旱灾遥感预警监测评估技术——以2011年长江中下游旱灾为例
Assessment Technology of Remote Sensing Drought Monitoring——A Case Study on the Drought in the Lower Yangtze Region
摘要
Abstract
From March to June 2011, a major drought occurred in the middle and lower reaches of Changjiang River, it lasted a long time and affected a wide coverage, had a great impact on people's production and life. Aimed at this disaster process, through typical cases studies, this paper summarizes the process of using cloud parameters algorithm, spectral-dimension and temperature drought index, change detection of water area and population statistical method of industrial output loss respectively to early-warn, monitor and assess meteorological drought, agricultural drought, hydrological drought and socio-economic drought. It is the important future development and application direction of dealing with drought to integrate the observation results of different angles to comprehensively judge the disaster condition. In the end, this paper discusses the lack of current drought product system and disaster fighting process, and indicates the necessity of establishment of disaster early-warning, monitoring and assessment system based on spatial information technology.关键词
