摘要: 生态系统服务是近年来生态学研究的热点领域,对关键区域生态系统服务的研究具有重要意义。云南省白马雪山国家级自然保护区地处青藏高原南延部分,拥有独特的地理位置,是生物多样性保护的热点区域。本文对该保护区森林生态系统的生物量与生产力、水源涵养、营养物质循环等3项服务的功能量进行了评估。结果表明:保护区森林总生物量2215.86×104 t,生产力171.84×104 t·a-1;水源涵养量11964.56×104 m3;N、P、K年吸收量分别为26025.94 t、2638.57 t、12016.85 t。研究表明,保护区森林生态效益显著,对于维持当地以及周边地区的生态安全具有重要意义。

Abstract: Ecosystem service is currently a hot research topic in ecology, especially for critical regions. Located at the southern edge of Qinghai-Tibet Plateau, the Baimaxueshan National Nature Reserve in Yunnan Province is a biodiversity hotspot with special geographical position. In this study, three typical categories of forest ecosystem services (biomass and productivity, water conservation, and nutrient cycling) in the Reserve were evaluated. The forest total biomass was 2215.86×104 t, productivity was 171.84×104 t·a-1, water-holding capacity was 11964.56×104 m3, and annual absorption of N, P, and K was 26025.94 t, 2638.57 t, and 12016.85 t, respectively, indicating that the forests in Baimaxueshan Nature Reserve had significant ecological benefits, and had importance in maintaining the ecological safety of the local and surrounding areas.
