By using the Landsat TMimages as main resources of information, the interpretation and the mapping of physical environment components such as geomorphy, soil parent materials, temperature, humidity and relief for the land use of the study area were taken in this paper. The marks, methods and classification of interpretation and mapping were established. Furthermore, based on the analysis of the restriction of the land use by the environment, some suggestions were given on the sustainable utitization of land resources in this area.

Based on the geologic interpretation of Landsat TM images covered the southwestern margin of Junggar Basin, and integrated with the geologic data obtained from the geologic field survey and the results of BSS JGIsimulation for hydrocarbon generation and expulsion of source rocks, this paper analyses the neotectonic deformation character of the second and third row thrust-fold zone since the end of Pliocene, formation age of anticline and thrust structures, and the relationship of neotectonic movement with oil and gas. The research results show that neotectonic deformation of the second and third row anticline zone is very intensive, their deformation starts in the end of Pliocene, the neotectonic deformation is the most intensive in the end of early Pleistocene, the second and third row anticline zone has formed in the early stage of middle Pleistocene, the peak time of hydrocarbon expulsion for the favorable source rock-Anjihaihe Fm. is later than the formation age of these anticlines. The oil and gas from Anjihaihe Fm. is probably accumulated in these anticlines. The thrust faults usually develop near the core or in the northern limb, on one hand, they provide the pathway for vertical migration of oil and gas, on the other hand, they also cause the loss and destruction of oil and gas.

Based on the 1:50000 geological mapping in the area of Sonid Zuoqi, Inner Mongolia, the working content and methods of remote sensing technology in the regional geological mapping on the scale of 1: 50000 are briefly introduced in this paper, and the role of remote sensing in geological mapping is discussed also. In addition, the future of appling RS, GISand GPSto the regional geological studies is looked forward .

It was confirmed by sampling in site and on image, that there are anomalistic characteristics of spectra (high reflection in NIR TM51.55μm-1.75μm) in the Lancangjiang Lanping Region. It provides the scientific basis for the experimental research of image processing techniques for extraction of the TM RSinformation, related to the Cu-mineralization and alteration. The best results were get by the principle component analysis. The geologic nature of the anomalies was evaluated by comparison with the geological work in Hong to jian area and by the theoretical calculation of the image sampling. Becuse of the fact,that the image preprocessing (the geometric restoration, the brightness scaling, the multivariate statistics, the optimized choice of TMchannels etc.) was accomplished for the whole region uniformly. So it is reasonable to consider, that the obtained processing technique is also applicable for the whole region. And this paper describes it with full and accurate table(4), formulse(2), graphics(4) and colour images(5).

Based on the results of reflectance spectra measurement of 120 rocks (minerals) sample, in this paper many spectral curves have been drawed and theirs spectrum character were analysed, at last, the spectral characteristics of the major rocks were sum up.

Coal spontaneous combustion is a commonly existed hazard in the coal field of the North China. Coal Fire Monitoring Information System(CFMIS) in Xinjiang, China was set up by applying the theory, technique and methods of geographicSystem (GIS). This system aims at guiding extinguishment of coal fires, providing information for making national fire fightting plans, monitoring the tendency and development of coal fires. Three classes CFMISs were established to meet the needs of administrative branches in different rank. This paper gives the general structure of these system and their hardware configuration and software composition. The models for extracting coal fire information from remote sensing imagery, calculating coal fire area, the losses of coal, the amount of released hazardous gas, the radianant temperature, the amount of released heat of coal fires and the expenses of extinguishment were developed. The characteristics and basic function of the system were presented.

Aapproach has been developed to (semi-) automatically generate integrated community unit from remote sense imagery and geographical information system. Each integrated community unit consists of three essential component, including: (1)Plant association division; (2)structured object representation; (3)patterns in communities determination. The approach has been successfully used for vegetation analysis in the Bange test area in Tibet.

In this paper, An interpretative mark of geothermal anomaly was set up based on that the vegetation effect was caused by geothermal anomaly. Its reliability was proved with remote sensing principle and the data from spectrum and infared temperature survey on the ground. Anotable result was obtained in applying this mark to the interpretation of geothermy anomaly.
