摘要
贵州亚热带地区共有 93种稀有濒危植物。其中 ,具有较高经济价值的松科、木兰科、棕榈科、金缕梅科 4个科植物略占 1 /3 ;以森林为生境的稀有濒危植物占 3 1 50 % ;因生境破坏而受到威胁的植物达82 80 %。表明人类干扰是贵州亚热带地区植物受威胁的主要因素 ,保护生态环境成为保护贵州亚热带地区稀有濒危植物的主要途径。根据区内的资源现状 ,可将该区的稀有濒危植物分为 5个保护等级 ,其中 1 0种为优先保护对象。
Of the 93 species of rare and endangered plants in the subtropical area of Guizhou Province, 1/3 belong to the four families of Pinaceae, Magnoliaceae, Palmaeceae and Hamamelideceae which have relative high economic values; 31.50% of the rare and endangered plants take forests as habitats; and 82.80% of the plants are threatened due to destruction of their forest habitats. This showed that human disturbances constitute the principal factor threatening subtropical plants in Guizhou and eco-environmental protection has become an effective way to preserve rare and endangered plants in the region. According to current resources situation, the rare and endangered plants in the region can be divided into five grades for protection. Of them 10 species endemic to Guizhou are given first priorities for protection and effective measures should be taken in action.
