摘　　要：水资源缺乏已经成为限制北京市城乡发展的主要因素。进行农用地空间布局与水文过程的关系探讨，可以为编制科学合理的农用地规划提供依据。以北京市怀柔区吉寺流域为例，针对吉寺流域的实际情况选取覆被类型、地形因素和土地管理方式3个影响水文过程的主要因素，探讨其对径流、入渗和蒸发等水文过程的影响；并在此基础上建立基于水文过程的农用地空间布局评价体系，对流域内现状农用地空间布局进行评价，提出农用地空间布局的优化方案。Water shortage has become one of the main reasons constraining the city development of Beijing. Researches on the relations between spatial layout of agricultural land and hydrological processes can provide reference for a scientific and reasonable agricultural land planning. The paper takes the Jisi watershed as an example and selects three major factors affecting hydrological processes： the type of cover, topography and land management. According to current agricultural land layout evaluation, the paper discusses their influences on runoff, infiltration and evaporation, and establishes the spatial layout of agricultural land evaluation system on hydrological process.
