基于GIS的土壤墒情遥感监测系统设计

Design of Remote Sensing Monitoring System for Soil Moisture Content Based on GIS

针对传统土壤墒情监测系统存在监测值和实际值偏差较大的问题,提出一种基于地理信息系统(Geographic Information System,GIS)的土壤墒情遥感监测系统。首先,建立土壤墒情模型,采集并处理土壤墒情遥感影像,提取遥感监测影像信息结果;其次,利用GIS数据模型设计监测数据库,存储并管理遥感监测信息;最后,进行对比分析。实验结果表明,利用该系统获得的土壤含水率监测值与土壤含水率实际值接近,结果偏差小,可实现长期可持续监测目标。

A remote sensing monitoring system for soil moisture based on Geographic Information System(GIS)is proposed to address the issue of significant deviation between monitoring values and actual values in traditional soil moisture monitoring systems.Firstly,establish a soil moisture model,collect and process remote sensing images of soil moisture,and extract information from remote sensing monitoring images.Secondly,use GIS data models to design monitoring databases,store and manage remote sensing monitoring information.Finally,conduct a comparative analysis.The experimental results show that the monitoring values of soil moisture content obtained using this system are close to the actual values of soil moisture content,with small deviation,and can achieve long-term sustainable monitoring goals.
