Survey and Analytic the Role of Critical Center and Wind Erosion in Vacate of Rural Settlements with Using GIS Technique in Zabol

ABSTRACT: Sis tan region is too dry region and the weather has an important role in dispersal rural settlements and also attraction population or vacates these settlements. Mainly in formation rural settlements several factors can be effective which consist of natural and human factors which in this between these factors naturally wind erosion Sistan propellant abound create some problems for rural settlements in this region.
