摘　　要：目的:分析毛果木莲在我国适宜引种推广的区域及面积。方法:依据毛果木莲生长环境,运用层次分析法(AHP)确定9个生态因子的权重;通过地理信息系统(GIS)得到各生态因子的适生范围;此外对毛果木莲在全国引种推广的适宜区域进行分析和面积统计。结果:毛果木莲适宜在全国引种推广的总面积为1119070 km2,主要在云南、广西壮族自治区、贵州等18个省。结论:利用GIS和AHP对毛果木莲在我国引种推广的生态适宜性进行分析,为毛果木莲及其他极小种群野生植物(PSESP)的合理应用和保护提供了参考。Objective:To analyze the suitable regions and areas for the introduction and promotion of Manglietia ventii in China.Method:According to the growth environment of M.ventii,analytic hierarchy process(AHP)was used to obtain the weights of 9 ecological factors.The suitable range of each ecological factor was obtained through geographical information system(GIS).The suitable areas for the introduction and promotion of M.ventii seeds in the country were analyzed and the area statistics were analyzed.Results:The total area suitable for the introduction and promotion of M.ventii in China is 1119070 km2,mainly in 18 provinces such as Yunnan,Guangxi Zhuang Autonomous Region and Guizhou.Conclusion:GIS and AHP were used to analyze the ecological suitability of the introduction and promotion of M.ventii in China,which would provide reference for the rational application and conservation of M.ven⁃tii and other plant species with extremely small populations(PSESP).
