Abstract: The Hani terrace in Yunnan Province is a kind of montane agricultural landscape, being famous for its large area, wide distribution, astonishing construction, and infrequency in the world. In this paper, surface water was sampled
from the Quanfuzhang basin in Yuanyang County, with the nitrogen and phosphorous contents determined. In the terrace surface water, both the total nitrogen (TN) and total phosphorous (TP) contents and their spatial heterogeneity were the highest in spring; in the stream water in terrace region, the TN and TP contents were the highest in summer, and their spatial heterogeneity differed with sampling time; while in the stream water in forest region, the TN and TP contents were the highest in summer, but the spatial heterogeneity of TN and TN had greater differences. As a whole, this basin was poor in nutrients, and the nutrient contents changed with seasons. The spatial variation of the nutrient contents was in the order of terrace surface water > river water in terrace region > river water in forest region, which indicated the complex spatiotemporal changes of nutrient in terraced agriculture.
