Abstract：Terrace indexes of water storage and sediment trapping have been analyzed and confirmed according precipitation condition and terrace's quality in the loess hilly-gully region and loess gully region based on the promise and philosophy of the terrace index of water storage and sediment trapping, combing the physical circumstance of different typical region. The results showed that the index of water storage is larger in loess gully region than in other regions, and the storage benefit of high-class terrace in wet year, additionally, the variation amplitude of the water storage with variation precipitation in the region is higher, but the index of water storage in the second sub-region of the loess hilly-gully region is least. The maximum index of sediment trapping mostly appears in the first sub-region of the loess hilly-gully region and the second loess hilly-gully region, especially in all terrace in wet year or first and second terrace in normal year, which is 20～70t/hm2 larger than other kinds. Index value of sediment trapping in loess hilly region is minimum among three regions.
