摘要
海南昌江县燕窝岭石灰岩山体的主要植被型为热带半落叶季雨林。初步调查中发现了两种珍稀濒危植物,它们分别是海南椴(Hainania trichrosperma)与莲桂(Dehaasia hainanensis)。当地虽然仍然保留低地树林,但常被利用作采集柴薪与放牧。燕窝岭的岩洞也有被利用作采集燕窝与鸟粪。对燕窝岭自然资源构成最大威胁的是石灰岩开采。本文并对燕窝岭的自然保育与可持续利用提出了建议。
Yanwoling limestone area of Changjiang County,Hainan Island is mainly covered in tropical semi-deciduous seasonal forest with a diverse community.Two rare and endangered species were found during a brief survey,they are Hainania trichrosperma and Dehaasia hainanensis.Although the area still preserved a lowland forest community,it was frequently disturbed and utilized for fuel-wood collection and grazing. The caves at Yanwoling are also exploited for collection of guano and bird nest.The most destructive utilization of Yanwoling's natural environment was the mining of limestone for cement preduction,which would eventually completely destroy the biota of the area.Recommendations for future conservation and sustainable utilization of Yanwoling are proposed.
