对四川十九个站点影响锦橙生长发育的七项气候因素，以三十年（１９５１－１９８０年）的资料，用模糊数学方法进行综合评判，评价了本省各地适栽锦橙气候条件的优劣程度。结果表明，涪陵、江安、万县、宜宾、重庆等九地市为最适宜区；成都、乐山、南充等地市为适宜区；阿坝、甘改等为不适宜区。根据分析结果划分出了四川锦橙气候最适、适宜和不适宜三类生态区域。锦橙气候区划的模糊数学综合评价的关键步骤是各评判因素隶属函数的构造和权重的分配。
Seven climatic factors affecting the growth and development of Jincheng at 19 sites in Sichuan Province were evaluated with fuzzy mathematics based on the data of thirty years (1951-1980). The evaluation of the climatic conditions of Jincheng in different parts of the province was evaluated Poor level. The results show that nine cities such as Fuling, Jiang’an, Wanxian, Yibin and Chongqing are the most suitable areas; Chengdu, Leshan, Nanchong and other cities are the suitable areas; Aba and Gansha are not suitable areas. According to the results of the analysis, we classified the most suitable, suitable and unsuitable eco-regions for the Jincheng orange in Sichuan Province. The key step of the fuzzy mathematics comprehensive evaluation of the Jincheng climate division is the construction of the membership function of each factor and the distribution of weight.
