利用信息系统技术编制土壤退化图,已是势在必行的一项科研工作。由于世界性土地承载的压力不断增加,森林的滥伐,促进了土壤的严重退化。而不同地区,不同土壤的退化过程和程度是不一样的。从而使土壤工作者和资源管理规划人员产生一个强烈的要求:建立一个适时、有用的土壤—土壤资源数据库,去开展土壤监测工作。本文叙述了供土壤退化评价用的土壤—土地数据库的建立、土壤退化评价的方法、过程等现代信息系统技术。
It is imperative to use the information system technology to prepare the soil degradation map. Due to the increasing pressure on the world’s land, deforestation has promoted serious soil degradation. Different regions and different soil degradation process and extent is not the same. As a result, there is a strong demand from soil managers and resource planners to establish a timely and useful database of soil-soil resources to carry out soil monitoring. This article describes modern information system technologies such as the establishment of a soil-land database for soil degradation assessment, methods and processes for soil degradation assessment.
