摘要：基于气象逐日观测数据,选择极端高温和低温典型发生年份,利用InVEST模型和Spearman相关性分析法分析了极端气温对贵州省生态系统服务的影响.结果表明:极端高温和低温影响下贵州省产水分别呈现下降和增加趋势,水质净化分别呈现增加和下降趋势,土壤保持均呈下降趋势.极端高温影响下产水、土壤保持和水质净化变化的空间格局较为接近,而极端低温影响下3种服务变化的空间格局差异突出.极端气温影响下降水量、蒸发量及降水侵蚀力变化是贵州省生态系统服务变化的重要原因.
This paper selects typical occurrence years of extreme high temperature and low temperature events,and analyzes the influences of extreme temperature events on ecosystem services changes in Guizhou Province based on daily meteorological observation data with the methods of InVEST model.The results show that the decreasing and increasing trends have been presented in water yield under the influence of extreme high temperature and low temperature events respectively;whereas the increasing and decreasing trends have been displayed in nutrient purification under the influence of extreme high temperature and low temperature events respectively.However,there are both a decreasing trend for soil retention under the influence of extreme high temperature and low temperature events.The spatial patterns of water yield,soil retention and nutrient purification changes under the influence of extreme high temperature events are relatively close;whereas the spatial patterns of the three services changes under the influence of extreme low temperature events are prominent.The change characteristics of precipitation,evaporation and rainfall erosion force affected by extreme temperature events are the important reasons for the changes of ecosystem services in Guizhou Province.
