Objective Nowadays, high-resolution remote sensing technology has brought new changes to surveys of earthquakes, and the quantitative study of seismic faults based on this technology has become a trend in the world(Barzegari et al., 2017). An Mw 7.2 earthquake occurred in Yutian of Xinjiang on the western end of the Altyn Tagh fault on March 21 st, 2008. It is difficult to access this depopulated zone because of the high altitude and only 1–2 months of snowmelt. This study utilized high-resolution

Applications of Remote Sensing Techniques in Coal Geology

Through applied researches, the regularity of thermal infrared radiation of the coal seams has been found, a model of thermal radiation of the coal seams established, and the internal relations of the information extracted from remote sensing images with coal seams and coal measures revealed. Through a series of complete tests of remote sensing techniques such as multi-level (space, aerial and ground) synchronous remote-sensing and multi-directional, multiband and multitemporal remote sensing, the optimal procedure for applications of remote sensing techniques in coal geology has been determined. The theories and methods established in the applied researches have yielded apparent economic results and social benefits in respect to coal field prediction, coal reconnaissance, coal geological surveys and detection of geological hazards in coal mines.

APPLICATION OF REMOTE SENSING IN THE ANALYSIS OF WATER ENVIRONMENT IN ZHUJIANG RIVER ESTUARY

1. PREFACE Lingdingyang is a trumpet estuary. It accepts the runoff of the Dongjiang River, the Beijiang River, the Zhengjiang River and the Liusihe River. It also accepts a part of the runoff of the Xijiang River. Its mean year runoff is 1.742×10" M^3. In resent ten years, industry and agriculture are developing rapidly in Guangzhou City, Dongguan City, Zhongshan City, Shunde County, Panyu County. Lingdingyang’s pollution is increesing. Water quality of lingdingyang is steadily deteriorated. In order to investigate the situation of water environment of Lingdingyang, we study its static environmental capacity of nitrogen and phosphorus. LANDSAT imageries are used in the study. The concentrations of nitrogen and phosphorous is detected by convention method.

APPLICATIONS OF REMOTE SENSING IN ENVIRONMENTAL INVESTIGATION AND CHANGE ANALYSIS IN THE THREE GORGES AREA

1. INTRODUCTION The proposed Three Gorges Project, one of the biggest hydroelectric projects in the world, will dam the middle reaches of the Changjiang (Yangtze) River, the third longest river in the world, and form a large reservoir. Its impacts on environment have attracted wide attention. Entrusted by National Scientific-Technical Commission, the Chinese Academy of Sciences (CAS) was in charge of a research project on this issuse from 1984 to 1989. Tho use of remote sensing played an important role in the project considering the study area is mountainous and not convenientlv located, which makes it difficult to conduct the research onlv using conventional means.
