基于AHP的模糊综合评判在茶叶气候种植区划中的应用

以信阳毛尖绿茶种植区划为例，运用层次分析法（AHP）确定区划指标的权重，结合模糊综合评判方法，计算出模糊隶属度，并对模糊隶属度进行加权平均，最终得到综合区划指标，从而对信阳毛尖绿茶种植区进行合理的农业气候种植区划。区划结果表明：信阳、固始、商城、新县、鸡公山等地综合指标值大于等于0.60，属于适宜种植区；罗山、光山综合指标值在0.45~0.59之间属于次适宜种植区，该区域信阳毛尖绿茶种植面积较大，但品质略逊于适宜种植区；息县、淮滨、潢川综合指标值小于0.45，属于不适宜种植区，该区域茶叶种植面积小，生产的茶叶品质较差。

Application of AHP Based Fuzzy Comprehensive Evaluation in Climate Regionalization for Tea Planting

Taking the planting area of the tea Xinyang Maojian as an example, using the Analytic Hierarchy Process (AHP) to determine the zoning index weight, combined with the fuzzy comprehensive evaluation method, the fuzzy membership function and the fuzzy membership of the weighted average are calculated, and then the comprehensive regionalization index is obtained, thus to conduct the agricultural climate regionalization of the tea planting area. The results show that the comprehensive indexes in Xinyang, Gushi, Shangcheng, Xinxian, Jigongshan Mountain, etc., are greater than or equal to 0.60, belonging to the suitable planting area; those in Luoshan and Guangshan are between 0.45 and 0.59, belonging to the sub suitable planting area, in which the planting area of Xinyang Maojian is large, but the quality is slightly inferior to the suitable planting areas. Xixian, Huaibin, and Huangchuan, with index value being less than 0.45, are not suitable for planting tea, in which the tea planting area is small, and the tea quality is poor.
