Study on the Exploitation of Agricultural Water Resources in Sichuan Province

From the broad sense of water resources, the quantity, quality and distributive characteristics of agricultural water resources in Sichuan were discussed in the paper. The results indicated that agricultural water resources with 4?113.9 × 10 8?m 3 are 72.09?% of total water resources in Sichuan. Soil water resources are one of the major sources because they are 36. 57?% of agricultural water resources. Soil water resources of cropland, forest land and pasture land are 506. 8 × 10 8?m 3, 636. 1 × 10 8?m 3 and 423.4 × 10 8?m 3. The utilization of agricultural water resources was confronted with ecological degradation, low use efficiency and deficit of water conservancy projects so this paper puts forward some ways to optimize disposition of agricultural water resources, build new water conservancy woks, adjust sowing times and economize agricultural water etc.
