| 摘 要： | 遥感与GIS集成土壤墒情监测服务系统运行于Windows平台,基于遥感与GIS集成技术,利用热惯量法、植被缺水指数法、植被温度条件指数法和单时相资料回归法等多种模式计算土壤含水量。在遥感监测与墒情分析中考虑背景地理信息的影响,提高了遥感墒情监测的精度和服务水平。该系统具有多种墒情模式计算、图像显示、图像叠加、统计分析、模板处理和输出等功能。应用该系统得出的2005年4月河南省遥感墒情分布图和干旱面积与实测结果基本一致。

| Abstract: | The monitoring and service system of soil moisture is based on the integrated technology of remote sensing and GIS,running on the platform of Windows.The soil moisture is calculated by means of heat inertia,vegetation water-deficiency index,vegetation temperature condition index,and monotonous time-phase data regression methods.Considering the impact of geographical factors in the analysis and remote sensing of soil moisture,the monitoring precision and the service are improved.The system has various functions: modeled soil moisture calculation,image display,statistical analysis,templet processing,etc.The soil moisture distribution and drought area of April 2005 provided by the system are in agreement with the observation basically. |
