A Survey of Wild Plant Resources and Their Landscape Value in Baishiling Ridge in Hainan
-
摘要: 采用路线与样方调查相结合的方法,对海南琼海白石岭地区的植物物种组成进行了调查,结果表明,该地区植物共736种,隶属149科471属,具有观赏价值的野生园林植物资源约370种,隶属118科249属,包括海南特有种21种,珍稀濒危保护植物24种。分析该地区野生植被类型组成发现,鸭脚木(Schefflera octophylla)、荷木(Schima superba)、山油柑(Acronychia pedunculata)、黄桐(Endospermum spp.)、黄杞(Engelhardtia roxburghiana)等植物作为优势种和常见种在群落中占有重要地位。笔者根据观赏特性及园林用途将白石岭野生植物分为观花、观果、观树形、垂直绿化和地被5类,依据不同观赏特性、抗性适应性和用途筛选出具有观赏价值和园林应用潜力的野生乡土植物,并为野生植物在该地区的保护开发应用提出建议。Abstract: A survey was made of the plant species composition in the area of Baishiling Ridge in Qionghai, Hainan by using a combined method of route and sample plots. The ornamental value of the plant species was evaluated with reference to the growth form, plant type and posture, as well as flower color and appearance of the plants. The survey showed that this area was boasted of 736 species of wild plants under 149 families and 468 genera, of which about 370 species were wild landscape plants with ornamental value and belonged to 118 families and 249 genera, including 21 plant species endemic to Hainan and 24 species of rare and endangered plants. Analysis of the composition of wild vegetation types in this area showed that the dominant species and common species, such as Schefflera heptaphylla, Schima superba, Acronychia pedunculata, Endospermum chinense and Engelhardia roxburghiana, were important in the communities. The wild plants in the survey were classified into 5 groups: ornamental flower, ornamental fruit, ornamental plant appearance, vertical greening, and ground cover plant based on the ornamental features and use in landscape greening. Potential wild landrace plants with ornamental and landscaping value were selected based on their ornamental traits, stress resistance and adaptability and use purpose, and some suggestions were made on conservation and development of the wild local plants.
