Abstract:

A comprehensive quantitative method for the evaluation of fishery feasibility of Lihu was established based on the techniques of principal components analysis,analytic hierarchy process and geographic information system.12 factors have been screened according to the environmental and hydrological conditions of Lihu lake and were divided into 4 submodels.The evaluation map of fishery feasibility in Lihu lake was achieved after the process of each indicator’s weight calculation and spatial analysis accomplishment.The results indicated that: 5 grades of fishery feasibility of Lihu lake termed as highest,higher,high,general and low were 06408,23229,38448,11214 and 0.0801 km2,respectively.The study provided reference for plan and management to administrative department.
