摘　　要：在农业不断发展的今天,如何快速地了解土壤墒情,适时合理地给予农作物生长所需的水分,降低干旱风险,成为了人们关注的问题。而ArcGis强大的空间分析能力,可结合相关数据,将一张普通地图经过前期矢量化处理,自动生成土壤墒情等值线图,指导农业用水。以东营市2023年春季土壤墒情数据为基础,详细介绍了如何利用ArcGis自动生成东营市墒情等值线图,分析东营市内各个地区的土壤墒情状况,为相关职能部门提供旱情数据支撑,有效降低干旱风险。Nowadays,with the continuous development of agriculture,how to quickly understand the soil moisture content,timely and reasonably give the water needed for crop growth,and reduce the risk of drought has become a problem of concern.With the strong spatial analysis ability of ArcGis,a common map can be vectorized in the early stage to automatically generate soil moisture contour map to guide agricultural water use in combination with relevant data.Based on the 2023 spring soil moisture data of Dongying City,this paper introduced in detail how to use ArcGis to automatically generate soil moisture contour map of Dongying City,analyzed the soil moisture status of each region in Dongying City,provided drought data support for relevant functional departments,and effectively reduce the risk of drought.
