【摘要】 基于中国陆地生态系统价值当量换算法,结合遥感和GIS技术分析了博州1992—2013年的生态服务价值,并分析了生态服务价值变化的驱动因素。结果表明:1)近22年博州生态服务价值呈先减后增趋势,在空间上的分布特征主要表现为东北部价值高、西部价值低,极低值位于市中心区域,极高值主要位于艾比湖湿地和夏尔希里等自然保护区域;2)土地利用/覆被变化直接影响着各土地利用/覆被类型服务价值对总生态服务价值的贡献,气候因素对生态服务价值的影响呈现出显著的空间差异,经济发展、农业的现代化和政府政策的实施在一定程度上可以促进生态服务价值的增长,而牧民生产经营活动则在一定程度上对生态服务价值的发展起到负作用。更多还原

【Abstract】 Based on the value equivalent conversion method of Chinese terrestrial ecosystems,the study analyzes the eco-service of Bozhou from 1992 to 2013 and analyzes the driving factors of its ecoservice change. The results show that:(1) In the past 22 years,the eco-service in Bozhou saw a decreasing trend first and then an increasing one. The spatial distribution is mainly characterized by high value in the northeast,low value in the western,extremely low value in the downtown area and extremely high values mainly located in the protected areas such as the Ebinur Lake Wetlands and the Shirley;(2) Land use/cover change directly affects the contribution of each land use/cover type service value to the total eco-service. The influence of climatic factors on the value shows a significant spatial distribution. To a certain extent,economic development,agriculture modernized and the implementation of policies can promote the value of eco-service,while pastoral production and management activities constrained the value of ecosystem services.更多还原
