Relationship between Water Table Depth and EC and pH of Soil with Vegetation (Case Study: West Coastland of Maharloo Lake at Fars Province)

Maharloo Lake covers an area of 257 km2 that located on 18 km East of Shiraz city. This research aimed to investigate the vegetation of lake's western border land. At first location, geology, hydrogeology, pedology and climatology were studied. Aim of this research is relationship between water table depth and EC and pH of soil with vegetation. Because of it, in first step, vegetation types were made on the basis of geomorphology of region and then within each vegetation type, sampling the vegetation completely randomly by transect method using transect of 30 m and 3 transects per each type. In each type, sampling soil to a depth of one meter by foreseeing two depths (first depth 0-50 cm and second depth 50-100 cm) were done and soil samples tested by experiments involving saturated percentage, electrical conductivity, pH of soil and texture. Total depth of groundwater obtained using total station camera and the topographical maps and wells in the area and field studies. Finally, according to data obtained from vegetation studies, soil and underground water depth, the relationship between these factors was obtained by Pc-ordination software and by Canonical Correspondence Analysis (CCA) was analyzed.
