Characteristics of groundwater circulation in typical karst trough areas:A case study of Longtan trough valley in Youyang, Chongqing [PDF]

open access: yes
Although the southwest karst valley region of China has an abundance of groundwater resources, little is known about the variations in the karst trough valley’s groundwater types and their cycle features. Using the Chongqing Youyang Longtan trough valley

岩层倾向对喀斯特槽谷区地表/地下产流过程的影响

open access: yesShuitu Baochi Xuebao, 2020
喀斯特槽谷区在降雨过程中极易发生水土流失,这使得该区生态环境被破坏。以喀斯特槽谷区为研究对象,通过室内模拟其典型顺/逆层坡面特征及地下孔裂隙发育程度,利用人工降雨试验研究不同雨强条件下地表地下产流特征,从而揭示喀斯特槽谷区地表地下产流机制。结果表明:(1)喀斯特槽谷区地表地下产流受雨强影响,小雨强(30 mm/h)条件下地下产流量大于地表产流量,中雨强(60 mm/h)条件下地表产流量增大且裸坡条件下地表产流量大于地下产流量,大雨强(90 mm/h)条件下裸坡与顺层坡的地表产流量均大于地下产流量。(2 ...

Study on the rainfall threshold of red strata landslides in Bazhong, Sichuan using Kriging interpolation method [PDF]

open access: yes
The Rainfall thresholds are among the most commonly used criteria for predicting rainfall-induced landslides. However, existing empirical rainfall thresholds mainly focused on regional landslide warnings, lacking consideration for the spatial variability

Hydrogeochemical processes of groundwater system and its mining-motivated effect in mining areas of Western China [PDF]

open access: yes
The exploitation of coal resources will destroy the aquifer structure, disturb the groundwater system and produce a new water cycle model. As the focus of coal supply and production, the western mining area is short of water resources and fragile in ...

岩层倾向对喀斯特槽谷区不同土地利用类型土壤分离能力的影响

open access: yesShuitu Baochi Xuebao
[目的] 探索岩层倾向对喀斯特槽谷区土壤分离能力的影响机制,为喀斯特槽谷区预防和治理水土流失提供参考意见。[方法] 以重庆市青木关岩溶槽谷区顺/逆层坡为研究对象,通过水槽冲刷试验,分析不同土地利用类型在顺/逆层坡的土壤分离能力差异,并探讨土壤理化性质对土壤分离能力的影响。[结果] (1)顺/逆层坡土壤分离能力均与土壤有机质含量、>0.25 mm水稳性团聚体含量和全氮含量呈显著负相关(p<0.05),其中,逆层坡有机质含量、>0.25 mm水稳性团聚体含量和全氮含量大于顺层坡。(2 ...
