太湖流域水资源保护天地一体化监测体系构想

摘要

According to current status and existing problems of monitoring for water resources protection in the Taihu lake valley, the essay provides an idea of an integrated sky-earth monitoring system for water resources protection in the Taihu lake valley based on the application of remote sensing at water environment monitoring. The system consists of network guarantee system, standard system, satellite-earth monitoring system, analysis and evaluation system, and early-warning system. The satellite-earth monitoring system offers monitoring measures of satellite remote-sensing imagery monitoring, automatic water quantity and quality station monitoring, conventional tour gauging and additional mobile gauging. Through a comparison between tour gauging data, automatic monitoring station data and analytic data from satellite remote-sensing images, water environment status distribution of the valley can be analogized. By using standard system to ensure data consistency, network guarantee system to ensure data integration, analysis and evaluation system to describe data utility, and early-warning system to predict and prevent future events based on monitoring data, an overall integrated monitoring is realized.%　　针对太湖流域原有水资源保护监测的现状和存在问题，结合遥感技术在水环境监测中的应用，提出太湖流域水资源保护天地一体化监测体系的构想。一体化监测体系包括网络保障、标准、星地监测、分析评价和预警等系统，其中星地监测体系包括遥感卫片监测、水量水质自动站监测、常规巡测和移动加测，这4种监测手段各有优缺点，具体监测时以常规巡测和自动站监测数据为基础，通过与遥感卫片解析数据进行比对，建立相关关系，类推出全流域水环境现状分布情况；标准体系建设保障监测数据的一致性；网络保障体系建设保障数据的完整性；分析评价系统是对监测数据的实用性表达；预测预警系统基于以往的监测数据，对未来进行预测，这样可实现全方位的一体化监测。
