本文应用模糊集合理论对湘潭市1962～1985年双季稻气候产量初步探讨。试图揭示产量丰歉及气候年景好坏等没有明确外延的模糊概念,在隶属空间[0—1]上取值,用隶属函数量化出来,模糊概念就不模糊了。这样把隶属关系,由传统数学的二值逻辑的基础扩展到连续值上来,初步处理了上述模糊现象。本文所引用的产量数据和气候资料,分别由湘潭市农业局、气象局提供。采用笔算方法如下:
This paper applies fuzzy set theory to discuss the climate output of double crop rice in Xiangtan City from 1962 to 1985. Trying to reveal the fuzzy concept of no explicit extension such as the apology of production and the good or bad year of the climate, etc., which are valued in the membership space [0-1] and quantified by the membership function, the fuzzy concept is not obscured. In this way, the subordinate relations are expanded from the basis of the binary logic of traditional mathematics to continuous values, and the above ambiguities are dealt with initially. The production data and climatological data quoted in this paper are respectively provided by Xiangtan Bureau of Agriculture and Meteorological Bureau. Using pen calculation method is as follows:
