摘要
本文在分析乌头和附子的生态要求及其主要分布产区的气候环境的基础上,根据模糊集合论(Fuzzy sets)分别建立乌头和附子5个生态气候要素的隶属函数模型,以50个市(县)气象台(站)为代表,综合评价了四川省乌头和附子产地气候条件的生态适宜性;根据综合评判结果,分别将四川划分为3个乌头不同适宜区和4个附子不同适宜区。
Evaluting on the ecological adequacy of producing area is a fuzzy problem that is rather hard to handle. By Fuzzy Sets,the mathematical models of 5 main climatic factors about Wutou and Fuzi were built on their ecological charactersties and the climatic analysis of their principal producing areas;then eaculating the mod- el-value of 50 city's or county's climatic stations,Sichuan is seperately divided into 3 regions for Wutou and 4 for Fuzi in different climatic adequate degree by Fuzzy Synthetical Evaluting.This paper has provided a important basis for the rational productive distribution and a new mathod for evaluting the adequacy of the producing areas of Chinese Materia Medica.
