The article establishes the ecosystem evaluation system of saline-alkali land in Shaanxi Province by using soil index, environmental index, biological index, productivity index and sustainable development index, and uses entropy method and analytic hierarchy process to determine the weight of index evaluation system. Finally, the practice and evaluation of the saline-alkali land ecological management method in Shaanxi Province was carried out, and it was found that the establishment of the index system has theoretical and practical significance.
