مقایسه ی کارایی مدل اکولوژیکی مخدوم و فائو برای برآورد توان اکولوژیکی کاربری کشاورزی و مرتع داری (مطالعه موردی: حوضه آبخیز آبهار خوزستان)

This study has been done to compare the performance of FAO and Makhdoum ecological model to estimate the agriculture and rangeland ecological capability in the Ab_ Bahar Khuzestan watershed. After collecting the required data in the Makhdoum method, the analysis, compilation and evaluation of capability were done systematically. Then, after collecting the information in the FAO method, verification of the limitations and levels of capability of each component of the land unit, the potential capabilities map of the land was created. According to Makhdoum method, ۲۳.۳۳% of the area has a grad number ۲ capacity for agricultural use and ۲۲.۲۷% has a grad number ۳ capacity for the same purpose, and ۳۳.۳۳% has the power of grade ۱ (۴th class model) for land management purposes and ۲۱.۴۱% have grade ۲ power (model ۵th grade) for landing use. According to FAO method the ۱۱.۶۶% of total of studied area has the Class IV for irrigated agriculture and ۱۱.۲۶% percent for dryland farming in class IV and the ۷۷.۰۸% percent of rangeland are suitable for users. According to all obtained data, and fit the two methods roughly, ۳۵ percent of the area has suitable potential for agricultural use and the remainder, about ۶۵ percent of the total area has suitable for rangeland management. Also, in the FAO method, the amount of suitable land for ecological capability for agricultural use is less than that of Makhdoum's systematic analysis method and Instead, the same level has been added to the level of rangeland management use.
