| 摘 要： | 运用景观生态分类原则和群落生态学原则,建立了肖坑小流域森林景观三级分类系统,并选用景观多样性(SHDI)、均匀度(E)、景观优势度(D)、最小距离(NHI)和连接度等景观指数对三级森林景观格局进行了分析。结果表明,肖坑小流域森林景观以常绿与落叶混交的阔叶林的中幼龄林为主。森林景观的景观多样性指数和优势度指数都较大而均匀度指数较小,表明景观类型丰富,但类型之间的面积差别较大,分布不均匀;最小距离指数和连接度指数都较小,斑块分布接近团聚分布,信息交换有一定的难度,不利于生物多样性保护和生物资源管理,今后经营管理中要加强对森林的保护,尽量减少森林旅游、采茶等人为经营活动对环境的干扰。

| Abstract: | Applying the landscape and community ecological classification principle,a three-level classification system of forest landscape was built at Xiaokeng minor watershed in Laoshan natural reserve area in Anhui Province.The forest landscape pattern was analyzed by calculating the landscape indices such as the diversity,the evenness,the dominance,the nearest neighbor index and the connectivity etc.The results showed that the young and the middle age mixed evergreen and deciduous broad-leaved forest was the domi... |
