Abstract

Fish growth evaluation and association degree analysis of fish growth and fish growth environment are important links of water body environment and biological comprehensive improvement. The fish growth evaluation and the association degree analysis of fish growth and fish growth environment in rivers and lakes have no uniform standard methods, most of the conventional evaluation of the fish growth rate adopts a qualitative method, and the method cannot quantitatively analyze the fish growth and the association degree of the fish growth and the fish growth environment. The method is a fuzzy substance element model and grey association degree analysis-based method, achieves quantitative analysis of the fish growth evaluation and the association degree of the fish growth and the fish growth environment, and has important practical significance for management of river basin fish resources.

Description

technical field [0001] The invention belongs to a method based on a fuzzy matter-element model and a gray correlation degree method, which analyzes the correlation degree between the growth suitability of fish and the growth environment of fish, and quantifies the suitability of fish growth and the growth environment of fish Correlation, analyze the quantitative relationship between fish growth and growth environment of various fish ages, and provide technical support for ecological environment protection and fishery resource management. Background technique [0002] Fish is a higher-level consumer in the lake ecosystem and has a close interaction with the lake environment. With the continuous deterioration of the environment, especially the aggravation of eutrophication, fish species in many lakes have decreased, and there have been phenomena of miniaturization, younger age, and miscellaneous fish (Huang Yuyao, 1993; Zhang Guohua et al., 1997). However, the catch compositi...
