摘要:
依据有关降雨侵蚀力的计算方法，利用重庆市81个测站连续10年的降水资料，对重庆市不同地区的降雨侵蚀力R值进行了计算，并在ArcView软件支持下对所得结果进行了系统的分析、研究。结果表明：（1）重庆市降雨侵蚀力R值的月自然分布在不同区域间差异明显，且月R值的年内动态变化显著；（2）年R值在年际变化上具有两端低中间高的特点，在空间分布上具有东高西低的特点。在全面地揭示了重庆市降雨侵蚀力（R值）的时空分布特征的基础上，为如何有效防止重庆市水土流失提出了有益的建议。
Abstract:
According to the continuous rainfall data of ten years at 81 stations, the R value of different areas in Chongqin City were calculated. A systematic analysis and research on the result was made based on the support of ArcView software. The results show: (1) Sharp differences of R value of month exist among different areas, and a notable dynamic change of R value during a year also exist in Chongqing City; (2)The Cv of R value of year is higher in middle area than that in west and northeast areas, and the R value of year is higher in east areas than that in west areas. Based on a fully discussion of the temporal and spatial characteristics of R value of different areas in Chongqing City, some good advices, for how to prevent soil erosion effectively in Chongqing City, were finally made.
