Embodiment Construction

[0069] Exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be understood that the implementations shown and described in the drawings are only exemplary, intended to explain the principle and spirit of the present invention, rather than limit the scope of the present invention.

[0070] Embodiments of the present invention provide a method for comprehensive management of regional water and soil environment, such as figure 1 As shown, the following steps S1-S3 are included:

[0071] S1. Build a groundwater level control system based on the water cycle process underground in the area to be treated.

[0072] The recharge sources of shallow groundwater mainly include precipitation, lateral recharge and leakage recharge of confined groundwater, of which the amount of leakage recharge is generally small. In the embodiment of the present invention, Dongying City is taken as an example. The groundwater...

Abstract

The invention discloses a regional water and soil environment comprehensive treatment method. The method comprises the following steps that an underground water level regulation and control system isconstructed based on a water circulation process under a to-be-treated region, a regional rain flood reduction system is constructed on the surface of the to-be-treated region, and combining the underground water level regulation and control system based on the water circulation process and the regional rain flood reduction system, water and soil environment of the to-be-treated region is subjected to isolation protection and permeation enhancing treatment. According to the method, by constructing a seepage intercepting ditch and laying a drainage underground pipe, the underground water levelis lowered, the region soil salinization trend is blocked, the region water and soil environment is improved, the sustainable development capacity of the to-be-treated region is enhanced, meanwhile, the water resource quantity increased in an underground water level regulation and control process is utilized for replenishing ecological water for the to-be-treated region, and the region ecologicalwater available amount is increased.

Description

technical field [0001] The invention belongs to the technical field of comprehensive management of regional water and soil environment, and in particular relates to the design of a method for comprehensive management of regional water and soil environment. Background technique [0002] At present, coastal cities such as Tianjin and Dongying, traditional irrigation cities such as Yinchuan, and regions with strong evaporation in the northwest are facing the threat of land salinization, causing corrosion of airports and buildings, and high costs for urban greening and road construction. , decline in land productivity, and even desertification. For example, in the construction of urban green space in Dongying City, it is necessary to replace the soil at a depth of 1.5m on the surface and lay alkali drainage pipes at the same time, so as to basically guarantee the quality of green space construction. For arable land, it is necessary to flood and irrigate with salt every once in ...
