Assessment and mapping of desertification sensitivity in central part of Iran
Journal Title: International journal of Advanced Biological and Biomedical Research - Year 2014, Vol 2, Issue 5
Abstract
Knowledge of behavior climatic indexes can be help to planning future programs Bahabad study area in the eastern part of the province of Yazd with a hot and dry climate, high potential evapotranspiration and low rainfall has a high potential for desertification. The aim of this research is evaluation of classification intensity by IMDPA model with emphasis to climate criteria. The indices included mean annual precipitation; UTI aridity index and length of drought period were applied for preparing of intensity map of desertification by using Arc Gis software .Scores of indices were recorded in different study units. At last, using the formula, CI= (a× b ×c) 1/3. Final Score of climate criteria (CI) was determined in the study area based on IMDPA. In this model, desertification potential classes are moderate, and high. The result showed that 68.42% of the study area is considered as medium, and 31.58% of the study area is on the high desertification intensity class.
