云南省双江县膏桐良繁基地近自然林业建设模式的初步研究

按照植被覆盖差异将云南省双江县膏桐良种繁育基地划分为落叶季雨林、季风常绿阔叶林及萌生灌丛、暖温性针叶林、热性稀树灌木草丛、人工林和农田6类立地类型。在此基础上,探索了基地建设的近自然造林模式,提出在膏桐种植中应当遵循促进生态恢复、保护生物多样性、保持群落结构完整性、充分利用现有物种、采用乡土物种和多物种混交等原则。

Preliminary Study on the Close-to-natural Forestry Construction Model of the Cultivation Base for the Improved Varieties of Jatropha curcas L. in Shuangjiang County of Yunnan Province

According to the difference of vegetation coverage, the cultivation base for the improved varieties of Jatropha curcas L.in Shuangjiang County of Yunnan Province was divided into 6 site types of deciduous monsoon forest,monsoonal evergreen broadleaved forest and the sprouted shrub,warm-temperate coniferous forest,hot shrub-grassland,artificial forest and cropland.On this basis,the close-to-natural forestation model of base construction was discussed.Several principles that should be followed were put forward such as promoting the ecological restoration,protecting the biodiversity,maintaining the stabilization of community structure,making full use of the existing species,planting mixed forest of native species and multiple species.
