Resource Distributions and Environments of Wild Malania oleifera in Typical Distribution Areas of Baise
摘要
Abstract
In order to provide scientific basis for cultivation planning and industrial development of Malania oleifera,typical distribution areas of M.oleifera in Baise were investigated by using transect and sample plot methods.Combined with digital elevation model and meteorological data,kernel density estimation and box plot analysis were employed to explore plant characteristics of M.oleifera,differences of topographies,temperatures and precipitations in its distribution areas.Results showed that in Baise,M.oleifera distributed from dry-hot valley of Youjiang River to edge of Yunnan-Guizhou Plateau and from non-karst rocky desertification areas to karst rocky desertification areas.M.oleifera in two of its historical distribution areas was discovered.M.oleifera populations were found to be in good growing conditions.Suitable distribution areas for M.oleifera in Baise were regions with altitude of 582.58-1 106.73 m,annual mean temperature of 16.17-19.86℃and annual mean precipitation of 1 253.61-1 353.76 mm.Youjiang district and Tianyang district shared similar characteristics of relatively low altitude,relatively high annual mean temperature,relatively abundant and evenly distributed pre-cipitation.In Youjiang district and Tianlin district,M.oleifera primarily distributed on sunny slopes.In Lingyun county and Tianlin county,M.oleifera adaped to environmental differences between two sites and main-ly distributed on semi-shady slopes.Leye county was characterized by relatively high altitude,relatively small relief amplitude,relatively low temperature,relatively less precipitation and relatively large seasonal tempera-ture differences.In Leye county,M.oleifera primarily distributed on shady slope.关键词
