辣木作为新中药资源，被广泛应用于植物医药。收集了全球960条辣木分布记录，结合气候、土壤、地形和太阳辐射空间协变量，采用空间信息技术与数据驱动模型，评估了辣木全球环境适宜性空间分布状况。结果表明，全球适宜种植辣木的土地资源总量约为3.61×109hm2，主要分布在北美洲南部、南美洲东部和北部、非洲中部、亚洲的东南部及大洋洲北部地区。

As a new Chinese medicine resource, Moringa oleifera Lam. is widely used in botanical medicine. To avoid economic losses caused by blind expanded introduction and cultivation it is urgent to evaluate the spatial distribution of land resources suitable for Moringa oleifera Lam. In this study, 960 global distribution records of Moringa oleifera Lam. are collected to assess the spatial distribution of global environmental suitability of Moringa oleifera Lam. by using spatial information technology and a data-driven model of spatial co-variables of climate, soil, topography and solar radiation. The results show that the land resources suitable for the cultivation of Moringa oleifera Lam. are about 3615.96 million hm2 in the world, which are mainly distributed in Southern North America, Eastern and Northern South America, Central Africa, Southeast Asia and Northern Oceania. This study provides a solid foundation for the cultivation partition and promotion program of Moringa oleifera Lam. and helps to alleviate the over-mining of moringa and solve the contradiction between supply and demand of Moringa oleifera Lam.
