区域土地灌溉环境评价与决策分析

国土资源是人们赖以生存和发展的物质基础，土地灌溉环境作为国土资源调查的重要内容，其关键基础设施机井的空间配置对于农业生产具有重要的现实意义。本文以北京市通州区永乐店镇为研究区，基于国土资源调查的多源空间数据，提出了一种对现有土地灌溉环境进行定量评价和优化决策的方法。结果表明，研究区既有机井配置有待进一步改进，优化方案给出的183口新增机井合理分配在优化单元内，能够满足当地农民的土地灌溉需求，同时为土地灌溉环境中机井的更新配置提供了依据。

Evaluation and decision analysis of regional land irrigation environment

Land resources are the material basis for people's survival and development. Land irrigation environment is an important content of land resources surveys, and the spatial configuration of key infrastructure motorized wells has important practical significance for agricultural production. This paper takes Yongledian, Tongzhou, Beijing as the research area, and based on the multi-source spatial data of the land and resources survey, proposes a method for quantitative evaluation and optimization decision-making of the existing land irrigation environment. The results show that the configuration of existing organic wells in the study area needs further improvement. The 183 updated motorized wells given by the optimization plan are reasonably allocated in the set units, which can meet the land irrigation needs of local farmers and provide for the updated configuration of motorized wells in the land irrigation environment.
