REMOTE SENSING IN THE STUDY OF LANDSCAPE STRUCTURE

Applications of remote sensing, in particular space imagery, in the study of the physical structure of landscapes are described. Special attention is paid to space imagery's capacity for instantaneous analysis of extensive areas, its potential for combined use with more traditional methods, and the multiscalar quality of the data obtained. Joint use of a variety of image products and imaging sequences provides diverse information which can be integrated for a more comprehensive understanding of landscape structure in a variety of physical environments.

浙江东部穿山半岛岸线及潮滩演变的遥感调查

穿山半岛北侧是杭州湾的外海滨部分,其水动力条件、泥沙运移、沉积过程和地貌演变复杂。根据区域遥感影像和地理地形等资料,通过综合分析研究,探讨了穿山半岛北侧岸线和潮滩的变迁过程。研究表明,上世纪50年代穿山半岛北侧岸线大部分仍处于自然演变状态,从20世纪60年代开始,岸线向海迁移基本上是由工业填海和围海造田所致。潮滩总体呈现淤长的趋势,37a来,西侧滩界外移3050m,外移速率达+82.4m/a;向东,滩界变动范围逐渐减小。潮滩的发展具有空间、时间上差异性,潮滩淤涨集中在1955～1963年和1977～1982年。     

USE OF REMOTE SENSING IMAGERY IN MULTIPURPOSE MAPPING

This paper focuses on remote sensing's role in support of diverse mapping tasks, including those of interest to soil scientists (land use, soil, and botanical mapping). It analyzes new opportunities and challenges provided by remote sensing imagery with respect to map compilation and revision: the interdisciplinary yet goal-oriented character of map themes, the large stock of data to be processed systematically for coherent information yield, the numerous linkages of map elements to be represented on a series of closely interrelated maps, and the need for standardization and a unified approach to map design and symbolization.

THE USE OF REFLECTANCE OF OIL-POLLUTED SOILS IN MONITORING FROM REMOTE SENSING IMAGERY

A method is presented whereby soil reflectance on remote sensing imagery is used to estimate the level of soil pollution by oil production operations. This method can be used in lieu of the dangerous and toxic solvents now widely employed, and has the additional advantage of applicability to much larger areas. It is based on the construction of a graph and derivative equations depicting the relationship between the spectral reflectances of soils and the soil hydrocarbon content of sample soil plots.

THE USE OF PHOTOGRAMMETRY AND REMOTE SENSING FOR FORESTRY IN GREAT BRITAIN

The Forestry Commission needs information on the woodland cover of the country, both as general assessment of all ownerships for woodland census purposes and as detailed crop data on its own forest estate for management purposes. These survey requirements are outlined and the methods used for data collection are described, particular attention being given to the role of aerial survey. The development of a digital mapping system is also covered. Finally, the potential role of other remote sensing techniques and the trials currently in progress are discussed.

APPLICATIONS OF REMOTE SENSING IN THE STUDY OF THE MOUNTAINOUS TERRAIN OF DAGESTAN

The authors explore a wide range of applications of remote sensing methods in the study of natural hazards posed by exogenous geomorphologic processes in areas of predominantly calcareous and shale-based rock in mountainous portions of Dagestan. Space imagery, air photographs, and ground truth established from field observations provides the basis for the mapping of environmental conditions with an emphasis on the extent to which mass movements and other exogenous geomorphologic processes pose natural hazards to human residence and economic activity.
