%X Arbuscular mycorrhiza (AM) fungi are the most common underground symbiosis. They can form vesicles and arbuscules in the roots of about 80% of plant species. In this paper, using the arbuscular mycorrhiza’s colonization as an evaluating indicator in combination with other experimental indicators, we composed a system of evaluating various indices to analyze desert soil conditions. A fuzzy optimization system model was introduced to analyze the experimental results. The results showed that the soil quality was Yulin>Ecology Station>Yanchi>Shapotou>Dingbian. ‘μi’, an indicator of soil quality, was the greatest in the topmost layer of soil, in the 0–10cm soil, at the sampling sites Yulin, Ecology Station, Yanchi and Dingbian. However, at Shapotou the maximum value of μi was found in the 10–20cm soil layer. The weight value of the AM fungal index ranged from 37% to 95% at different sites.
