    Abstract Zhujiang Water Conservancy Commission of the Ministry of Water Conservancy has monitered dynamically the area of Hekouwan-Lingdingyang of Zhujiang for 13 years with satellite remote sensing data.The satellite image data of 25 temporal of tidal current and water situation from 1973 to 1992 were collected.The dynamic monitoring is mainly for the study of suspended mud and sand content in water at Hekouwan and their distribntion characteristics;the coastline and shoal terrains near the bank and their dynamic change;flowing area characteristics; the projects current situation and change along and near the bank and their affection to water dynamics of river mouth.The satellite remoto sensing images were processed with computer and optical image processing technique,and analyzed according to water dynamics of river mouth and geoscience theory.The analyzed results became the new scientific basis for the planning of Lingding river mouth hamese and project implementation,reasonal usage of resources at shallows,the development and hamess of river courses.Some suggestions have been adopted by operation departments,and brought good social and economical benefits.

    INTERPRETATION OF SATELLITE IMAGE AND PRELIMINARY RESEARCH ON DANBA WHIRL STRUCTURE
    Liu Shangzhong, Zhang Lianying
    REMOTE SENSING FOR LAND & RESOURCES. 1994, 6 (3): 25-33.   DOI: 10.6046/gtzyyg.1994.03.04
    Abstract   HTML   PDF (1912KB) ( 834 )

    Abstract Songpan-Ganzi orogenic zone has long been known as“Bermuda in Geology of China”.Interpretation of TM satellite image in association with information of the landforms,drainage distribution pattern and neotectonism reveals a whirl structure centering around Danba on the eastern side of this orogenic zone.This has been verified by the stratigraphic information,metamorphic trait,fold shape and fracture pattern.The paper makes an approach to its formation and evolutionary process.

    APPLICATION OF REMOTE SENSING TO STUDY OF ENGINEERING GEOLOGICAL ENVIRONMENT ON BAOJI-TIANSHUI RAILWAY
    Zhen Chunxiang
    REMOTE SENSING FOR LAND & RESOURCES. 1994, 6 (3): 34-39,62.   DOI: 10.6046/gtzyyg.1994.03.05
    Abstract   HTML   PDF (480KB) ( 664 )

    Abstract Baoji-Tianshui railway is throat district of the Asia-Europe Continental Bridge. To increase transportation capacity this“railway caecum”must be dre dged. In this paper, remote sensing technology is applied to engineering geological interpretation and investigation of geological calamities, various factors which induce the geological calamities in this area, is analysed. Further, the region engineering geological environment is evaluated synthetically, in order to provide scientific basis for Constuction of the second railway and harnessing the geological Calamities.

    APPLICATION OF REGRESSION ANALYSIS METHOD TO SPECTAM OF ROCK AND CHEMICAL COMPONENT
    Liu Yunliang, Wu Zhishan, Wang Xiaopei, Jia Jianxiu
    REMOTE SENSING FOR LAND & RESOURCES. 1994, 6 (3): 48-54.   DOI: 10.6046/gtzyyg.1994.03.07
    Abstract   HTML   PDF (429KB) ( 781 )

    Abstract This paper applies method of multivariate rogression to study corelation between spectral characteristics of rocks and Chemical Component of rocks.The main chemical components controlling the rocks spectum are found out.The main chemical component of sedimentary rock,metamorphic rock and eruptive rock which effect rock sepectum are also determined.The study discovers that spectra characteristios of H2O+ and H2O- is different to some extent.The results of research show that the new method has good prospects for the evaluation and application of the spectral characteristics of rocks.

    THE APPLICATION OF REMOTE SENSING IMAGE RECOGNITION MODEL OF OIL TRAPS IN THE OIL──GAS PROSPECTING
    Yang Jingen, Yu Jinxin, Wen Xiangquan, Sun Sushen
    REMOTE SENSING FOR LAND & RESOURCES. 1994, 6 (3): 55-62.   DOI: 10.6046/gtzyyg.1994.03.08
    Abstract   HTML   PDF (502KB) ( 733 )

    Abstract According to the theory of oil-gas micro-leakage,the image model of tone anomaly which reflects the main trend of oil-gas-water distribution can be set up on the basis of relative analysis of TM data and the known oil-gas field,optimum selection of bands combination and image processing.The formation of tone anomalies was related with the type of water accompanied by oil-gas traps and the general mineralization,as well as affected and interfered by landforms,surface,drainage condition of ground water,Quatemary sediment and vegetation.The different surface objects under the same oil-gas bearing condition have different tone indication.The same surface objects under different oil-gas bearing condition also have differernt tone indication.So,the tone anomalies on the remote sensing images are surely ambiguous.In order to reduce the ambiguity of unitary tone anomalies,the image model of linear features-circular structures-tone anomalies of oil-gas traps needs to be set up for the purpose of oil-gas prospecting,using the information of linear features and circular structures on remote sensing images.

    REMOTE SENSING FOR LAND & RESOURCES. 1994, 6 (3): 63-70.   DOI: 10.6046/gtzyyg.1994.03.09
    Abstract   HTML   PDF (1311KB) ( 991 )

    Abstract In this paper, with the quantitative analysis of remote sensing information, the image processing and the feature extract were done. Many important geological and structural information were discovered. According to different scale and original, the information of linear and circular structures are seprarately processed, 3-dimension patterns of remote sensing information were established for the regional and the important structure areas. Through a quantitative analysis of regional fault system, the relatively static structure masses were determinod. And through a, quantitative processing of the information of the circular structures and the joints related to the circular structures in the important structure area, some local structures bearing oil/gas were detemined. Finally,with a synthetic analysis and assessment for local structures, promising areas bearing oil/gas were predicted.
