aquatic habitat suitability distribution, taking Taipu River in Taihu Lake basin as an example, analyzes the distribution characteristics of aquatic biology, using flow numerical simulation to analyze river water level and flow velocity, extracts aquatic habitat suitable conditions, combing with GIS and riparian land use, draws the aquatic habitat distribution map, to provide reference for the Taipu River management.
