“…Understanding soil freezing and thawing is vital in understanding winter evapotranspiration [1], runoff [2], groundwater recharge periodically [3], soil formation [4], predicting the movement of nutrients/contaminants as they seep through frozen layers of soil [5], and landscape evolution [6] in cold regions. The soil pores were expanded by soil frost heaving during the freezing period [7][8][9]. Whereas, the soil pore collapsed along with the ice-water phase change during thawing [4,10,11].…”

The soil freezing characteristic curve (SFCC) describes the relationship between the freezing point and unfrozen water content, which are two critical parameters in depicting the heat, solute, and water transport in frozen soil. In this paper, we propose a novel Generalized Clapeyron Equation (GCE)-based model, the GCE-Salt Model, to better capture the SFCC in frozen soil in the presence of solute. It keeps the matric potential Ψf in the GCE as its original meaning and incorporates the effect of solute potential in the equilibrium freezing temperature. The performance of our GCE-Salt Model was validated by both lab and field experimental data and compared with related models (Combined Model and GCE-Tan Model). The GCE-Salt Model performed exceptionally well in extremely saline soil and it performed well in both non-saline and saline soil. (1) Our GCE-Salt Model could capture the SFCC of non-saline soil equally as well as the Combined Model (NSE = 0.866); (2) our GCE-Salt Model performed similarly well as the Combined Model and a little better than the GCE-Tan Model for the slightly to highly saline soil (NSE ≥ 0.80 for three models); and (3) our GCE-Salt Model (NSE = 0.919) beat the Combined Model (NSE = 0.863) and the GCE-Tan Model (NSE = 0.62) in capturing the SFCC of extremely saline soil, mainly because the inherent expression of our GCE-Salt Model can more accurately capture the freezing point. Our findings highlight the effect of solute potential on the ice–water change and could improve the understanding of the effect of freezing and thawing on the thermal–hydrological processes, structure of saline soil, and landscape evolution in cold regions.

“…For the time being, scholars' studies on influencing elements of water resources safety at home and abroad mainly focus on three aspects: water resources, social economy and ecological conditions (Liu et al, 2017). Research methodologies now available principally draw on research strategies of water resources sustainability, covering PSR (Pressure-State-Response) model (Li et al, 2023), WRF (water resources footprint) (Hou et al, 2020), MES (method of expert system) (Sun et al, 2018), AHP (analytic hierarchy process) (Ding et al, 2024), SPA (set pair analysis model) (Peng & Qin, 2019), DMBP (diminishing marginal benefit principle) (Shi et al, 2010), FIAM (fuzzy integrated assessment method) (Li et al, 2017), and so on. A few scholars have also applied these methods and models to the evaluation of water resources safety in southwestern karst areas, China.…”

Quantitative evaluations on water resources safety in karst areas are of great significance for enacting logical water resources development policies, promoting the sustainability of water resources and realizing sustainable socioeconomic progress. Therefore, according to special characteristics of hydrology and water resources in karst regions of southwestern China, this study constructed an evaluation indicator frame of water resources safety from five aspects: Water resources occurring (WRO), Water environment condition (WEC), “Engineering” water scarcity (EWS), Water resources utilization (WRU) and Water resources management (WRM). Combined weights of assessment indexes were calculated by analytic hierarchy process (AHP) and entropy-right method, and an assessment model of water resources safety in karst regions was constructed based on the coupling of analytical comparison method and alterable vague sets. Taking Guiyang as an example, the water resources safety situation of Guiyang from 2013 to 2022 was assessed with this model and its main obstacle factors were analyzed. Results indicate that the level of water resources safety in Guiyang is on the rise, and the safety level rises from unsafe level to relatively safe level. Water resources utilization is the primary element affecting water resources safety of Guiyang. Total water resources volume, water yielding modulus, consumptive use of water per 10,000 Yuan GDP and exploitation and utilization rate of water resources are primary obstacle factors to the improvement of water resources safety level. The improvement of water resources provision, water resources using efficiency and water resources management all show that human behaviour has a significant impact on water resources safety. The assessment model can impersonally reflect temporal evolution features and main constraints of water resources safety in karst regions, and evaluation results are close to the actual situation, which can provide an effective, feasible and intuitive method for water resources safety evaluation in karst areas.
