陕南地区降雨侵蚀力分析
Analysis of Rainfall Erosivity in Southern Shaanxi Area
摘要
Abstract
Rainfall is the main dynamic factors of soil erosion in mountainous areas in China,the rainfall erosion force reflects the potential ability of rainfall on soil erosion,analysis and study on the distribution variation trend of rainfall erosivity plays an important role in monitoring,evaluation,prevention and treatment of soil erosion in southern Shaanxi.Using daily rainfall data from 7 weather stations of representative regions in recent 60 years of including Hanzhong,Lveyang,Foping,Shangzhou,Zhen’an,Ankang and Shiquan,the rainfall erosion force of each platform were computed and statistical characteristic of rainfall erosion force were analyzed. The results showed that average rainfall erosion force belongs to medium variation,southern Shaanxi rainfall erosion force gradually reduces from west to east.关键词
