摘要：选择贵州省作为喀斯特山区的典型代表,基于生态环境、土地利用、气候等数据,利用地理信息系统技术和Pearson相关分析法,从空间粒度角度分析淡水生态系统服务权衡-协同关系的空间粒度效应。结果表明:研究区水源涵养对空间粒度变化的敏感性较低,而土壤保持和营养物净化对空间粒度变化的敏感性较高;随着空间粒度增大,水源涵养与土壤保持之间以及土壤保持与营养物净化之间由协同关系转向权衡关系,水源涵养与营养物净化之间的权衡强度增加,营养物净化与水源涵养、土壤保持之间权衡-协同关系粒度效应的空间格局接近,但与水源涵养与土壤保持之间的粒度效应空间格局差异较大;气候因子、地形、土地利用类型结构和分布对空间粒度效应的响应差异是影响喀斯特山区淡水生态系统服务及其权衡-协同关系粒度效应的关键因素。
Taking Guizhou province as a typical representative of karst mountainous areas and based on data of ecological environment,land use,climate and so on,spatial grain size effect of trade-off-synergy relationship between freshwater ecosystem services from the perspective of spatial grain size was analyzed by using methods of geographic information system technology and Pearson correlation analysis.The results show that sensitivity of water conservation in the research area to spatial grain size change is lower,while sensitivity of soil maintenance and nutrient purification to spatial grain size change is higher.With the increase of spatial grain size,synergy relationship between water conservation and soil maintenance as well as between soil maintenance and nutrient purification changes to trade-off relationship,and trade-off intensity between water conservation and nutrient purification increases.The spatial pattern of grain size effect between nutrient purification and water conservation as well as between nutrient purification and soil maintenance is similar,which is different from that between water conservation and soil maintenance.Response differences of climate factors,terrain,land use type structure,and distribution to spatial grain size effect are key factors influencing grain size effect of freshwater ecosystem services and their trade-off-synergy relationship in karst mountainous areas.
