- 摘要：A relative perfect space technological stereo-system for earth observation has been established in China. Through more than ten years’ efforts, the 3 Scientific Technological Experiment Satellite and meteorological satellite FY-1 have been successfully launched. Their ground receiving station of the remote sensing satellites have been also founded and hundreds of image processing systems purchased. Nevertheless, the lack of coverage all over the country and real time satellite information sources still remains as a problem since the urgent needs at present are to survey the dynamic changes of water and land resources; to timely monitor and forecast the heavy natural disasters; to meet the requests of urban planning and regional development; and to carry out international exchange and cooperation to a national extent. The author appeals for taking national remote sensing causes as a systemmatic information project to fully explore the potentialities of Chinese scientists and technicians and existing instruments, to form an operational system capable of match processing, to perform further improvements to the two application systems both of space-borne and aerial-borne, and finally to make remote sensing information service network shaped. Meanwhile, the basic studies of transmission and mechanism on remote sensing information should be strengthened to improve the utilizing efficiency.

发布时间：2021-06-10 - 摘要：In the 90th decade the remote sensing will be developing even more rapidly. A situation of competition and cooperation in internationalaspect will be taking shape. The global change will be a undoubted target while the microwave remote sensing and the imaging spectrometer will be the representatives of the next generation of remote sensing techniques. In accordance with the world trend, in this paper the basic policy for development of remote sensing is discussed to strengthen the macroscopic coordination, the basic research, the development of new technology and the applications.

Based upon his erudite knowledge, in the 1960s, designing and editting the National Atlases of PRC, he founded the comprehensive geographic cartography with an advanced level. In the 1970s, developing the Computer-assisted gartograph and remote sensing application, organizing remote sensing experements,. compiling the remote sensing atlases according to his series mapping theory, Prof. Chen did his best to open up the new prospects on Geoscience and Environment Information. In the 1980s, for facing the challenges of the information era, Prof. Chen originated the geogrophic information system research, which was helpful for planning, management and dicision-making at national, regional and local levels. All of these did have far-reaching effects.

Most of the cultivated fields were scattered in broken pieces, which, varying in their different pattens, mix up a large quantity of non-cultivated components. And therefore, it is difficult to measure the accurate areas under cultivation even with larrge scaled data. In order to make thorough investigation, the systematic methods were adopted creatively which includes （1） taking sampling strip aerial photographs; （2） calculating the value of non-cultivation coefficients of sample fields in the infrared colour air-photos by digital image processing system; and （3） Setting up the non-cultivation coefficient indexing table in different geomorphologic conditions and types of cultivated lands, etc. The methods that have been spreaded in the investigation of whole Tibet, have improved the investigation accuracy, shortened the time and redused the expens of manpower and funds. The study also provided efficent methods to investigate the cultivated areas in other mountainous regions in China.

发布时间：2021-06-10 - 摘要：In this paper based on temperature difference for forest area, average temperature of fire areas and the supposed signal noise ratio is satisfied for discreteness, The detectability of airborne and satellite （NOAA） remote sensing have estimated. The calculated results agree well with field expereiment by remote sensing image checkout. Therefore, using 3-levels （satellite, airborne, and ground） remote sensing can be to complement each other for early surveillance of forest fire.

发布时间：2021-06-10 - 摘要：In order to determine the optimum scale and band of forest aerial photography, determine-the enlargement of photo, interpretation in the experimental sites of Nankunshan, Guangong province carried out the following tests, namely determination of the spectrum of ground objects, multiple spectrum and colour infrared photograph in different scales, office interpretation, field survey and complex analyse. This article discussed the influence of aerial camera, film, coefficient of reflection of object spectrum and photographic displacement on resolving power. It also estimated the resolving power of photo image in Nanjunshan with the experimental relationship-formula and illustrated the interpretation in room and field survey. The breif conclusions are as follow: 400-800um in green band is the best for aerial forest photograph. The resolution of photo for forest interpretation is enlarged to 3.5 line/mm. If new type camera and film with high resolving power are used, photo-scale for classfication of forest resource will be decreased to 1:48000.

It takes the several kind of experiments as the instances of utilizing auxiliary data and image data composite techniques. The results have been evaluated by comparing those with the results of experts’ interpretation according tot the on-the-spot surveying records. It shows us that it is flexible to use this kind of remote sensing dato for resources investigation, and one can get the optimum effects by employing Landsat MSS biomass index. DTM image, stope and its orientation data.

发布时间：2021-06-10 - 摘要：In middle reaches of Hong Shui River, the basic structural net is constituted by the junctions of NW and NE faults. In neotectonic movement period, the region around power station became a relatively independent active body due to segmental relive of the NW, NE faults and Feng San fault block.The results from analysis of R. S. information combining with lithofacies-paleo-geograpic map and distribution of Hg mineralization show, that the Ya Du to Zi Yun deep-large fault （NW） was not included into the Feng San fault block in the neotectnic movement.Ba Yu region is 15 to 20 km distance wide from long Tan power station in fault block inside. Luo Xi active fault runs throughout this region, and the lighter earthquake is 4.6 level in recent period. This is a special region in the fault block inside which was located at a turn forward position of structural major axis of Le Ye large ring structures, the structural stress possibility concentrated at this area.Earthquake centers had closed relationship with the junctions of small ring faults. But this area is a relatively separate one, the small earthquake appeares frequently, the structural stress can be easy released, so there is no possibility to make a strong earthquake. This area has a good structural stability. But it must be carefule pay more attention to the earthquakes from reservoir stress.
