农村地区植被不同程度上都受人类生产活动影响.为了揭示琼东北农村地区森林植物区系特征,在搜集文献资料和样方调查基础上,对文昌、琼海的23个村庄周边森林植物资源进行分析.结果表明,琼东北农村地区森林植被主要有维管植物967种,其中蕨类植物39种,裸子植物4种,被子植物924种.科的分布区类型中单种科与寡种科占多数,特别是单种科比例较高,与尖峰岭的较为接近,比五指山高8个百分点,地理成分以热带一亚热带分布型为主.属的分布区类型中小属和单种属占绝大多数,占海南1 210属的45.62％,地理成分以泛热带植物分布为主.%The vegetation in northeastern rural areas of Hainan Island has been widely disturbed by human activities, and the distribution of plant resources in these areas is associated with the ways of resource utilization. To explore the characteristics of forest plant flora in northeastern rural areas of Hainan Island, the forest plant resource around 23 villages of Wenchang County and Qionghai County were studied based on the literature collection and plot survey. Results showed that the forest vascular plants in these areas were 967 species, including 39 fern species, 4 gymnosperm species and 924 angiosperm species. The family with less than ten plant species, especially the family with one plant species, accounted for the largest proportion among the family distribution types. The percentage of the family (i.e. with one plant species) in this area was near to that of Jianfengling Mt., while it was 8% higher than that of Wuzhishan Mt. The tropical and subtropical distribution type dominated the geographic elements of family. Among the distribution type of genera, the genera with less than 6 species accounted for the largest proportion, which occupied 45.62 percent of genus of Hainan Province. Moreover, the pantropical distribution type dominated of the geographic elements of genera.
