Abstract

At present, DESERTIFICATION as a problem, involves many countries, especially developing countries and includes some processes that caused by natural factors as well as human uncorrect activities. Aim of this study is investigation of WATER and SOIL indices in DESERTIFICATION condition of Ayne-khosh and finally preparing DESERTIFICATION map. For this purpose, MEDALUS METHODOLOGY that prepared by European commission (1999), was used. In order to INDICATORs access, produced INDICATORs by Ahmadi et al (2005), and some of ICD modified INDICATORs was used. Finally for each of WATER and SOIL indices, eight INDICATORs were determined. Results show that DESERTIFICATION intensity is high and going to develop. WATER and SOIL indices respectively classified to intensive (1.517) and moderate (1.381) classes. In SOIL INDEX, Organic matter, SOIL texture and formation kind INDICATORs with having numerical value as respectively; 1.871.83 and 1.80, are more effectives, and in WATER INDEX, dryness, groundwater EC and decline, with having numerical value as respectively; 2, 1.78 and 1.67 are most effectives. Quantitative value of DESERTIFICATION intensity for studying area determined by weighting mean of tow indices (soil and WATER) numerical value as DS=1.385. So DESERTIFICATION intensity class estimated as critical (kind A).
