贵州省普白林场森林景观健康评价

摘要

In order to explore the system and methods for forest landscape health evaluation, four indices including forest vigor, organization structure, adaptability, and social value were used to establish a system for the forest health evaluation of Pubai forest farm in Guizhou Province. The results showed that the forest health in Pubai forest farm is unoptimistic, with most of the plantations being in the unhealthy condition. The relative healthy states of different working areas are Central area 〉 Maao area 〉 Dapo area 〉 Xiaohe area 〉 new farm site, and this is mainly attributed to their different systematic organization vigor and resilience. As the tree species and forest structure in this area are simple, enhancing and intensifying of the biodiversity and multi-layers of the forest are the important work for the forest farm in the future.%为了探索森林景观健康评价的体系和方法，采用森林的活力、组织结构、适应性和社会价值四个方面为指标，构建了一套评价森林健康的指标体系和评价方法，对贵州省普白林场的森林健康进行了评价，结果表明普自林场人工林的健康状况不容乐观，多数处于不健康状态以下。针对各工区的相对健康状况，得出其健康性为：中心工区〉麻凹工区〉大坡工区〉小河工区〉新场部，这主要是体现在系统的组织活性和弹性上，即该林场的树种单一，生态系统结构简单，因此加强对林场生物多样性的保护以及复层林分的形成是林场的当务之急。
