一、引言遥感技术已经广泛用于土地资源调查中。但就卫星遥感而言,其作用主要局限于土地利用现状调查,目前还难以满足土地资源评价的需要。土地资源评价是对土地这一复杂的地理综合体的分析和评价,其中某些因素遥感信息目前还难以反映或难以分析出,当使用计算机处理时尤其如此。然而,近年来多种信息复合处理在遥感中的应用日渐增多,地理信息系统及其与遥感系统的结合的研究日趋深入,使我们看到了利用遥感信息与地理信息系统进行土地资源自动评价的可能性。本文在此方面作一初步试验。
I. Introduction Remote sensing technology has been widely used in land resources survey. However, in the case of satellite remote sensing, its role is mainly confined to the investigation of the status quo of land use, and it is still hard to meet the needs of land resources assessment at present. Land resource assessment is the analysis and evaluation of the complex geographic complex of land, of which some of the remote sensing information is currently difficult to analyze or difficult to analyze, especially when using computerized processing. However, in recent years, the application of multiple information composite processing in remote sensing is increasing day by day. The research on the combination of geographic information system and remote sensing system is becoming more and more in depth, which enables us to see the possibility of automatic evaluation of land resources using remote sensing information and geographic information system Sex. This article in this regard to make a preliminary test.
