Spatiotemporal Variation of Wind Erosion Climatic Factor in Shandong Province

Abstract:

With Mann-Kendall non-parametric test and spatial interpolation methods, the research has explored the spatial and temporal characteristics of changes of wind erosion climatic factor C within 58 years in Shandong province. The annual average C value of the province is 163.57 with the peak value occurred both in Yantai, Weihai cities and the central area. The Yellow River flood plain, which is the most serious wind erosion district, only lies between 50 ~200. The average C value has shown a significant downward trend in the entire province for 58 years, and the peak occurred in 1962 and valley value occurred in 1990. The C value has shown a downward trend in most area of the province, among which the decrease of areas centered on Ji’ning is the greatest and reach -7/a. On the Yellow River flood plain, the C value also shows a regional difference declining trend.
