| 摘 要： | 通过对干扰行为和生态系统的生态过程分析,认为自然干扰属于自然演替的正常范畴,不作为生态完整性评价的影响因子,证实人为干扰在生态系统完整性评价中占有重要地位。文章分析了人为干扰对森林生态系统在结构和功能上的影响,通过对指标的筛选得到人为干扰压力模型,并采用层次分析法(AHP)计算出各指标权重。最后提出对森林生态系统完整性评价的新思路。

| Abstract: | By analysis of the disturbance behavior and ecological process of ecosystem,it was confirmed that human-caused disturbance played an important role in assessment of ecosystem integrity.And it was considered that natural disturbance could not be taken as impact factor for assessment of ecosystem integrity but belonged to the normal scope of natural succession.In this paper,the impacts of human-caused disturbance on structure and function of forest ecosystem were analyzed.A human-caused disturbance pressure model was formed through screening indicators,and the indicators weights were figured out using analytic hierarchy process（AHP）.Finally a new idea on assessment of ecosystem integrity was put forward. |
