Problems solved by technology

[0002] Combined with the development and evolution of contemporary hydrogeology, it was born into environmental hydrogeology and ecological hydrogeology; at present, there is no scientific and accurate basis for the development, utilization and management of groundwater resources, and it is in a disorderly and chaotic mining mode, which has caused great harm to the environment. It is a key hydrogeological problem that must be solved for the rational development and utilization of groundwater resources, and it is an urgent need for ecological environment protection.

Embodiment 1

[0015] Embodiment 1, the evaluation of exploitable groundwater resources in the Nalingele River Basin

[0016] The first step, investigation: using test pits, shallow wells, and cross-section investigation methods to obtain the relationship between the distribution of wetlands in the front part of the alluvial fan of the Nalingele River-fine soil plain and the buried depth of groundwater has the following spatial distribution rules, According to this rule, the current situation of the wetland area and the basis of the distribution of the buried depth of the groundwater are obtained, and it is concluded that the buried depth of the groundwater level is less than 4m, which is the wetland range of the Nalingele River Basin.

[0017] Middle and back edge of alluvial-diluvial fan: the buried depth of the groundwater level is shallow, generally greater than 4m, the salinization of the surface is light, only fennel grows, and it develops sporadically in the form of clusters, and the f...

Abstract

A drought region underground water exploitable resource quantity evaluation method includes the following steps: a first step, performing investigation; a second step, performing remote sensing interpretation; a third step, acquiring the perennial average conversion quantity of surface water into underground water; a fourth step, acquiring relevant parameters; a fifth step, calculating and drawingan underground water resource development utilization curve, and determining the underground water exploitable resource quantity. The beneficial effects of the invention are that the method is a newunderground water resource evaluation thought with the ecology as a constraint condition, can break the conventional evaluation thoughts with a stable underground water level as a constraint conditionin this field, is an innovative product having application and promotion value, and is a new technical method combined with the ecology and the underground water resource evaluation; in the curve inthe method, the corresponding wetland area change condition can be searched according to the demand of different underground water exploitable resource quantities; and underground water resource development utilization management and red line setting can be performed according to the curve.

Description

1. Technical field [0001] The invention relates to the technical field of groundwater evaluation, in particular to a method for evaluating exploitable groundwater resources in arid regions. 2. Background technology [0002] Combined with the development and evolution of contemporary hydrogeology, it was born into environmental hydrogeology and ecological hydrogeology; at present, there is no scientific and accurate basis for the development, utilization and management of groundwater resources, and it is in a disorderly and chaotic mining mode, which has caused great harm to the environment. It is a key hydrogeological problem that must be solved for the rational development and utilization of groundwater resources, and it is an urgent need for ecological environment protection. 3. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the present invention provides a method for evaluating groundwater exploitable resources in arid areas, which is ch...
