Evaluation of Aquaculture Water Quality Based on Improved Fuzzy Comprehensive Evaluation Method

The quality of aquaculture waters is directly related to water management and efficiency, which puts forward higher requirements for evaluation. Based on the consideration influence temporal spatial changes quality, this paper proposed an improved fuzzy comprehensive evaluation method Specifically, constructing a new membership function in first place, then selecting dissolved oxygen, pH, temperature ammonia nitrogen content as indexes aquaculture, after that, collecting 60 sets index different seasons past three years, finally, evaluating Yangjiabo Aquaculture Base. Meanwhile, comparing it with results single factor traditional method. show that Base at worst level winter, has significantly spring, summer autumn. Compared other two method, can comprehensively reflect time space, more practical, so be considered provide scientific basis efficient classification.
