蒙古栎林对大气降雨的再分配规律
Rainfall Redistribution of Mongolian Oak Plantation in Harbin
摘要
Abstract
Exploring forest canopy redistributing regime of rainfall contributes to reveal water recycle mechanism of forest ecosystem.The Mongolian oak(Quercus mongolica)plantation in Harbin city was selected to study its rainfall redistribution effect and variability via 20 rainfall events in a growing season.The following results were concluded:1)the throughfall,stemflow and canopy interception in Mongolian oak plantation were respectively 197.6,62.8 and 78.8mm,which accounted for 58.27％,18.52％ and 23.24％ of the rainfall in open field;2)throughfall occurred when the outer rainfall exceeded 6.7 mm and stemflow occurred only if the rainfall exceeded 4.3 mm according to the model estimates;3)the amount of throughfall,stemflow and interception all increased significantly with increasing rainfall,while their ratios to rainfall showed different trends;4)The coefficients of variability in throughfall decreased significantly with the amount of rainfall increasing,and the two showed a negative correlation(p<0.01);5)the biologic character of Mongolian oak is beneficial to stemflow producing,thus the Mongolian oak produced more stemflow than other species did in common region.关键词
