A method of glacial ablation is detected based on tracer technique

摘要

The invention discloses a kind of methods based on tracer technique detection glacial ablation, this method includes the next steps: 1, the different tracers for adding isoconcentration respectively into several pieces water and make its be uniformly mixed, the volume and quality of each glacier model are recorded simultaneously, if if successively dry glacier model is established in layering frost from inside to outside by several solid carbon dioxides added with tracer; 2, the environmental factor around the model of glacier is adjusted, collects the water sample that glacier model melts under varying environment conditions, and measure the concentration of the various tracers in the water sample; 3, water sample quality, melting rate and the thawing position of the thawing of the different ice sheets of glacier model at different conditions are obtained according to the content of tracer, and according to thawing speed, thawing quality and melt the physical process for deriving practical glacial ablation in position. The application is realized by establishing glacier modeling glacial ablation process, derives the purpose of the ablation speed in practical glacier, further in order to sea level rise and glacier natural calamity carries out early warning analysis.
