- Abstract:
-
Accurate and timely information on spatiotemporal dynamics of soil loss is crucial for making effective soil and water conservation measures. By using RUSLE formula, an estimation was made on soil loss risks in Anji County of Zhejiang Province during the period from 2000 to 2012, and time series data of soil loss were thus obtained for 13 periods (one period per year). Then an analysis was made on spatiotemporal dynamics of soil and water loss by using Mann-Kendall approach. The results showed an evident trend of increasing risk of soil loss in the county during the study periods, when the area of soil and water loss obviously increased, the level of risk also showed an obvious trend of increase. Mann-Kendall approach, in comparison with spatial overlapping approach, can reveal spatiotemporal dynamics of soil and water loss more accurately and specificly. This approach can provides a new perspective on the analysis of long-term dynamics of soil and water loss.
