تغییرات زمانی و مکانی پهنه پوشش گیاهی حاشیه مرطوب رودخانه آقبلاغ طی 5 دهه

Riparian vegetation is a component of river system that performs certain basic functions including primary vegetative production, protecting stream banks from erosion, trapping sediments, promoting water quality, wildlife habitat and fisheris, forage for livestock, etc. In this research, spatio-temporal change of vegetation riparian area of Aghbolagh-river as an upstream of Karoon-river for 65-km was investigated using 1956, 1969, 1998 aerial photos and 2006 satellite images. Results showed a significant change in riparian area between different periods (kappa=26.55%). This change is the result of construction of dam in the upstream in 1993, alteration of riparian area to arabal land, exploitation of groundwater for agricultural usage, etc
