本文在对紫胶产区进行调查的基础上,分析了云南紫胶虫最佳生长地的植被条件、对其中的四种群落类型从植物种类成分、群落结构和群落生态等方面进行分析。根据丰富的寄主资源和有利于紫胶虫越冬的气候条件指出“暖热性稀树灌草丛”及“河谷季雨林次生林和灌丛”是云南紫胶虫及其主要寄主植物的适生类型。本文在总结紫胶产区的经验基础上,提出了开发利用的意见和改造的措施。

ON THE VEGETATION CONDITION OF THE BEST GROWING REGION OF LAC INSECT IN YUNNAN

Dalbergia obtusifolia, Dalbergia szemaoensis, Eriolaena spe-ctabilis, Ficus racemosa, Pueraria wallichii and Flemingia macrophylla are the best host plants of lac insect in Yunnan. According to investigation of regions producing lac, the vegetation conditions of the best growing regions of lac insect in Yunnan, especially relating plant community structure and community ecology in four of them. On the basis of abundant resources of these host plants and the climatic condition availing the overwintering of lac insects, the paper points out that "warm and hot savannah shrub and grass" and "valley monsoon forest and shrub forest" are the best type for the lac insect and its main host plants in Yunnan. On the basis of summarizing experience of regions producing lac, exploiting advices and transform's measure are put in the use of species and age of host plant, in the use of way and tensity.
