日降雨量

主分量分析和偏相关分析表明，影响树干径向生长的气象因子可划分为3类，其中日降雨量、日最低气温、日平均太阳辐射和日平均空气饱和差是影响树干径向生长的主要因子。

Principle Component Analysis and Partial Correlation Analysis indicated that the meteorological factors could be classified into three groups , and daily precipitation , minimum daily temperature , average daily solar radiation and average daily vapor pressure deficit were four significant factors to determine daily stem growth .

在日降雨量10&70mm间，日降雨引起的土壤流失量差异较大，间种作物覆盖地表，对于10～70mm日降雨强度的土壤侵蚀力且有重要的抗蚀意义。

Intercropped plant covering surface land is important for erosion control among the 10 to 70 mm rainfall daily .

据分析，日降雨量大于29mm且10分降雨量大于9mm，都可能导致泥石流发生。

According to the analysis , rainfall exceeding 29 mm in a day and 9 mm in 10 minutes may lead to the generation of debris flow .
