It is essential to achieve sustainable and comprehensive development in combating desertification issue. In relation to the mentioned case, investigation and ranking of current status of development indices of combating desertification process in different areas, is crucial which will determine the level of, budgeting and manpower polices. Therefore, numerical taxonomy model was recognized as a suitable tool for determination of ranking and classification of combating desertification indices. The study model is used for investigating and ranking of existing situation of combating desertification in the urban areas of Yazd province during the period of 2002-2007. The model evaluates
development and extension of combating desertification indices in the urban areas using analytical structure and the final results are shown as the assessment Maps.
