- Study on Rainfall Erosivity Index-R and Its Spatial Distribution in Xiamen
- 分类号:
- S157
- 摘要:
- 根据福建省降雨侵蚀力指标R值，对厦门市某一雨量观测点1996~2002年7年的所有大于10mm的次降雨资料进行回归分析，建立了R值与相应月降雨量F的关系式，在该市其它观测点的运用和分析后，发现采用该公式来估算厦门市降雨侵蚀力R值更为合适，依此公式计算厦门市R值，并进行数据结果的空间分析，探求R值变化规律，为该地区水土流失的调查、规划及有效防治提供基础数据和决策依据。
- Abstract:
- The study was to estimate the rainfall erosivity index-R in Xiamen city and analyze the spatial distribution. Continuous 7-years precipitation data from a weather station in Xiamen was used, the results indicated the equation was fit for Xiamen. With the equation, the erosivity indexR was calculated. Spatial distribution of precipitation was analyzed by using ArcView software, which provides scientific base for soil and water conservation planning and soil erosion preventing in the area.
