Abstract

Abstract: The real data of river crab production from 2010 to 2019 in Xinghua City, Taizhou were selected, the membership function was designed by using fuzzy mathematics theory, and the “trial and error” and normalized processing method were adopted to statistically analyze and associatively study the influence of different weather meteorological factors （high temperature days, continuous high temperature frequency, rain days, continuous rain frequency, short sunshine days, continuous short sunshine frequency） on river crab production indices （yield per unit seedling amount, survival rate）. The results showed that overcast and rainy weather had a great impact on the actual production of the river crab, while the negative impact of high temperature weather was weakened due to the intervention of human measures. Based on the research results, a weather index insurance product for the river crab （high temperature index, rainy index, overcast index） was designed, in order to promote the development of agricultural meteorological index insurance work in Taizhou City, and provide a pilot scheme for Jiangsu Province and even the national aquatic meteorological insurance business.

Key words: river crab, meteorological factors, weather index, agricultural insurance, Xinghua City
