Technology and Application of Climatic Quality Evaluation for Hairy Crabs
摘要
Abstract
The meteorological condition is an important factor affecting the growth and production of hairy crabs.The climatic quality index are determined by analyzing the key growth period and the key meteorological factors affecting the production of hairy crabs,combined with daily meteorological data from the Xinghua National Meteorological Station from 1991 to 2023.Using principal component analysis method,the weights of the climatic quality index are determined.The climatic quality evaluation model is established by using the weighted summation method,and the climatic quality index is calculated and graded to carry out the climatic quality assessment.The results show that simulative results of the climatic quality evaluation model based on the climatic quality index can quantitatively reflect the impact of meteorological conditions on the quality of hairy crabs.Compared with the specification grade of hairy crabs in the same period,the climatic quality evaluation results are highly consistent with quality of hairy crabs which further verifies the reliability of the climate quality evaluation model.The study provides technical support for climate quality certification of hairy crabs in Xinghua.关键词
