摘　　要：[目的]掌握横断山区产水量及水源分布空间。[方法]利用In VEST模型评估计算2005—2014年横断山区年均产水量,分析产水量的空间分布特征及其原因。[结果]横断山区年均产水量为1 723.3亿m3,与自然径流量较为接近;产水量的空间分布总体呈现出自西北向东南递增的趋势;年均产水量及其空间分布特征与研究区土地利用/覆被类型、土壤深度、地势等因素存在密切关系。[结论]该研究可为横断山区水文过程进一步研究提供基础资料,同时为区域水资源管理提供科学依据。[ Objective ] To master water production and water distribution in Hengduan Mountains. [ Method ] Using INVEST model, the average annual water yield of Hengduan Mountains between 2005 - 2014 was evaluated and analyzed, and the spatial distribution characteristics of water production and their causes were analyzed. [ Result] The results showed that the annual average water yield was 172.33 billion m3 , which was relatively close to natural runoff. The spatial distribution of water yield showed a trend of increase from northwest to southeast in general. The annual average water yield and its spatial distribution was closely related to land use/cover type, soil depth, topography and so on. [ Conclusion ] The study can provide basic data for further study of hydrological processes in Hengduan Mountains, and provide scientific basis for regional water resources management.
