Description

Technical Field

[0001] The present invention belongs to the field of geological disaster prevention and control, and particularly relates to a rapid preparation system and method for multi-level warning maps of geological disaster meteorological risk warning. Background Art

[0002] Geological disaster meteorological risk warning is an important means of geological disaster prevention and control, which can effectively reduce casualties. Since 2003, geological disaster meteorological risk warning work has been successively carried out in provinces across the country, and a business system of ministry-province coordination, city-county linkage, and full-region connection has been established. Systems related to geological disaster meteorological risk warning have been developed to release warning dynamics. However, due to different methods adopted by each province and city in geological disaster meteorological risk warning, warning maps have various levels such as province-city, county-district, and township-street, but there is no unified determination method for warning maps at each level, and the warning units only target management units at different levels, without considering the basic units where geological disasters such as landslides and debris flows occur.

[0003] The slope unit is an important type of geomorphic unit, defined as the area enclosed by valley lines and ridge lines. It is the basic unit for the development of geological disasters such as landslides and collapses. The slope unit is an important working basis for geological disaster prevention and control and risk management. A small watershed generally refers to a relatively independent and closed natural catchment area below the second- and third-level tributaries, bounded by the watershed and the downstream river outlet section, with a catchment area of less than 50 km 2 The micro-watershed is the smallest natural catchment unit delimited by precisely dividing the natural watershed boundary and forming a watershed topological relationship. The small watershed unit and the micro-watershed unit are important areas where geological disasters occur. As a type of natural geographical unit, they have a relatively independent hydrological cycle process, not only having a clear geographical boundary but also carrying rich natural resources and ecological environment. Geological disaster meteorological risk warning based on slope units, small watershed units, and micro-watershed units can more truly reflect the basic topographic and geologic conditions and other situations where geological disasters occur, and the divided units are more reasonable compared with management units. However, geological disaster meteorological risk warning map products must carry their administrative management attributes. According to the requirements of the "Specification for Geological Disaster Meteorological Risk Warning" (DZ / T 0449—2023) and combined with the actual management needs, the warning area management mode generally follows the principle of implementing city-level warning area management to township-streets and county-district warning area management to village communities. Therefore, it is necessary to convert slope units and micro-watershed units that truly reflect the occurrence conditions of geological disasters into administrative management units.

[0004] At present, a geological disaster meteorological risk early warning model based on slope units and micro-watershed units has been established, but there is no rapid production method for an early warning product for these two types of units, and there is no rapid mapping and modification method for integrating with management units at all levels such as small watershed units, township and street units, and village and community units based on micro-watershed units, slope units, etc., which affects the judgment of the risk trend of geological disasters and restricts the dynamic supervision of geological disaster meteorological risk early warning. Summary of the Invention

[0005] In order to solve the problems existing in the background technology, on the one hand, the present invention provides a rapid preparation system for a multi-level early warning map of geological disaster meteorological risk, including:

[0010] A human-computer interaction module, configured to acquire the modification information of the early warning by an external user;

[0011] An early warning map modification module, in response to the modification information of the early warning by the user, synchronously modifies the early warning map of the management unit according to the mapping relationship table between each management unit and each early warning unit or the mapping relationship table between management units, and updates the early warning map.

[0012] On the other hand, the present invention provides a rapid preparation method for a multi-level early warning map of geological disaster meteorological risk, including:

[0013] S1: Acquire the spatial vector data of the early warning unit and the spatial vector data of the management unit; wherein, the early warning unit includes a slope unit and a micro-watershed unit, and the management unit includes a small watershed unit, a village and community unit, and a township and street unit;

[0015] S3: Construct a mapping relationship table between each management unit and each early warning unit, as well as a mapping relationship table between management units, based on the spatial vector data of the early warning unit and the spatial vector data of the management unit;

[0017] S5: Used to obtain the modification information of the early warning by external users;

[0019] The present invention has at least the following beneficial effects:

[0020] The present invention proposes a method for quickly fusing and mapping geological disaster meteorological risk early warning multi-level early warning map products, which is divided into two links: one is to combine slope units and micro-watershed early warning units to establish a mapping table between different early warning units and administrative management units at all levels such as small watersheds, towns and streets, and villages and communities. By establishing a set of early warning criteria that meet the actual application requirements, the rapid fusion production of early warning maps for different administrative management units such as towns and streets and villages and communities is realized; the other is to combine the requirements for modifying the early warning map in administrative management. By establishing the logical relationship for modifying the early warning map, the modification of early warning maps at different levels is realized, comprehensively supporting the geological disaster meteorological risk early warning disposal work, and promoting the standardized and process-based management of geological disaster prevention and control.
