内容 研究概要:Desertification maps on their scales are divided into four classes: large scale (1: 100,000 and larger), medium scale (1: 250,000-1: 500,000), small scale (1: 1,000,000-1: 2,500,000), very small scale (1: 5,000,000 and smaller). Desertification maps contain information on types of land degradation, desertification classes, desertification aspects and other criteria dealing with assessment of land degradation. A set of desertification criteria has been developed on the basis of regional approach for Central Asia. They include quantitative data on biological productivity, wind and water erosion, soil salinization, human pressure on environment etc. Methodology of mapping includes field study, photo interpritation of aerial and space photos, reconnaissance from helicopter and literature survey. Combination of these methods depends upon map scale and general specification of project. Methodology was tested in Central Asia, Mongolia, Libya and Mali.
