利用气候环境数据结合辣木8个生态适宜性气候指标,将云南划分出辣木种植的高适生区、低适生区和不适生区,并制作云南辣木适生区专题图。结果表明,云南辣木适生区分布于北纬25°以南海拔1 600 m以下地区和金沙江海拔1 600 m以下峡谷。辣木在云南普洱市、西双版纳州、红河州、临沧市、德宏州等11个州(市)有高适生区面积37 110 km2,占云南省国土面积的9.5%;在全省15州(市)有低适生区面积69 036 km2,占云南省国土面积的16.3%。云南辣木适生区多为干热河谷、山区丘陵,生态环境恶劣,经济落后地区。研究结果将为云南辣木科学种植提供参考。
Using climate data and 8 ecological suitable climate indicators of Moringa oleifera, the ecological region in Yunnan is divided into 3 types including high suitability, low suitability and unsuitability areas, and the the- matic map is made. The results show that the suitability areas of M. oleifera in Yunnan are located in the area with the south of latitude 25° and elevation below 1 600 m as well as the Valley of Jinsha River with the elevation below 1 600 m. There are 37 110 km2 high suitability area in 11 prefectures (cities) such as Pu' er, Xishuangbanna, Honghe, Lincang, Dehong , accounting for 9.5 % of the total land area of Yunnan. There are 69 036 km2 low suitability area in 15 prefectures (cities), accounting for 16.3 % of the total land area of Yunnan. Most of suita- bility areas lie in dry-hot valley, mountains and hills with poor ecological environment and economically backward regions. The research results could provide the reference for scientifically cultivation of M. oleifera in Yunnan.
