TMband 6 of Landsat can measure the differences in radiation temperature of ground surface features. Based on this capability, the IHStransformation was applied to put-out heat-islands of Naming City. Some maps which comprehensively reflect the heat distribution of Naming city in summer season hay. been obtained by using the, TMhand 6 and band 3 data. The results Prove that satellite remote sensing, is a good tool for research on heat-island effect and estimation of the environmental quality of city.
In this paper, the methods of applying NOAA-AVHRRdata to monitoring vegetation ecology environment are discussed, The way and step of making vegetation index distribution chart are put forward, which has been used to monitoring seasonal variation of vegetation in Zhejiang province. Shaoxing county is taken for example, quantitative and qualitative analysis are carried out based on vegetation index charts of typical seasons , and some important, results are obtained.
According to the interpretation principle of the color infrared aerial photograph, the interpretive methods and marks of the first, second and third grade were used for surveying irrigated fields. And the growth-decline of salinized boils was analysed using aerial Photograph taken during 1980 to 1987, in Dinxiang area-one county of xinding basin.
The process of discovering gold deposit, and the role played by remote Sensing image feature .and the recognition of metallogenic geology information are described in Qiaben, the nothern of Xinjiang. In the region lacking the information summed up by prede-Cessors, a target area having a fair reserve of gold deposit is predicted through analysis of remote sensing image, integration of remote sensing information;and the others, and the verification of engineering. It is showed that the way which is based on the remote sensing interpretation. and with the aid of the integrative analysis using the knowledge of geology and study of ore deposits as well as .geophisic and geochemic data is rapid and efficient for finding gold deposit.
Throng the studies on the seismic region (ML=73/4) shaking in 1947 at Dart Qinghai with the multitemporal aerospace remote sensing data, It was showed that the NWWlinear structure in the area played a dominant role in Dari’s earthquake, and the near EWblind fault appeares on the enhanced Landsat image of Sang Rima basin, Dart, and the ring image of Pingding mountain was considered to be a huge concealed rock mass with the aid of the aeromagnetic surveying data. According to the Dari’s seismic structure inferred, the seismic process can be explained well, and the basis for determining macroscope epicentre was provided.
For a comparative evaluation of multi-image on geological interpretation, the wangpingchun is selected as a typical area. The applicable condition of the color infrared aerial photograph, side- looking airborne radar image and different Landsat images were pointed out. The interpretable advantages and deficiency of the different images are analysed.
The statistical analysis was done for 177 circular structures interpreted from the remote sensing images of northwestern Guangxi Autonomous Region. The value feature of circular structures and the relationship between the circular structures and the gold minerogenesis were studied. The informations content of circular structures was calculated. The contribution of circular structures to find gold deposits was estimated using the "probability model". The statistic analysis result of the relationship between the circular structures and minerogenesis showed the deposit-finding probability in the areas of circular structures is 50 times than in the areas without circular structures. So, the circular structures in northwestern Guangxi Autonomous Region should be the favourable mark to find gold deposits.
