Description

Technical Field

[0001] This invention relates to the field of water resource management and assessment technology, and more specifically, to a groundwater resource assessment method based on ecological factors. Background Technology

[0002] With the intensification of global climate change and the increasing scarcity of water resources, groundwater, as a vital water resource, faces increasingly severe challenges in its development and protection. The rational utilization of groundwater resources is not only related to regional water security but also directly affects the sustainability of the ecological environment. Especially in areas with significant ecological characteristics (such as arid, semi-humid, and humid regions), the assessment and management of groundwater resources face complex challenges.

[0003] Currently, groundwater resource assessment methods typically rely on traditional hydrological and meteorological data and geological exploration data, estimating groundwater reserves and exploitation potential by measuring indicators such as groundwater level, flow rate, and water quality. These traditional methods are widely used in many regions, but in areas with significant ecological characteristics, groundwater resource assessment and management have some shortcomings, mainly in the following aspects:

[0004] Existing groundwater resource assessment methods often focus on hydrogeological parameters, such as groundwater level, flow, and storage, while neglecting the influence of ecological and environmental factors. Ecological factors, such as vegetation cover, soil permeability, and precipitation, have a significant impact on groundwater recharge, flow, and storage, but existing methods typically do not fully incorporate these factors, leading to inaccurate groundwater resource assessment results, especially in areas with complex ecological environments where assessment results often have significant biases.

[0005] Existing groundwater resource assessment methods largely rely on traditional single data sources (such as groundwater level and flow rate), lacking dynamic monitoring of ecological characteristics across large areas. The accuracy of the assessment results is affected by various factors, including data collection methods, sample distribution, and measurement precision. Especially in large, diverse ecological areas, a single data source cannot fully reflect the state of groundwater, leading to instability and inaccuracy in the assessment conclusions.

[0006] Traditional groundwater assessment methods often fail to adequately consider the long-term sustainability of the ecological environment when calculating groundwater reserves and exploitable quantities. For example, many regions suffer from over-exploitation of groundwater, and the relevant assessment methods have not effectively highlighted the ecological burden and demands on groundwater resources, leading to groundwater extraction exceeding the carrying capacity of the ecosystem and further exacerbating the deterioration of water resources and the ecological environment.

[0007] Currently, most groundwater resource assessment methods rely on surface hydrological and meteorological monitoring networks and manually collected hydrological data. These data collection efforts are costly, time-consuming, and cannot cover a wide range of areas. For regions with significant ecological characteristics, especially arid or remote areas, insufficient hydrological monitoring network coverage and difficulties in data acquisition result in a lack of real-time accuracy and representativeness in groundwater resource assessments.

[0008] Existing groundwater resource assessment methods often focus on simple evaluations of water quantity or quality, lacking comprehensive management measures for the rational development, use, and ecological protection of groundwater resources. Many regions have failed to effectively combine ecological protection needs with groundwater extraction demands, leading to the disorderly development of water resources and impacting the health of the ecological environment and the sustainable use of water resources.

[0009] Therefore, we urgently need to design a groundwater resource assessment method based on ecological factors to solve the problems mentioned above. Summary of the Invention

[0080] The following detailed description is provided in conjunction with specific embodiments;

[0081] Example: Groundwater Resource Assessment and Management Based on Ecological Factors

[0082] This embodiment uses an arid region as an application scenario to demonstrate the complete implementation process of a groundwater resource assessment method based on ecological factors. The method includes steps such as assessment area delineation, data acquisition, model construction, management plan formulation, and real-time monitoring.

[0083] Step 1: Division and characteristic analysis of the evaluation area;

[0084] First, remote sensing technology and geographic information systems (GIS) are used to collect the ecological and environmental characteristics of the target area.

[0085] The target area is an arid region. Assume the following ecological and environmental data: vegetation cover V c =20%; average annual precipitation P a =200mm; Annual average evaporation E a =1200mm; Soil permeability coefficient k t =0.01cm / s;

[0086] The target area was divided into several evaluation areas using GIS technology, and the ecological characteristics of each sub-area were recorded in the database. Weight coefficients were assigned to each factor: w1 = 0.3, w2 = 0.4, w3 = 0.2, w4 = 0.1. The maximum value is:

[0087] Calculate the ecological factor index E i :

[0088]

[0089] E i =0.356;

[0090] That is, the comprehensive ecological factor index E i =0.356.

[0091] Step 2: Collection and Preprocessing of Basic Groundwater Data. For arid areas, basic groundwater data is collected, including groundwater level, flow rate, recharge, and water quality.

[0092] Groundwater level h(x,y,z) = 8m (assuming uniform water level for simplified calculation); natural recharge R = 274m³ 3 / d;

[0093] Data was acquired through hydrological monitoring networks, remote sensing technology, and field surveys. After standardization and removal of outliers, a groundwater resource dataset was established.

[0094] Step 3: Construction of an evaluation model for groundwater resources;

[0095] An evaluation model was established based on the collected data to calculate the groundwater storage (V):

[0096] V=∫ A (μ·h(x,y,z)f(E i ))dA;

[0097] μ = 0.3 (specific yield of sandy aquifers in arid regions); h(x,y,z) = 8m; f(E i ) = E i =0.48 (E is used directly as the ecological factor correction function) i A = 1000m 2 (Assess the area area).

[0098] Since (h(x, y, z)) and f(E) i Since the integer part is constant in this region, the integral can be simplified to:

[0099] V=μ·h(x,y,z)·f(E i )·A;

[0100] V=0.3·8·0.48·1000=1152m 3 ;

[0101] Calculate the total groundwater flow Q 总 Q 总 =α·V, then:

[0102] Assume α = 0.1d -1 (10% of the reserves are released daily, estimated based on the characteristics of aquifers in arid regions), that is:

[0103] Q 总 =α·V=0.1·1152=115.2m 3 / d;

[0104] Step 4: Comparison of groundwater extractable quantity and ecological demand; calculation of groundwater extractable quantity Q. e :

[0105] Q 可开采 =Q 总 -Q 生态需求 ;

[0106] Q 总 =115.2m 3 / d;Q 生态需求 =50m 3 / d (ecological demand in arid areas, estimated based on vegetation cover and soil moisture requirements).

[0107] Calculation yields: Q e =115.2-50=65.2m 3 / d.

[0108] Step 5: Groundwater sustainability assessment and recharge analysis to calculate sustainable extraction volume Q 可持续 :

[0109] Q 可持续 =Q 总 -Q 生态需求 -Q 流失 ;

[0110] Q 流失 =30m 3 / d (loss amount, estimated by hydrological model and adjusted to match arid zone conditions).

[0111] Calculation yields: Q 可持续 =115.2-50-30=35.2m 3 / d;

[0112] Step 6: Develop an optimized management and protection plan for groundwater resources;

[0113] Based on the assessment results, an optimized management plan was developed: the mining volume was adjusted to not exceed 65.2m. 3 / d, to ensure that the exploitable quantity is not exceeded;

[0114] Designate water source protection areas and restrict over-exploitation; construct rainwater harvesting systems and increase the area by 20m. 3 / d manual resupply.

[0115] Step 7: Implementation of Ecological Protection Measures and Delineation of Water Source Protection Zones. Implement ecological protection measures:

[0116] Plant drought-resistant vegetation, V c Increase the coverage to 50%, enhance water supply, dynamically adjust the protected area according to ecological needs, and adopt ecological water conservation technologies to increase water supply.

[0117] Step 8: Real-time monitoring and dynamic updates;

[0118] Dynamic updates are performed through a computer system (including data acquisition, processing, evaluation models, optimization management, and real-time monitoring modules).

[0119] Latest monitoring data: Q 总 Drop to 100m 3 / d, update the mineable quantity, then:

[0120] Q 可开采 =100-50=50m 3 / d;

[0121] Implementation results: Through the above steps, the groundwater resources in the arid area have been scientifically assessed and managed.

[0122] The groundwater storage (V) is 1152 m³. 3 Minable quantity Q 可开采 It is 65.2m 3 / d, Sustainable mining capacity Q 可持续 335.2m 3 / d, which meets ecological needs while achieving sustainable use of water resources.

[0123] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
