Large-scale irrigation districts are the important scale agricultural and commodity grain production bases in the world. The total amount control and multi-dimensional critical regulation and control technology of water resources in irrigation districts have become the key problems of food security and water safety in China. In this paper, we mainly research on water recourse of the Hetao irrigation area in Inner Mongolia, establish the multi-dimensional attributes index system of water recourses in Inner Mongolia Hetao irrigation district, analyze the internal relationship of attributes in the same dimension and between the multi- dimensions, adjust and improve the original index system, and further put forward the specific adjusting and controlling index of water recourses for each dimension. The purpose of all these works is to provide technology support to establish the multi- dimensional critical control model of water resources in the Hetao irrigation district, ultimately achieving the goal of social and economic sustainable development in the irrigation area.
