The Research On Assessments For Fishery Eco-environment And Its Application Illustrated With Chaohu Lake

Fishery is a renewable resource. It is unexhausted only when properly utilized. The resistant and healthy development for fishery relies on sustainable resources of water environment. It will be helpful for preserving varieties of aquatic and prompting effectively the use of water eco-resources to study the assessments for fishery eco-environment and analyze the environment problems of fishery waters.With the analysis of fishery eco-environment, this work focuses on setting up multi-orientation assessment index system of fishery water quality and aquatic organism; establishing fuzzy assembling method and analytic hierarchy process with a view to the weight of related factors by using mathematic means; analyzing the fact of fishery eco-environment through investigating and monitoring the present condition of Chaohu Lake waters; analyzing and assessing the measured data of the organism and water quality of Chaohu Lake using fuzzy comprehensive assessment method; testing and verifying the comprehensive analytic method of multiple assessment index systems, which can reflect the condition of fishery waters.This paper assesses Chaohu Lake fishery environment using the comprehensive analytre assessment method through monitoring the Chaohu Lake fishery environment of organism and water quality and this work analyzes Chaohu Lake fishery environment and poses the measurement and suggestions about harnessing environment.
