基于种植区植被的膏桐混交模式选择研究

Study on Mixed Model Selection Based on Vegetation of Cultivated Area of Jatropha curcas

初步介绍了云南省双江县及膏桐(Jatropha curcas L.)种植区植被概况,并且对膏桐林混交物种选择、混交模式确定以及混农林业模式等进行了初步分析。结果表明,双江县自然植被可以划分为6个植被型,8个植被亚型,10个群系和13个群落;双江县膏桐种植区主要植被类型有热性灌丛、热性稀树灌木草丛、暖温性稀树灌木草丛和农地。并建议在双江县及相似地区造林中应采用适当的混交物种和混交模式,在农地上可以采用混农林业造林模式。

In this paper the vegetation of Shuangjiang county and the cultivated area of Jatropha curcas were introduced.And the selection of mixed species,the mixed model and the agroforestry model of J.curcas forest were analyzed.The result showed the vegetation of Shuangjiang county could be attributable to 6 vegetation types,8 vegetation subtypes,10 formations and 13 communities.And the vegetation of the cultivated area included in hot scrub,hot shrub-grassland,warmtemperate shrub-grassland and cropland.Then it was suggested that some mixed species and model afforestation was applied at shrub land and wild grass ground,and agroforestry model was applied at cropland.
