The Research On The RS Dynamic Monitoring Mode Of The Yellow River Icicle Hazard And The Ice Regime Information Extraction Model

The flood of Yellow River is always the serious trouble of Chinese, and ice flood disaster have the maximum influencing factors and the most complicated flooded theory, it was concluded with ancient adage "the ice flood burst and official innocence" and " estival flood easily prevented and ice flood hardly defended". So, it is very significative that researching flooded theory of ice flood of Yellow River and studying quickly monitoring model of disaster condition of ice flood and excogitating a set of dynamic RS monitoring pattern of ice flood disaster for national economy and social continuable develop.Central works and researchful content : 1,I roundly studied developed theory and evolutive process and influencing factor and flooded feature of ice flood disaster of Yellow River; 2,Based on background and feature and applications of secondary planet, I excogitated a kind of reasonable dynamic RS monitoring pattern of Yellow River; 3 , I discussed background and method of process and application of MODIS and CBERS-02 data, and I understood arithmetic of MODIS productions, then I studied automatic geometrical register arithmetic and lighteness or temperature arithmetic and cloud detection arithmetic and ice detection arithmetic based on MODIS data; 4,I researched constitutional theory and finished method of automatic ice detection model; 5, I discussed application of CBERS-02 on the ice flood monitoring of Yellow River.Central conclusions :1. The ice flood disaster of Yellow River is very complicated phenomenon, in other words, It has natural and social feature, the influence of this disaster would reduce rock bottom if we combined project measure with non-project measure, the dynamic RS monitoring with GIS is effective one of non-project measure.2. "four secondary planets and three sources" dynamic RS monitoring pattern is the present best combination of data, It was proved that it was effective.3. This model had high delicacy and effectively finished Real-time(quasi-Real-time) dynamic monitoring of ice flood disaster of Yellow River.4. Application of CBERS-02 data on elaborate monitoring of the ice flood of Yellow River is very good, specially side-swing of CBERS-02 could quickly finish dynamic monitoring of unexpected disaster area.Central innovations :1. I first brought forward "four secondary planets and three sources" dynamic RS monitoring pattern based on MODIS,ETM+,CBERS-02, RADARSAT, and actual applications of the model achieved favorable effect.2. I first brought forward extracting model of information of ice flood of Yellow River, It was proved that it was effective.3. I successfully realized dynamic monitoring ice flood of Yellow River using side-swing of CBERS-02 for the first time, it opened up a new field on homemade satellitic application.
