Embodiment Construction

[0020] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0021] In view of the lack of understanding of the modern moraine-type provenance of marine glaciers in the prior art, there is no estimation method for this kind of provenance. The invention provides a geometric model, puts forward the concept of the glacier sand content rate, and calculates the source static storage through the glacier geometric model and the sand content rate.

[0022] The application principle of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0023] Such as figure 1 As shown, the marine glaciers modern moraine type provenance determination meth...

Abstract

The invention belongs to the technical field of geological disaster investigation, and discloses a method for measuring the modern moraine type provenance of marine glaciers. The method firstly defines the modern moraine-type provenance of the marine glacier, and the moraine-type provenance is abbreviated to moraine-type provenance. The debris flow provenances in southeastern Tibet are different from those in other regions due to the special topography and climatic factors, which directly affect the debris flow activity in this region with the climate change. The method generalizes the geometric model of the valley glacier forming the source of the material based on the field investigation and the remote sensing interpretation, and estimates the glacier volume by obtaining the geometric parameters of the glacier through the remote sensing. The concept of glacier sand content is put forward. Static provenance reserves can be estimated by glacier volume and glacier sand content. Based onthe investigation and estimation of modern moraine-type provenances of marine glaciers in southeastern Tibet, the present invention provides an estimation method for calculating the static reserves of such provenances.

Description

technical field [0001] The invention belongs to the technical field of geological disaster investigation, and in particular relates to a method for measuring the quantity of modern moraine-type provenance of marine glaciers. Background technique [0002] The southeast of Tibet is one of the most severe glacial debris flow disaster areas in China. This area is located at the junction of the Eurasian plate and the Indian Ocean plate to form the eastern tectonic junction. The terrain is high mountains and canyons, and the Indian Ocean warm and humid air flows along the Yarlung Zangbo River and Palong Zangbo Canyon. Water vapor, water vapor over the ridges to form marine glaciers. With the influence of global climate warming and other factors, the marine glaciers in this area are prone to large-scale advance and retreat. Active marine glaciers have provided a large amount of water and material sources for the development of glacial debris flows in this area. Historically, Guxian...
