This paper introduces many good conditions of economic development along the Jingjiu railway line, which brought by Hongkong's returning motherland and Jingjiu railway's opening. It expounds the necessity of investigation and evaluation the land and resource as well as its development conditons. At same time, it discusses the possibility and major investigation task of using remote sensing technique.
This paper deals with the function of remote sensing technique in Jingjiu railway construction, such as it was used in geological and hydrological interpretation as well as aerial mapping, ect., at the same time, it gives the rationalization proposal of taking further steps to carry out remote sensing work.
According to remote sensing information from Landsat and NOAA images, besides the meteorological factor, the flooding and waterlogging of the Yellow River and the Huaihe River are mainly controlled by modern activity tectonic. There are some hidden dangers in the lower reaches of thr Yellow River for the current river course and the river banks lack of stability. The flood overflowing from the upper to middle reaches of the Huaihe River is difficult to drain off because this area located in a modern depression. This situation constitutes a threat to some extent to Beijing-Jiulong Railway and the people living in the lower reaches of those two rivers.
Gannan in one of the most serious and most typical soil erosion area where Jingjiu railway pass through. Based on the result of remote sensing investigation, this paper discussed in detial soil erosion's types, the distribution feature as well as its development trend. The cause of soil erosion and its dangerious to Jiangjiu railway was analyzed, so it can provides the scientific basis for economic development, territory harness and evironment evalution.
The plain of the lower reaches of the Yellow River is one of the area where earthquake often occurred. The area deals with seismic belt of magnituale VI 480000km2 and magnitude Ⅷ 450000km2. According to the historical statastic data, since 1812 the Huaihe area have entered active period and earthquake action have been concentrating toward the south of Huabei. After Jingjiu railway entered the Yellow River overflow regions, it passed through Liaolan fault belt about 200 km and crossed hanging river—the current Yellow River's course in Taiqian of Henan province. In history, there were the records of Yellow River overflowed, which were caused by earthquake. Therefore seismoaction as well as the Yellow River overflow caused by seismoaction are unstability factors, the tremendous influence to Jingjiu railway and along the railway line areexert. In view of the above mentioned facts, we must strengthen defence system's construction in order to avoid the second disaster.
Jingjiu railway in Hebei section is situated in Jizhong plain, where is peripheral depression of the Cenozoic Era, and there are a lot of active tectonics. This paper gives the interpretive results of the active tectonic by using remote sensing image. In this time, a number of tectonics of NWWdirection in all region are interpreted. The paper puts the stress on the scattering feature of active tectonics and approach the active tectonic's controling function to stream system geomorphy as well as the depth of earthquake source. The active tectonics changing in the depth is infered and proved by using CTdata. At last, it points Hebei plain is one of the most important active tectonic unit where the earth's crust is thin and the earth thermal current value is high, the influence of active tectonic to the earth's steady must be considered when the industries was distributed.
This paper discusses the method of using remote sensing to assist evaluation of seismogeological environment of the Zhuhai—lingdinyang bridge engineering sites. First, active faults information was extracted from remote sensing images,second,seismicity in the area was studied,finally,evaluation of seismogeological environment of the site was made.
This paper analyses the precision of TM and SPOT images, and provides the method to use remote sensing synthetical spatiotemporal information in landuse dynamic change monitoring. The method has been used in Beijing Shunyi proving ground and the good result has been achieved.
This paper introduces the tourism resources along the Jingjiu railway line and expounds the taping of tourism resources will bring about a great advance to the economic belt along the Jingjiu railway line. At last, the good prospects of using remote sensing to investigating the tourism resources along the Jingjiu railway is looked forward.
Some preliminary results for the study project are described in this paper, for which the remotely sensed data such as the Landsat TMimage is used into the porphyry copper mineral exploration in the eastern Tibet, since the elevation of the region is very high and unaccessable by the conventional methods. In addition, there is a big potential for the copper exploration and several huge porphyry copper deposits have been, so far, discovered there. It is shown from the conventional geologic data that the mineralization of the study area is clearly controlled by the volcanic formation in the Tertiary and related closely to the immediate- felsic porphyry introsives in the Himalaya Movement. However, the results of the interpretation and analysis for the Landsat image revealed that the major mineral deposits are located in circle structures that are almostly the calderas developed in the Later Tertiary. Meanwhile, digital image processing with the Log-Residual, Mineral Indices and HSI Transformation algorithms have been also applied in this study in order to enhance and extract the alteration information related to the porphyry copper mineralization with the Landsat TMdata and most of them are correspondence with the circle structures to be found from the visual interpretation of Landsat TMimge. Then, some target areas for the mineral exploration in the study area are delineated on the base of both the circle features and the alteration information to be mentioned above.
