摘要：作为生态系统服务重要类型,淡水生态系统服务供给能力深受土地利用变化的影响,进而强烈影响着区域生态功能水平及社会经济可持续发展。基于贵州省土地利用、地形、土壤、植被、气候等数据,利用InVEST和ArcGIS软件分析了1995-2015年贵州省土地利用变化对淡水生态系统服务的影响。结果表明:在土地利用变化影响下,1995-2005和2005-2015年间产水和水土保持服务呈增加趋势,而水质净化服务呈下降趋势。三种淡水生态系统服务变化的空间格局存在明显的异质性。1995-2005和2005-2015年间产水与水土保持之间均为协同关系,而水质净化与产水、水土保持之间均为权衡关系。耕地、林地和草地变化对1995-2005年贵州省淡水生态系统服务影响较为突出,而建设用地增加对2005-2015年的影响较大。土地利用变化对水质净化服务的影响强度高于对产水和水土保持服务的影响。
As an important type of ecosystem services, the supply capacity of freshwater ecosystem services is significantly affected by land use change, which strongly affects the regional ecological function and the sustainable development of social economy. Based on the data of land use, topography, soil, vegetation and climate, the effects of land use change on freshwater ecosystem services in Guizhou Province from 1995 to 2015 were analyzed by the InVEST model and ArcGIS software. The results showed that under the influence of land use change, water yield and soil retention increased during 1995-2005 and 2005-2015, while water quality purification decreased. There were obvious heterogeneities in the spatial pattern of three freshwater ecosystems services changes. There was a synergistic relationship between water yield and soil retention from 1995 to 2005 and from 2005 to 2015, while there was a tradeoff relationship between water quality purification and water yield and between water qualitypurification and soil retention. Changes of cultivated land, woodland and grassland had significant impacts on freshwater ecosystem services from 1995 to 2005, while construction land change had a significant effect on freshwater ecosystem services from 2005 to 2015. The effects of land use change on water quality purification were stronger than that on water yield and soil retention.
