太岳山地生态系统服务功能权衡协同关系研究

Study on Synergy and Tradeoff Relationship of Ecosystem Services Function in Taiyue Mountain

生态系统服务功能是当代景观生态学研究的热点,生态系统服务之间存在着潜在的权衡和协同关系。该研究以山西省太岳山地区为研究区域,分析2000-2010年太岳山地区生态系统类型的变化,以及水源涵养功能、水土保持功能、维持生物多样性功能变化以及三者之间的权衡与协同关系,得出近10年来研究区在森林覆盖度高,草地、耕地转换为林地的地区,水源涵养,水土保持功能与生物多样性维持功能大部分表现为协同增长,但也有部分地区生态服务功能出现权衡作用,大多为坡度较陡,林地转换为草地、裸地等类型,在靠近道路、农田和建设用地区域生态系统服务功能出现权衡作用或者协同下降作用。因此太岳山地区对于生态系统服务功能内部的权衡和协同关系的研究,对于未来政府或者生态修复工程的决策具有重要的意义,对其他山地地区的研究具有重要的借鉴意义。

Ecosystem service function is a hot topic in contemporary landscape ecology,and there are potential trade-offs and synergies between ecosystem services.This study takes Taiyue Mountain in Shanxi Province as research area,the ecosys- tems changes,as well as water conservation,soil and water conservation,biodiversity function,and trade-offs and synergies between the functions during 2000-2010 were analyzed.It is concluded that most of the areas with high forest coverage,or grassland and farmland conversion to woodland,water conservation,water and soil conservation function and biodiversity maintenance function are mostly synergistic growth.However,there are some trade -offs in the function of eco-service in some areas.Most of them are of a steeper slope,and the forest land is converted into grassland,bare land and so on.The types of land cover have a trade-off or a synergistic decline in ecosystem services in areas close to roads,farmland and construction areas.Therefore,the study on the tradeoff and synergy of ecosystem service function in Taiyue Mountain area is of great significance to the future government or ecological restoration project decision,and also to the study of other moun tain areas.
