Developing rainwater-harvesting and water-saving irrigation to deepen water conservancy for enriching farmers--enlightenment from investigating the rainwater-harvesting projects in Gansu Province;

A practical model—multi-level fuzzy gross assessment model, which was used to assess the feasibility of the rainwater harvesting and water-saving irrigation project,is given in this article,and the procedures for the model are presented.

This paper analyzes the present situation of water resource and the features of agricultural production of Datong City, and expounds the importance and feasibility of developing rainwater-collecting irrigation project.
