摘要:
利用我国南方亚热带地区江西省鹰潭市农田生态系统国家实验站自建气象站1997-2003年的自然降雨观测资料，研究了不同雨强对计算我国南方地区降雨侵蚀力的影响。结果表明：试验区不同雨强计算的降雨侵蚀力差异达到显著水平，且各年降雨侵蚀力R值总趋势为：I10>I15>I30>I60，说明为了提高鹰潭地区水土流失预报精度，找出一个适合该地区降雨特征的雨强计算降雨侵蚀力是十分必要的。进一步通过对鹰潭地区3种典型类型土壤流失量与降雨侵蚀力密切相关的降雨动能E和雨强I相关分析得出15 min最大雨强是该地区计算降雨侵蚀力的最佳雨强。
Abstract:
Through the obtained materials of 1997 to 2003 in the Ecological Experiment Station of Red Soil (EESRS), Yingtan, Jiangxi Province, the rainfall erosivity (R) and its characteristic under different rainfall intensity were significantly remarkable and the tendency of mean rainfall erosivity (R) was: I10>I15>I30>I60. They all demonstrated that it was critical to establish a suitable rainfall intensity calculating R to improve the precision of prediction model of soil erosion in the area of Yingtan. Through analysis of soil loss and index R of rainfall erosivity, I15 was the best in the rainfall erosivity in the area of Yingtan.
