重楼资源分布与可持续利用研究进展

Research Progress in Resources Distribution and Sustainable Utilization of Rhizoma Paridis

重楼属植物在我国分布有19种18变种,主要分布在云南、四川、贵州、湖北及甘肃等地区,分布较广的品种是七叶一枝花和滇重楼。重楼的生长环境遭到破坏、资源分布破碎化,植物繁殖率低,资源再生较慢,各产区药材蕴藏量普遍下降,部分品种已濒临灭绝。而且重楼生态环境和自身遗传特性等原因会导致其进化和演变的程度发生变化,重楼物侯学及其它特征也会存在着细微的变异。需要对重楼野生资源进行有效保护,加快人工规范化种植,重视组织培养研究,采用保护与利用相结合,当前与长远相结合,多手段、多途径结合保证重楼资源的可持续利用,实现生态效益、经济效益和社会效益的高度统一。

There are 19 species and 18 varieties ofparidis genus plants in our country. The main producing areas are Yunnan, Si- chuan, Guizhou, Hubei, Gansu and so on. There is a wide distribution of Paris polyphylla Smith var. chiaensis （ Franch. ） Hara. and Paris polyphyUa Smith vat. yunnanensis （ Franch. ） Hard. -Mazz.. However, because the growth environment is being damaged, the resources distribution is scattered, the plant reproduction rate is low, and the renewable resources become more slowly, the reserves of Paris polyphyllas are generally declining in every region, even some of them are on the verge of extinction. The ecological environment and their own genetic traits of Paris polyphyllas can cause evolution and the change in the degree of evolution. Their phenology and other features also have some slight variation. Thus there is insistent demand to protect wild resources of Paris polyphylla effectively, accelerate artificial standardized planting and pay more attention to the tissue culture study. Combined protection with exploration and development with utilization, bonding current status with prospect and multiple approaches, we can ensure the sustainable use of Paris polyphylla resources and achieve a high degree unity in ecological, social and economic.
