为了给灌丛资源的保护及开发利用提供科学依据 ,以样方法做调查 ,研究了分布于阜平驼梁山区的主要灌丛类型和垂直分布规律。根据灌丛植被的类型、气候及人类活动干扰程度 ,大致分为 3个亚带 :寒温性落叶阔叶灌丛带 ( 150 0～ 2 0 0 0m) ,温性落叶阔叶灌丛带( 10 0 0～ 150 0m)、暖温性落叶阔叶灌丛带 ( 50 0～ 10 0 0m)。根据生态环境条件和人类活动干扰程度 ,相应提出了灌丛改造和利用的方式
In order to provide a scientific basis for the protection and exploitation of shrub resources, the sampling method was used to investigate the types of shrubs and their vertical distribution in the Tuoliang mountainous area of Fuping. According to the types of shrub vegetation, the degree of climate and the disturbance of human activities, it is divided into three sub-zones: cold-temperate deciduous broad-leaved shrubbery (150 0 ~ 20 000 m), temperate deciduous broad- 150 0m), warm-temperate deciduous broad-leaved shrub belt (50 0 ~ 100m). According to the conditions of ecological environment and the degree of human activities interference, the corresponding way of shrub transformation and utilization
