湖南野生木本观赏植物资源及利用

湖南有维管束植物5500余种(含变种,下同)，其中野生木本观赏植物1200余种。笔者根据湖南木本观赏植物自然分布规律．将湖南野生木本观赏植物划分为4个类型．即中温型、低温型、耐寒型、广温型。对湖南主要的野生木本观赏植物如针叶类(39种)、茶属(31种)．冬青属(68种)、兰花类(86种)、杜鹃花属(54种)、槭树属(42种)等种类较多的类群进行了探讨，并对它们的观赏特性、抗寒性和选育潜力也进行了研究．提出了开发利用的建议。

The Study on Utilization of Wild Woody Ornamental Plant Resources in Hunan

There are more than 5 500 species of vascular plants in Hunan,including wild woody ornamental plants 1 200 species. According to the distribution regularities of woody ornamental plants nature in Hunan,wild woody ornamental plants are divided into four types: moderate temperature type, low temperature type, freezing resistance type, expand temperature type. Primary wild woody ornamental plants in Hunan as needle genera(39 species), Camellia(31 species),Ilex(68 species),Rhododendron(54 species),Maple(42 species) etc. are discussed. And those species with special ornamental traits, exploitation value,cold resistance and breeding potential are described emphatically. The paper put forward some suggestions for exploitation and utilization of the wild woody ornamental plants.
