Abstract:

Analysis of balanced water supply and demand is an important basis of the planning of cultivated land regulation project. According to the irrigated characteristics of Longji terraced field, the author gave full consideration the water providing by forest and calculated every month’s water supply quantity and water requirement for Longji terraced field regulation project area. The results showed that through strengthening water conservancy infrastructure construction and improving canal-system water use efficiency in project area, the total water resource of project area met the water demand of farmland irrigation and domestic dater, the study provided scientific basis for developing Longji terraced field regulation, also provided reference for the analysis of balanced water supply and demand in similar area.
