Research on predictive distribution and planting GAP of Cyathula officinalis in China is helpful to provide scientific basis for its protection and planting popularization. According to the data in 63 distribution sites and 49 ecological variables, using MaxEnt ecological niche model and 3S technology, we performed a quantitative analysis of suitable distribution and planting GAP of C. officinalis in China. Our results show that: ① the area of suitable distribution of C. officinalis is about 634 385.80 km² in total, and mainly in Northeastern and Southeastern Sichuan, Northern and Southeastern Yunnan, Western and Southwestern Guizhou, Southwestern and Northeastern Chongqing, Southwestern Shaanxi, Southeastern Gansu, Western Guangxi, Southeastern Tibet. ② The main ecological factors determining the potential distribution are precipitation, altitude, minimum temperature of coldest month, soil type, monthly mean temperature. ③ The planting GAP region are mainly in Guangyuan, Mianyang, Ya'an, Leshan, Liangshan, Panzhihua of Sichuan province, Hanzhong of Shaanxi province, Dali, Nujiang, Chuxiong, Baoshan, Qujing, Wenshan of Yunnan province, southwestern autonomous prefecture in Guizhou province. The results are of great significance for realizing the growth environment, predicting the potential distribution and promoting planting popularization for C. officinalis.
中国川牛膝预测分布与种植适宜区研究有助于为其保护与种植推广提供科学依据。依据63个分布位点和49个生态变量的数据，利用MaxEnt生态位模型和3S技术，对中国川牛膝适宜分布与种植适宜区进行了定量分析。结果表明：①川牛膝适宜分布总面积约634385.80平方千米，主要分布在四川东北部和东南部、云南北部和东南部、贵州西部和西南部、重庆西南部和东北部、陕西西南部、甘肃东南部、广西西部、西藏东南部。②决定潜在分布的主要生态因子为降水量、海拔、最冷月最低温度、土壤类型、月平均温度。③种植适宜区主要在四川省广元市、绵阳市、雅安市、乐山市、凉山州、攀枝花市，陕西省汉中市，云南省大理州、怒江州、楚雄州、保山市、曲靖市、文山州，贵州省黔西南州。研究结果对了解川牛膝生长环境、预测潜在分布及推动种植推广具有重要意义。
