2. Geotextile for slowing glacial ablation according to claim 1, characterized in that the weft yarn (4) comprises a plurality of elastic filaments (7) and nylon filaments (8), and in that the plurality of elastic filaments (7) and nylon filaments (8) are staggered.
3. Geotextile for slowing glacial ablation according to claim 1, characterized in that the outer surface of the geotextile body (1) is coated with an ultraviolet absorber.
4. A method of laying geotextile that slows glacier ablation comprising the steps of:
s1: transporting, namely transporting the textile material to glaciers by using manpower or sightseeing cable cars;
s2: paving, namely paving from a high altitude to a low altitude, and downwards rolling by utilizing the gravity of the material;
s3: overlapping, namely overlapping adjacent materials together after the whole material is paved, and overlapping the materials by the width;
s4: compacting, namely, because gravity wind frequently occurs on the alpine glaciers so as to avoid damaging the geotextile, and then pressing the geotextile by adopting rocks every 2-3 meters;
s5: maintenance, in the use process, the geotextile needs to be maintained regularly.
5. The method for laying a geotextile capable of slowing glacier ablation according to claim 4, wherein the geotextile obtained after the step S2 is laid is flattened in time in a place with shrinkage.
6. The method of laying a geotextile for mitigating glacier ablation of claim 4, wherein the S4 pressed rock is bonded to the geotextile with tape.
7. The method of claim 6, wherein the rock is wrapped with a bag woven from geotextile.
