摘　　要：水循环观测基地是指对区域大气降水、蒸发蒸腾、河川径流、断面流量、地下水补径排等要素开展系统性连续观测,是水资源调查监测和水资源管理的重要科学依据。中国水循环观测基地经历了3个发展阶段,取得了丰硕成果,但仍存在观测基地空间布局不合理、部分区域代表性丧失、设备老化落后等问题。为适应新时期地表水地下水一体化水资源调查,在长江流域选取江西省赣州市禾丰盆地作为典型小流域,建设水循环观测基地。在此背景下,介绍了禾丰盆地水循环野外科学观测基地建设进展。此外,基于当地地质环境条件构建了禾丰盆地水循环监测网络,并综合使用遥感综合解译、大气降水监测、地表河流监测、地下水动态监测井、地下水环境分层监测井等技术手段进行定量观测,根据野外监测数据对地表水地下水循环转换进行了初步分析。The water cycle observation,as an important scientific basis for water resources investigation and water resources management,refers to the systematic and continuous observation of regional atmospheric precipitation,evaporation and transpiration,river runoff,cross-sectional flow,groundwater replenishment and drainage.Water cycle observation bases in China have witnessed three stages'development and achieved fruitful results,but there are some problems such as unreasonable spatial layout of observation bases,loss of representativeness of some regions due to urbanization,and old and backward equipment.To adapt to the integrated surface and groundwater resources survey,the Hefeng Basin in Ganzhou City of Jiangxi Province was chosen as a typical small watershed to build a water cycle observation base.In the context,this paper introduces the construction of Field Scientific Observation Base for water cycle of Hefeng Basin.In addition,based on the hydrogeology condition,a water cycle monitoring network was established in the Hefeng Basin.The remote sensing interpretation,atmospheric precipitation monitoring,surface water monitoring,groundwater dynamic monitoring,groundwater multilevel monitoring and other technical means were used for quantitative observation.Based on the field monitoring data,the groundwater-surface water transformation was preliminarily analyzed.
