摘要

为探究河套灌区沈乌灌域在深度节水改造前后地下水环境的演变规律

针对地下水埋深、矿化度以及二者关系

通过区域布井、定位长期监测方式

采用经典地统计学理论

分析地下水埋深和矿化度的时空变化规律。结果表明:(1)深度节水改造后

沈乌灌域地下水埋深呈增大趋势

平均地下水埋深由节水改造前1.83 m增大到节水改造后3.36 m

增长率为83.9%。灌域中心和南部埋深偏大

局部产生漏斗

最大埋深至9.37 m

灌域北部埋深变化为0.6 m以下。(2)节水改造工程实施

使地下水矿化度显著增高

由节水改造前的1 296 mg/L增长为节水改造后的2 634 mg/L

增长103.47%。沈乌灌域地下水矿化度在东南、西北地区表现较高

而在中部地区则表现较低

随着节水改造工程的实施

淡水面积逐渐减少

微咸水面积逐渐增大。(3)研究区内地下水埋深和矿化度的变化呈指数关系

地下水矿化度随着地下水埋深的增大而减小

二者的决定系数为0.170 8。从空间上看

地下水埋深较小的地区

对应地下水矿化度大

地下水埋深大的区域对应矿化度小

摸清灌区地下水水位和水质变化规律

为土壤盐渍化防治提供科学依据。

Abstract

In order to explore the evolution law of groundwater environment before and after the deep water-saving reconstruction in ShenWu Irrigation District

aiming at the groundwater depth

salinity and their relationship

the spatial and temporal changes of groundwater depth and salinity were analyzed by using the method of regional well distribution

positioning and long-term monitoring

and the classical geostatistics theory. The results showed that: (1) After the deep water-saving reconstruction

the groundwater depth in Shen-Wu-irrigated area showed an increasing trend

and the average groundwater depth increased from 1.83 m before the water-saving reconstruction to 3.36 m after the water-saving reconstruction

with an increase rate of 83.9%. The buried depth in the center and south of the irrigation area is larger

and a funnel is generated locally. The maximum buried depth increases to 9.37 m

while the buried depth in the north of the irrigation area changes below 0.6 m. (2) The implementation of the water-saving reconstruction project significantly increased the salinity of groundwater

from 1 296 mg/L before the water-saving reconstruction to 2 634 mg/L after the water-saving reconstruction

an increase of 103.47%. The salinity of groundwater in ShenWu Irrigation District is higher in the southeast and northwest

but lower in the central area. With the implementation of the water-saving reconstruction project

the area of fresh water is gradually reduced

while the area of brackish water is gradually increased. (3) There is an exponential relationship between groundwater depth and salinity in the study area. Groundwater salinity decreases with the increase of groundwater depth

and the coefficient of determination of the two is 0.170 8. From the perspective of space

the area with small groundwater depth corresponds to the high salinity of groundwater

and the area with large groundwater depth corresponds to the low salinity of groundwater

so as to find out the change law of groundwater level and water quality in the irrigation area

so as to provide scientific basis for soil salinization prevention and control.
