This paper discussed the principle of land use status survey by using infrared aerial photographs and the methods of identifying land use categories. The principle and methods were then used to analyze the characteristics of current land use in Yudong Plain, to clarify the problems existing in land use in this region. Suggestions about land use in a comprehensive way were proposed.

The land use change in Wuxi urban district was analysed with the inter- pretation of remote sensing data for three periods since 1949,combined with social and economic information of city development. The urban land use scale and structure as well as the characteristics of city layout evolution and suburban land use change were expounded. This paper also probed into the matter about how to use land resources reasonably.

According to Landsat image, there is an ancient proluvial fan between Shizuishan, Ningxia and Wuda, Inner Mongolia, which is cut through by the Yellow River. The investigation in the field proves that the three stage terrace of the Yellow River is proluvial erosional terrace in late Pleistocene. So, the Yellow River growth was after late Pleistocene.

This paper introduces the methods of extracting information about the disaster of underground coal fire using digital image processing techniques on S₁₀₁ Image Processing System. The emphasis is on the image processing techniques used in extraction of ground surface burning area information from the multidate airborne and space thermal infrared remote sensing images and on their application affect.

Remote sensing information is economical in petroleum and natural gas survey. This paper introduces two remote sousing methods to look for hydrocarbon reservoir. 1. The hydrocarbon micro-seepage information was extracted from TMdata with the spectra and image processing to detect petroleum reservoir. The application results in North China were presented in this paper. 2. Application of residual index of linear bodies to detect the local structure of petroleum reservoir. This method is special to study the buried local structures which are deep and hard to find because of weak response. The residual index analysis method of geographic, geomorphic and geologic linear bodies was used to detect the local structures of petroleum reservoir. This paper introduced the application results in carbonatite area.

This thesis deal concisely with the basic characteristic and interpretation marks of X-band synthetic aperture SCARimages. By means of interpreting SLANimages of semi-overcast and overcast region of dry-gebi in the east part of Xin Jiang, the subsurface structures, such as fold, fracture, ring- structure and so on, is effectively studied and the information about that region is enriched. as a result, a further point is raised that the Longitudinal eune of KUMUTAGEis a rising neotectonic.

In this paper, the DEMapplication to the study of waterlogging damage in Jianghan plain is demonstrated in principles as well as methods, The waterlogging mechanism and its agroecological characters are analysed, and the loss estimation formula for rice due to waterlogging is developed. With the support of DEM, the rice loss of waterlogging is estimated in the test region

The huge information content of the remote sensing image bring on the great difficulty in the storage.record.transfer and processing for the image. Particularly, when the image processing operate in a micro-computer, the problem is more projecting. Technology of the image compression coding is a main way to resolve the problem. However, a number of the common in methods for image compression coding that are introduced by the literature, most of them bring about the reduction of the information content, a number of them can't suit the remote sensing image, otherwise, the realizing of methods is difficulty. This paper presents the method of adaptive mixed compression coding for image. The method absorbs the advantage for the several means of compression coding. It carry on the compression coding for an image, base on the spatial correlativity and local even level of the image. The method is both to realize easily and has the better effect for the image data compression. Generally, the compression ratio can attain about 2 .0. The method,of adaptive mixed compression coding belongs the redundance compression. It doesn't bring about the information to reduce.

This paper simplifies the related Fluid Mech. formula on the basis of experiment result, the static state water thermal model is built up and related program is given. The maxium error between measuring and calculating is 0. 66℃ and the average error 0. 18℃. This model can be used in remote sensing reconnaissance of water pollution and other related fileds.

This paper introduces mainly the method and results of measurement of surface radiance temperature and ground temperature in different depths for research on the mechanism of thermal anomaly induced by ground oil-piping. The optimum time and season for thermal infrared scanning imaging is analysed based on the results of measurement. The anomaly intensity and vertical attenuation amplitude of ground temperature are discussed in it. The temperature gradient and thermal flow value are computed. The changing few of thermal transmission caused by ground oil--piping at night is discussed.
