Mountainous region slump geological disaster high position property recognizing method based on landscape unit

Abstract

The invention discloses a mountainous region slump geological disaster high position property recognizing method based on the landscape unit. The method comprises the following steps that S1 a mountainous region is divided into different areas based on landscape unit; S2 landscape parameters are extracted, and independent evaluation layers are formed; S3 geological disaster points meeting the requirements serve as high position geological disaster points; S4 the region guiding layer where a high position geological disaster is prone to occur is distinguished and serves as an important checkingregion; S5 a high position geological disaster important region is obtained; and S6 the high position property of the geological disaster is recognized in batches. The method solves the problems thatthe practicality is low because potential danger checking is hard to realize, the threatens of the high position geological disaster are increased because the potential danger checking cannot be conducted timely, and the precision is low because speculation and recognition cannot be conducted according to effective evidences and data existing in the prior art.

Description

technical field [0001] The invention belongs to the technical field of geological disaster identification, and in particular relates to a method for identifying high-level properties of landslide geological disasters in mountainous areas based on geomorphic units. Background technique [0002] As the scope of human activities continues to expand, geological disasters are increasingly threatening human society, bringing huge losses in life, economy, environment, and culture. Many counties and cities across the country have been affected by land disasters to varying degrees, causing great damage to personnel safety and property, of which more than 53% are caused by landslides, and most of them are caused by human factors. In order to actively and effectively prevent and reduce disasters and reduce casualties and property losses caused by regional geological disasters, it is necessary to comprehensively and systematically understand the characteristics of the regional geologica...

Problems solved by technology

[0008] Aiming at the above-mentioned deficiencies in the prior art, the present invention provides a highly practical, timely and accurate method for identifying the high-level properties of landslide geological disasters in mountainous areas based on geomorphic units, which enables timely and accurate identification of high-level geological disasters. Troubleshooting, which solves the low practicality caused by the difficulty of hidden danger screening in the existing technology, the increased threat of high-level geological disasters caused by the inability to timely carry out hidden danger screening, and the low accuracy caused by the inability to speculate and identify based on valid evidence and data The problem
