CURRENT TASK OF KARST RESEARCH
Ren Meie
1982, 1(1): 3-3.
Abstract PDF(59KB) icon1524 icon460
Abstract:
Various practical problems encounterd in karst terrains, which covqr an area of about one-fifth of the whole territory of China, may be summed up into three main aspects, namely, the prediction of karst ; the evaluation of karst; as well as the techniques for detection and experiment in karst research. Owing to the uneven distribution of karst, and the less understanding of the regularities of karst development, karst, prediction still remains at a lower level, e.g. in groundwater exploration for wa...

SYSTEMATIC THEORETICAL ANALYSIS OF THE DISCHARGE OF NIANGZIGUAN SPRING
Qian Xuebo
1982, 1(1): 10-17.
Abstract PDF(457KB) icon1788 icon591
Abstract:
Niangziguan Spring, a karst fissure spring, is situated in the vicinity of the Niangziguan, Shanxi Province. Its average annual flow is 12.6m3/s, and it has a drainage area of 3,560km2. It is one of the largest springs in China. The mathematical model of this spring may be written as: Where Q is the discharge of the spring ( m3/s ) ; P, precipitation ( mm ) ; W, coefficient of weight; a, error of discharge ( m3/s ) ; and t, time ( year ) . Using the observation data of discharge and ...
THE KARST MORPHOLOGICAL CHARACTERS IN SOUTH CHINA
Yang Lizheng
1982, 1(1): 18-26.
Abstract PDF(540KB) icon1889 icon806
Abstract:
The paper deals with the. basic forms of karst water runoff, their interconvertibility and reciprocal recharge, and the process of karst water movement , on the basis of the analyses of the recession curve of discharge , the groundwater fluctuation trend and the correlation between the chemical composition and the flow in the resurgence of the Houzhai subterranean river, Puding, Guizhou. The major space for water storage in carbonate rocks are karst fissures and karst tubes, which constitute a water...
THE KARST MORPHOLOGICAL CHARACTERS IN SOUTH CHINA

1982, 1(1): 27-32.
Abstract PDF(431KB) icon1699 icon576
Abstract:
The karst morphological evolution in South China may be summed up as follows: In the regions where the underground water moves in vertical direction , as in Yunan Plateau , the karst morphology appears mainly to be the sunk morphology.When the region is dominated by the horizontal movement of the underground water , the karst morphology appears to be the rivers and plains, while the limestone plateau is dissected into rock mountains. The foot caves always appear at the foot of the rock mountains. ...
AN OUTLINE OF KARST GEOLOGY IN LUOTA REGION
Yu Haoran, Wu Yingke
1982, 1(1): 33-39.
Abstract PDF(2806KB) icon1659 icon478
Abstract:
Luota,a perfect karst synclinal catchment basin, is situated in a karst mountainous area in the west of Hunan, near Hubei, Sichuan and Guizhou provinces. Carbonate rocks of Permian-Lower Triassic, 881.4-1159.5 meters thick,are distributed in the basin, which can be divided into three karstic suites and six karstic horizons.The fault structures are mainly of two sets trending NE and NW, which control the development of the caves. It is suggested that in addition to the corrcding action of water that ...
SOME KARST CAVE MINERALS IN GUILIN
Wang Xunyi
1982, 1(1): 40-48.
Abstract PDF(2651KB) icon1624 icon518
Abstract:
Karst cave minerals are products of hypergene chemical deposition under the action of groundwater. Some secondary cave minerals have been found in Guilin areaGncluding the Xingan-Guilin-Yangsuo terrain),such as calcite, aragonite, gypsum, hydroxyapatite, variscite, taranakite, woodhoseite and half-opal. The determination results of all these minerals obtained by using polarizing microscope, chemical analysis, X-ray powder diffraction, DTA and scanning electronic microscope are listed and the geneses of the ...
ON THE EFFECT OF PLANT ACTIVITIES UPON THE TROPICAL KARST DEVELOPMENT CASE HISTORY OF THE LONGANG NATURE CONSERVATION REGION
Deng Zigiang
1982, 1(1): 49-57.
Abstract PDF(1763KB) icon1577 icon498
Abstract:
The Longang Nature Conservation Region is situated along the borders of Longzhou and Ningming counties, south Guangxi. It is at present a well protected tropical karst region with seasonal-rain forest. Geologically this region is characterized by carbonate rocks of Upper Devonian to Lower Permian. The karst feature is typified by deeply cut tropical peak-cluster depressions. Karst water drains to Zuojiang and Mingjiang rivers in the form of subterranean runoff. Tropical-rain forest is developed, cov...
CAVE PEARLS
Weng Jintao, Ru Jinwen
1982, 1(1): 58-65.
Abstract PDF(2654KB) icon1531 icon584
Abstract:
Large amounts of cave pearls are well preserved in many limestone caverns in Guangxi. Through detailed studies of these cave pearls, which were found in more than ten caverns in Guilin, Yangsuo, Lingchuan and Nanning , the authors have gone further into the genetic conditions of the pearls. The nucleation of the cave pearls took place mainly in the saturated solution of calcium carbonate with suspended fine dispersive impurities. Layers of lime mud is characterized by mechanical sedimentatio...
THE STATISTICAL METHOD OF SELECTING THE OPTIMUM REMOTE SENSING INTERVALS AND ITS APPLICATION IN CARBONATE ROCK DISCRIMINATION
Shu Shourong, Chen Jian
1982, 1(1): 66-76.
Abstract PDF(672KB) icon1564 icon478
Abstract:
Selecting the optimum remote sensing spectral intervals is an important problem in the study of remote sensing spectroscopy and multispectral remote sensing technique.A relatively strict statistical method of selecting optimum remote sensing spectral intervals is described in the paper , and the details of its principle, computation procedures and application have been given as well. Major carbonate rocks from Guilin Region have been taken to exemplify the concrete effectiveness of the method. The optimum r...
