Аннотация: Стабильность качества подземных вод - важный показатель для оценки качества подземных вод. В низовьях реки Хэйхэ в Китае экологическая среда является плохой, это засушливая и полузасушливая территория на материке. Местные грунтовые воды являются основным источником воды для дома. Для обеспечения стабильности качества подземных вод путем расчета индекса устойчивости подземных вод делается вывод, что стабильность качества подземных вод в этой области очень низкая. Подземные воды слабощелочные. В этом документе для корреляционного анализа Пирсона будут использоваться уровень грунтовых вод в скважине за 2012 год, содержание воды в почве, гидравлическая проводимость и другие показатели, а также результаты стабильности качества подземных вод, результаты показывают, что стабильность качества подземных вод и корреляция уровня грунтовых вод в скважине GW13 сильная, индикаторы почвы и грунтовые воды. качество корреляции плохое.
Annotation: The stability of groundwater quality is an important index to evaluate the quality of groundwater. In the lower reaches of the Heihe River in China, the ecological environment is poor, which is an arid and semi-arid area on the mainland. Local groundwater is the main source of domestic water for people. to ensure the stability of groundwater quality, through the calculation of groundwater stability index, it is concluded that the stability of groundwater quality in this area is very poor. The groundwater is weakly alkaline. This paper will use the 2012 groundwater borehole water level, soil water content, hydraulic conductivity and other indicators and groundwater quality stability results for Pearson correlation analysis, the results show that groundwater quality stability and GW13 borehole groundwater level
correlation is strong, soil indicators and groundwater quality correlation is poor.

Data source
Using the results of 49 groundwater quality tests in Heihe River Basin in 2012 as research samples,[1] the correlation between the physical properties of soil profile and the depth of groundwater level was analyzed. The main imaging factors of groundwater quality in the lower reaches of Heihe River Basin are discussed. Table 1 conventional ion content (mg/l) of groundwater in the lower reaches of

The basic condition of electrolytic solution is electrically neutral, that is, cationic
charge and anionic charge are equal in total, and its mathematical expression is X Zmc= X Zma (Formula 1): Z is the number of ionic charges, mc and ma are the molar concentrations of cations and anions, respectively. The above equation is called the charge balance equation. As a complex electrolytic solution, groundwater also follows the charge balance equation, and its electrical neutrality equation is usually expressed in the form of constant components, that is, (Na+) + (K +) + 2 (Ca2+) + 2 (Mg2+) = (Cl-) + (HCO3-) + (NO3-) + 2 (SO42-) (formula 2) [2] [3] parentheses represent ion molar concentration. Since the chemical components in groundwater include not only constant components but also trace components, the two sides of the above formula can only be approximately equal. In practical application, the charge balance equation is usually used to check the accuracy of the main ion analysis results, that is, E% = (X Zmc, X Zma/ X Zmc+ X Zma) * 100% (formula 3), where E is the charge balance error (%). In general, an absolute value of E less than 5% is allowed, and if the error exceeds 5%, the sampling and analysis process needs to be checked. In this study, the old hot spring data of Eryuan were selected to analyze the ions, including all the constant ions in the charge balance equation, and the results showed that the absolute value of the charge balance error E of all samples was less than 5%. The errors caused by artificial sampling and sample detection are excluded [4] [5].

In this paper, Langlier saturation index and Reizner stability index are used to predict the stability of calcium carbonate in groundwater solution.
LSI=pH-pHs (Formula 4).
The pH value is the pH value of the measured water sample, and pHs is the pH, when the water sample solution is in equilibrium, which is calculated according to temperature, alkalinity, hardness, and total solubility value. Rizner stability index = 2pHs-pH (Formula 5) [6] Table 3 Stability table of groundwater quality in the lower reaches of Heihe

The results show that according to Langerre index 37#, the groundwater reaches
equilibrium with calcite, and the groundwater in other places is prone to scaling and the stability of water quality is poor. According to the Reizner stability index, it is calculated that the corrosive water quality is easy to be corroded, while the other areas are easy to form fouling, while according to the stability index of Reizner, it is easy to corrode water quality, such as 1#> 2#> 3#> 5#> 6#> 8#> 12#> 13#> 14#> 15#, 16#, 17#, 18#, 19#, 26#, 28#, 30#, 31#, 32#, 37#, 38#, 39#, 40#, 42#> 43#> 45#> 47#> 48#> 49#.

From the correlation results, it can be seen that Langerre index has strong correlation with Reizner stability index and SI- calcite and has correlation with GW13 groundwater level; SI- calcite has correlation with GW13 groundwater level; saturated water content has correlation with saturated hydraulic conductivity (cm/h), withering water content, field water content and GW13 groundwater level. Saturated hydraulic conductivity (cm/h) was correlated with withered water content, field water content and GW1; litter water content was correlated with field water content, and field water content was correlated with GW2, GW9, GW11 and GW13. Conclusion
The groundwater in the lower reaches of Heihe River is mostly alkaline water (Ph > 7) with strong scaling ability. The stability of its water quality is poor. Through Pearson correlation analysis. The groundwater level of boreholes in the lower reaches of Heihe River has a strong correlation, and the groundwater of GW13 borehole is highly sensitive, which is strongly correlated with Langlier index,
Reizner stability index and SI- calcite, and the saturated water content is correlated
with saturated hydraulic conductivity (cm/h), withering water content, field water
content and GW13 groundwater level.
