摘要 基于土地利用数据,分析了2010—2015年洱海流域土地利用演变特征、生态系统服务价值变化特征以及人类活动对生态系统格局及服务价值变化的影响。结果表明:(1)洱海流域土地利用类型主要由生态用地向非生态用地转移,其中城镇扩张明显,而生态用地面积有所减少。(2)洱海流域主要生态系统服务类型为调节服务,生态系统服务总价值由2010年的656.03亿元增加至2015年的709.40亿元,增长率为8.14%。(3)洱海流域生态系统格局及服务价值变化主要驱动因素为生态建设工程、城镇扩张和农业开发等人类活动,其中对生态系统及其价值变化的正向影响(54.01%)大于负面影响(45.99%)。 Based on land use data,this paper analyzed the change characteristics of ecosystem pattern,the change of ecosystem service value and the influence of human activities on Erhai Lake Basin from 2010 to 2015.The result showed that:(1)The ecosystem types of Erhai Lake Basin were mainly transferred from ecological land to non-ecological land,in which the urban expansion was obvious,while the area of ecological land was reduced.(2)The main ecosystem service type of Erhai Lake Basin was regulation service.The total value of Erhai Lake Basin increased from 65.603 billion Yuan in 2010 to 70.940 billion Yuan in 2015,with an increase rate of 8.14%.(3)The main driving factors of ecosystem pattern and ecosystem service value change in Erhai Lake Basin were human activities such as ecological construction engineering,urban expansion and agricultural development.The positive impact(54.01%)of human activities on ecosystem and its ecosystem value change was greater than the negative impact(45.99%).
