云南干热河谷地区种子植物资源与开发利用初探

云南干热河谷植被均为耐旱的旱生植被，主要有以下三种类型：1）半稀树草原（Semi-savanna）型植被；2）肉质多刺灌丛；3）在金沙江上游滇西北的亚热带性的干热河谷地区分布着类似马基(Maquis-like）型的多刺小叶矮生灌丛。按其产物和用途可分为6类：药用植物、纤维植物、树脂和树胶植物、芳香油植物以及淀粉植物等。资源破坏性开发和环境的变化，使现存资源的保护和开发利用成为目前的主要问题。

An Exploration on the Resources and Development of Seed Plants in Dry and Hot Valley of Yunnan

The floristic characteristic of seed plants in the dry and hot valley of Yunnan is dry-fast,and there are three vegetation types:(1)The Semi-savanna; 2)the Maquis-like shrub;(3)The thorny succulent shrub.Classified by natural products and utilization they can be divided into 6 types:medicinal plants,oil plants,fibre plants,colophony and balata plants,perfume plants and amylum plants .Now ,the primary problem is how to protect,develop and utilize plant resources,because devastating development and the deforestation have destroyed the ecological environment and plant resource.
