中文摘要	以毛乌素沙地西南缘三种典型灌丛(羊柴、中间锦鸡儿和油蒿)为对象,研究其在不同降雨量下的截留特征,并分析了降雨特征与三种灌丛冠层截留特征之间的关系。结果显示:(1)在试验期间,监测降雨21次,总降雨量为245.4mm,单次最大降雨量为41.7mm,单次最小降雨量为0.6mm,平均降雨量为11.6mm;(2)累计和最大截留量排序均为油蒿>中间锦鸡儿>羊柴,在雨量级5~10mm、10~20mm和>20mm中,平均截流率变异性分别为中间锦鸡儿(28.91%,CV=54.31%)、羊柴(5.65%,CV=52.32%)和油蒿(6.28%,CV=53.01%);(3)在不同降雨量、降雨强度和降雨时长的影响下,灌丛冠层截留量、截留率均表现为油蒿>中间锦鸡儿>羊柴;(4)回归分析与曲线拟合显示,三种灌丛的冠层截留量、截留率与降雨量、降雨强度和降雨时长分别存在幂函数关系和指数函数关系。因此,在毛乌素沙地,羊柴、中间锦鸡儿和油蒿灌丛冠层降雨截留特征存在明显差异;并且三种灌丛冠层截留受降雨量、降雨强度和降雨时长的影响程度不同。
英文摘要	The rainfall interception characteristics of three typical shrubs(Hedysarum mongdicum,Caragana intermedia and Artemisia ordosica)in the southwestern edge of Maowusu desert were assessed under different rainfall conditions,in which the relationship between the rainfall and the canopy interception of the three shrubs was determined.The results showed the following aspects:(1)During the experimental period,21 times of rainfall were recorded that the amount of total rainfall,average rainfall,maximal single rainfall,and minimal rainfall were 245.4mm,11.6mm,41.7mm and 0.6mm,respectively.(2)Among the three shrubs,A.ordosica had the highest cumulation and maximum interception,followed by C.intermedia and H.mongdicum.Among the rainfall levels of 5~10mm,10~20mm and over 20mm,the largest variation of average interception rate was observed in C.intermedia(28.91%,CV=54.31%),followed by H.mongolicum(5.65%,CV=52.32%)and A.ordosica(6.28%,CV=53.01%).(3)Under the influence of different precipitations,rainfall intensities and rainfall durations,the shrub canopy interception and interception rate were shown as A.ordosica>C.intermedia>H.mongdicum.(4)According to the results of regression analysis and curve fitting,the canopy interception and interception rate of the three types of shrubs had a power function relationship and an exponential function relationship respectively,with rainfall,rainfall intensity and rainfall duration.It can be concluded that there were significant differences in the rainfall interception characteristics of the three shrubs(H.mongdicum,C.intermedia and A.ordosica)in Maowusu desert.Moreover,the canopy interception of the three shrubs can be affected differently by rainfall,rainfall intensity and rainfall duration.
