为了解临沧植烟土壤养分状况，测定了临沧烟区41个土壤样本的主要养分指标。根据模糊数学原理建立了土壤肥力指标，对临沧烟区土壤肥力进行了综合评价。结果表明：（1）临沧烟区土壤养分地区差异较大，各县（区）pH、氯离子隶属度均小于0.6；（2）临沧各县（区）土壤肥力指标为中级和较高两个等级；（3）以土壤肥力指标为基础，可将临沧烟区分为3类，第?类包括双江县、临翔区、沧源县；第Ⅱ类包括耿马县、镇康县、凤庆县；第Ⅲ类包括永德县、云县。综合考虑，临沧适合烤烟种植，同时适当增施氯肥和有机肥。

To understand the soil fertility status in Lingcang, Yunan province, the major nutrient contents of 41 soil samples from Lingcang tobacco-growing was determined, and soil fertility index(CCI) was established by using fuzzy mathematics. The results showed that soil nutrient contents varied much among counties in tobacco growing areas, the membership degrees of pH and chloride were less than 0.6;The CCI in Lincang could be classified into middle and high groups. Based on CCI, Lincang tobacco-growing areas could be classified into 3 groups. The group A included Shuangjiang County, Linxiang District, and Cangyuan County. The group B included Gengma County, Zhenkang County, and Fengqing County. The group C included Yongde County and Yun County. Overall, Lincang is suitable for flue-cured tobacco planting, but chloride fertilizer and organic manure are desired.
