琼海市五园农村周边石墨矿区植被资源研究

通过对琼海市五园农村周边石墨矿区植被资源进行详细的野外调查与室内分析 ,结果表明 ,琼海市五园农村周边植被类型多样 ,结构和组成复杂 .在 2km2 的范围内 ,维管束植物多达4 18种 ,隶属 99科 ,311属 .其中蕨类植物有 8科 ,8属 ,11种 ;裸子植物有 2科 ,2属 ,2种 ;被子植物有 89科 ,30 1属 ,4 0 5种 .在这 4 18种植物中草本植物有 15 6种 ,藤本植物 70种 ,灌木植物 94种 ,乔木植物 98种 .生物多样性指数 (Shannon wiener指数 )较高 ,各植被类型分别为农村周边残次林(4 97)、橡胶林林下植被 (3 72 )、农田周边灌丛 (3 5 6 )、橡胶林周边灌丛 (4 2 6 )、桉树林林下植被(3 17)、桉树林周边灌丛 (4 78) .因此 ,无论从护村、生物多样性保护方面 ,还是从农村未来采矿后的生态环境恢复建设方面 ,对现有的植被资源都要给予充分的考虑 .

Study on the Vegetation Resourses of the Graphite Mine Area Around Wuyang Rural of Qionghai City

In this paper,through a detailed outdoor investigation and indoor analysis,the authors make a study on the vegetation resourses of the graphite mine area around Wuyang rural of Qionghai City.The results show that there exists a great diversity of vegetation types around Qionghai Wuyang,with a complex vegetation structure and component.Within an area of 2 sq.km.,there are 418 species of vascular bundle plants which belong to 311 genera,99 families.Among which,there are 11 species of pteridophyte which belong to 8 genera,8 families; 2 species of gymnosperm which belong to 2 genera,2 families;405 species of angiosperm which belong to 301 genera,89 families.Among the 418 species of plants,there are 156 species of grass plants,70 species of liana plants,94 species of shrub plants,and 98 species of arborous plants.The results also show that the bio diversity indexes of vegetation around the village are higher and the vegetation types mainly consist of residual secondary forest around the rural(4.97),vegetation under rubber tree(3.72),shrub around field(3.56),shrub around rubber tree(4.26),vegetation under eucalyptus forest(3.17),shrub around eucalyptus forest(4.78)The date in the blanks are Shannon wiener indexes].
