he land resource in an important part of land resources, in order to realize the concentration, unity and coordination to the management of the land resource, the high and new techniques must be used. According to the quantity, quality and distribution of the land resource and considering the developmental need of socialist market economy, it is important to work out the feasible plan. The paper, according to the author’s practical work experience and the survey data from the remote sensing, introduces briefly the achievements of original nation land bureau and analyses the land use problems at present. At last, the author give some constructive advices about several theoretical and technical problems that remained to be studied and solved by using the land science.

his paper deals with the development status quo and the present problems of mineral resources in China, and reviews the application of remote senisng technique in the survey of mineral resources as well as in the supervisory of the unreasonable development and the destruction of mineral resources. Meanwhile, it points out the importance and the function of remote sensing which will be used in mineral resources development, plan, managment and protection.

his paper deals with the development situation of the remote sensing technique used in archaeological studies in the past few years, and by combining with the example of archaeological studies in China it introduces the method of how the remote sensing has been used in this field. At last, it looks forward the good prospects of remote sensing technique which will be further applied in the field of archaology.

sing the information of remote sensing and combining with the sedimentary formation analysis to pick out and study chronostratigraphic interface in cretaceous period basin in the course of studying intracontinental deformation evolution about North-eastern Jiangxi Jiangnan orognic belt and filling sequence of Xinjiang basin. Since three types of chronostratigraphic interfaces (Paleostructure interface, large regional erosional unconformites and overlap interface) have been picked out, it guarantees that the analysis of basin sedimentary facies is right. We can rebuild filling sequence and tectonic evolution stage of basin according to them. The method will become a new kind of methods in the course of terrestrial basin analysis in the future. It can push on founding method system of double mapping on terrestrial basin in 1:50 000 regional survey.

he paper studies the Zhongchuan granitic mass with TM imagery in the Western Qinling of China. Under the conditions of the vegetation and loess covering, according to pixel and laboratory Spectrum, different contact metamorphic rocks were identified. The paper also discussed the control factors of exo-contacts to the gold mineral deposits.

he in-situ sampling and the on-image sampling have confirmed that in Liugouxia area the altered rocks, being closely related to metallic mineralization, are characterized by the double peaks on the reflective spectra curves (high reflection in TM3 and TM5 bands). This provides the prerequisite for abstracting the information of the alteration rocks from the remote sensing image. This paper, by studying the method of abstracting the alterated rocks information, demostrates that the method of PCA (using TM1+TM2, TM4/TM3, TM5,TM7) is the best for the information abstraction. This method can be called modified Crosta method. Among the 103 deposits located in the 9 000 square kilometers area, there are 86 deposits that have the corresponding alteration anomalies on the anomaly image is obtained by the modified Crosta method. The coincidence coefficient is as high as 83.5%. Another 115 new targets were predicted according to this anomaly image and rock types as well as structrural conditions.

ith the development and improvement of PC hardware techniques in the past few years and the continuous appearance of good quality PC softwares, the reomte sensing image processing, interpretation and mapping could be done on PC supported by some softwares. This paper, taking “Nansha Remote Sensing Survey Project” as an example, introduces the practical applications of the desktop softwares, and by comparing with other conventional ways, such as the work on workstation, image interpretation of traditional ways as well as compiling map with hands, further illustrates the advantage of adopting this new technological mothed. The result of this pratice has proved that the desktop softwares based on PC will open vast application vistas in many fields.
