Karst wetland water resource regulation and storage method based on karst underground river system

Abstract

The invention discloses a karst wetland water resource regulation and storage method based on a karst underground river system. The method comprises the following steps: (1) establishing a wetland rainfall and water level online monitoring system in a karst wetland core area, and establishing a water level online monitoring system at an underground river supply area inlet water area, a runoff area karst cave opening, a drainage area surface outlet and a drainage area underground outlet; (2) establishing a regulation and control facility for guiding, blocking, blocking and storing water at the key position of the karst wetland; (3) automatically collecting the rainfall and the water level of different areas of the karst wetland to a data monitoring platform; and (4) enabling the data monitoring platform to perform comparative analysis on the real-time water level data of the wetland and the critical water level of the karst wetland, and according to different signals of comparative analysis results, enabling a manager to perform regulation and control measures according to different signals in combination with the real-time rainfall, the water level value and the like of the karst wetland. The invention aims to solve the problem of how to regulate and store karst wetland water resources, keep the wetland water level in a reasonable state and maintain a wetland healthy ecological system in the prior art.

Description

technical field [0001] The invention relates to the fields of hydrogeology and karst wetland water resources, in particular to a method for regulating and storing karst wetland water resources based on a karst underground river system. Background technique [0002] Due to the special hydrogeological structure and the impact of human activities in the karst area of ​​Southwest my country, the distribution of water resources in this area is uneven and the ecosystem is relatively fragile. This area often suffers from long-term drought due to serious surface water leakage and serious water and soil erosion, resulting in The ecological environment is constantly deteriorating and the phenomenon of rocky desertification is intensifying. Karst wetland is a kind of water resource occurrence state with less distribution in karst area formed under special geological background conditions. It brings together surface water, groundwater, ecosystem and landscape resources, which is equivale...

Problems solved by technology

[0004] Due to its special karst hydrogeological structure, the distribution of water resources in the whole wetland is extremely uneven, and it is greatly affected by seasonal rainfall. Underground karst wetlands often develop karst underground rivers, and the dynamic changes of underground rivers are extremely unstable. , and the amount of underground river water directly affects the amount of wetland water resources. The regulation and storage of karst wetland water resources under the influence of underground rivers lies in how to scientifically and rationally regulate the amount of underground river water. However, it is still in the exploratory stage and there is no specific regulation yet. storage method
