The multidate and multistage satellite images and airphotos are used in the study of the deterioration of water environment in East Taihu Lake. By combining multidate images of RS with the data of water level on-the-spot, the three-dimensional analysis of lake basin is suggested, and the interpretations of developments in flow behavior, water quality, aquatic plants,and in the engineering of reclamations, dikes, canals, and floodgates have been made. It is believed that the deterioration is one of the main factors of , the grim situation of flood which is increasingly serious in that area. In 31 years (1954-1985), because of reclamation and silting, the area of the lake had been reduced to 66%, the total volume reduced to about 30%, and the flood storage had been reduced to about 60%, in addition to the drainage capacity reduced to about 60-70% in the high-water season, that’s caused by diked marshes, silt dunes, and reeds. The deterioration of East Taihu Lake also related to the rapid breeding of aquatic plants, and the eutrophication may arise. It is estimated that East Taihu Lake will be separated from the main body of Taihu Lake by 2000-2010, owing to the growth of Dongjiaozui silt dune, and as a result, the Taipu canal which is the main drainage project of Taihu Lake will lose its efficiency. A tentative idea of synthetical scheme including both engineering and ecological project is proposed.

Using computer image integration technique, the multiple geoscience information such as geological, remote sensing, hydtogeological, geophysical and geochemical informations are comprehensively processed The technique consists of the information input, registration, interpolation, and the enhancement, decomposition, abstraction, classification, overlay and combination process procedures. This technique has been tested on Shengyuan Basin. The Geological environment of the basin was studied by image enhancement and overlay technique. It is suggested that the basin was a volcanic centre of central eruption during the late jurassic and was superimposed by polygonal block-faulting during Cretaceous, forming a ring-block model of ore-field structure. The U, Th, K distribution pattern and its geological. significance have been analyzed using the decomposition and overlay technique of image information. It has been pointed out that the above pattern .is. controlled by the stratigraphic-structural factors, esp cially the high-content field of uranium, besides the NE and EW trending faults, the SN trending. fault-system is of great: importance in controlling the distribution of uranium in the region. On the basis of compositing and abstracting the prospecting criteria the target areas have been preliminarily selected. An information classification was used for the general evaluation of uranium resources in Shengyuan Basin With the help of the information procesing technique on computer some new insights about basic geological problem in this previously well-studied region have been obtained. Six promising areas have been selected and tested. Based on the research work mentioned above, a comprehensive technique system of multiple geological information image integration for uranium resource evaluation has been preliminarily established.

The inventory of accurate area of farmland is one of the major tasks for land use investigation and detailed land investigation. The normal method is in situ measurement, and the work amount is enormous, with huge employment of manpower and high cost. This paper introduces a new effective method to measure and calculate farmland area by using aerial remote sensing technique. The method establishes regression equation of linear objects on air photos to revise the values that are directly measured on air photos for various patches of farmland with a surveying magnifier, and thus accurate farmland areas could be obtained. This method can. satisfy the demand for accuracy of detailed land invertigation with large scale air photos, save large amount of cost, and greatly elavate survey efficiency. The method allow indoor checking and revison for each patch of farmland.
