摘要: 气象条件是影响大闸蟹生长及产量的重要因素。本研究利用大闸蟹产量数据,结合1991—2023年兴化国家气象站逐日气象数据,分析影响大闸蟹产量的关键生长期和关键气象因子,确定大闸蟹气候品质指标,利用主成分分析法计算各指标权重,构建大闸蟹气候品质评价模型,并对气候品质等级进行划分,开展大闸蟹气候品质评价。结果表明:基于气候品质指标的大闸蟹气候品质评价模型,模拟结果能够定量化地反映气象条件对大闸蟹品质的影响,与同期大闸蟹规格等级对比,气候品质评价结果与大闸蟹规格品质具有较高吻合性,进一步验证了气候品质评价模型的可靠性。研究以期为兴化大闸蟹气候品质认证提供技术支撑。

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.
