河池市兜兰属植物资源及其保护利用初探

A Preliminary Study on Strategies of Protection and Utilization of Paphiopedilum Genus in Hechi

在查阅有关资料的基础上,采用样线调查和群落生态学相结合的调查方法,对河池市范围内兜兰属植物的分布数量和生境特征老蚌生珠调查分析。结果表明:河池市兜兰属植物资源丰富,共有6种兜兰属植物分布于全市10个县市区,但分布极不均匀;兜兰属植物生长于河池市石灰岩山地的常绿落叶阔叶林下的岩壁缝隙腐殖土上,所处环境条件脆弱,兜兰植株对环境的依存程度高;特殊的生物学特性、生境的丧失和过度采挖的其致濒的主要原因;在调查分析的基础上,提出了河池市兜兰属植物的保护利用对策。

On the basis of available references, combining the methods of line transect sampling and community ecology, number distribution and habitat characteristics of wild plantresources, Paphiopedilurn genus within Hechi area were studied. The results showed that there were total six species distributed across the range research area including 10counties. There were considerable rich resources in the field, and the number distribution of resources were not non-homogeneous. Most species within Paphiopedilum genus mainly grew at humus soil of rock crack in evergreen broad -leaved forest from limestone mountain region. The environmental conditions of these plant species were very fragile. The reasons of causing these plant resources to be endangered species mainly were due to their high dependance on environmental conditions, species-specific characteristics, habitat loss and overexploitation. Combined to as mentioned above,some strateuies of protection and utilization of Paphiopedilum genus were put forward.
