Abstract: In the karst process, the dissolution of the carbonate minerals, such as CaCO3 and CaMg(CO3)2, is essential in the presence of water and under a normal atmospheric temperature/pressure environment, involving the consumption of atmospheric CO2 into Ca2+/Mg2+ and the anion bicarbonate. Usually, the hy...
Abstract: A study on the stable carbon isotopic fractionation (δ13C) in the process of CO2 assimilation of microalgae is very significant to investigate the role of microalgae in estimate of potential carbon dioxide (CO2) sink. However, till now it is yet unknown how to measure the fractionation on CO2 assimi...
Abstract: Discrete fracture network (DFN) model is one of the most effective means to study the flow path and groundwater flow in a fractured rock aquifer. Based on statistical distributions of geometrical and hydraulic parameters of fractures, two-dimensional discrete fracture network is realized through usi...
Abstract: Groundwater contamination risk assessment is of great significance in protecting, managing and reasonably utilizing karst groundwater. In this paper, various methods in regards with groundwater contamination risk assessment were comparatively reviewed. As a result, a new groundwater contamination ri...
Abstract: Recent 50 years, both groundwater level data and precipitation data were devided into several time periods in this paper. The time lags of groundwater levels to precipitation were quantitatively analyzed by using the method of cross wavelet analysis; and the relationships between the time lags and g...
Abstract: To reveal the influence of karst cave sediments on the sedimentary environment and the sedimentary process, this study was conducted in the middle range of Shanwang cave, Guizhou, in conjuction with previous studies of the cave development and associated geological information of the area. The sedim...
Abstract: In this paper, the status quo of Quaternary fauna fossils in Shuanghe Cave in the course of the previous expeditions and in Guizhou province was overviewed. Research on Quaternary fauna in the Shuanghe Cave in Suiyang County is still in its infancy, and reasons were discussed. In order to accelerate...
Abstract: For increasing the knowledge of Hongguoshu scenic area, as well as offering popular science for the adventure and speleotherapy in the other karst tourist areas, this paper studies the characteristics of geological heritages of Hongguoshu scenic area, with data derived from field survey and previous...
Abstract: Zhijin Cave as a tourist cave with a poorly closed environment connects with the outside via cave tunnel and many shafts and fractures. Due to the change of atmospheric environment and tourist volume fluctuation in summer and autumn, the CO2 concentration and humidity in the cave are usually higher ...
Abstract: This study is to explore the fact and causes of the spatial and temporal variation of air environment in the Dafeng cave. 10 monitoring points were set up along the horizontal tunnel of Dafeng cave; and CO2 concentration,temperature and relative humidity of each monitoring point had been continuousl...
Abstract: Shuanghe Cave is located in Wenquan town, 12 km west of Suiyang county, Guizhou Province. It is a multi-layer cave system, developed in the dolomite strata in the upper Cambrian Loushanguan group. The landscape of the area comprises peak-cluster depression, peak-cluster valley and peak-cluster canyo...
Abstract: The objective of this work is to understand the impact of the Weihe pyrite smelting on the surrounding environment and migration of soil heavy metals due to different land uses and soil types. In total 12 surface soil samples and 28 deep soil samples on 4 profiles were collected from the cultivated ...
Abstract: Huaxi district is located in the south of Guiyang City in Guizhou Province. It bestrides an area between E106°27′-106°52′and N26°11′-26°34′, with a land area of 958.56 km2 and a population size of 4.9×105. Soils are predominated by yellow and lime soils. The area is characterized by humid subtropi...
Abstract: A rational assessment of the coupling relationship between land use and ecological environment is the premise to ensure that the land resources can be sustainably utilized for the economic development in a region. Chongqing is partially situated in karst area with a vulnerable eco-environment where ...
