摘要
按照景观生态学的理论和方法 ,从森林景观格局、景观多样性、景观功能等方面分析了社区人为干扰活动对保护区森林植被的影响。表明长期以来强烈的人为干扰活动导致保护区森林景观多样性和异质性降低 ,并延缓了森林植被恢复演替的进程 ,景观生物量积累少 ,抗干扰能力弱 ,生态功能较差 ,尚难以满足作为我国第 3大河流珠江的源头地区水土保持和水源涵养的需要 。
Adopting the theories and methods of landscape ecology, the influences of human disturbance on forest vegetation of Zhujiangyuan Nature Reserve were analyzed from the following three start points: pattern, diversity and functions of forest landscape. The results of analysis implied that intense human disturbance of long time resulted in the decrease of diversity and heterogeneity of forest landscape, the prolonging of recovery succession of forest vegetation, less accumulation of biomass, fragile to disturbance. The limited ecological function of Zhujiangyuan Nature Reserve could not satisfy the soil and water conservation, the requirement of landscaping construction was urgent.
