[目的]研究地形对红花木莲分布的影响,筛选其适生条件.[方法]在腾冲市界头大营林区红花木莲分布区随机布设27个样地,研究其盖度和显著度与海拔、坡向、坡度、坡位、土壤类型5个地形因子的关系.[结果]影响红花木莲分布的主要地形因素为土壤类型、海拔,红花木莲的适生海拔为1 800~2 300 m,坡度为20 °左右.红花木莲的分布与坡向和坡位差异不显著.[结论]该研究可为提高红花木莲造林质量提供科学依据.%[Objective]To study the influence of topography on distribution of Manglietia insignis and screen its suitable conditions.[Result]Randomly deployed 27 plots in Manglietia insignis distribution area of Jietou camp forest in Tengchong City, the relationship between coverage and significant degree with altitude, slope direction, slope, slope position, soil type, topography was studied.[Result]The main influence factors for the distribution of Manglietia insignis were soil types and altitude, and the suitable elevation was 1 800~2 300 m, slope was 20 °.There was no significant difference between slope direction and slope position of distribution of Manglietia insignis.[Conclusion]The study can provide scientific basis for improving the quality of afforestation of Manglietia insignis.
