本文一方面通過介紹森林水文學的概念、研究進展和實際運用，分析了森林與水相互作用的特點，並從降水、截留、徑流等方面綜合研究森林植被在涵養水源、調節水量、減少徑流泥沙、降低洪峰、增加枯水期流量、改善水質等方面具有的重要功能。1. based on the data of analysis, using theories and methods of mathematical statistics, two of interception models by canopy of picea crassifolia are established as follows : the regression model on the relationship between penetration rainfall ( p, ) inside forest and total rainfall ( p ) outside of forest : pj = 0. 8245p - 1. 372 ( r = 0. 99 ) ; the model on the relationship between interception rate ( ir ) and rainfall : ir = - 10. 7111n ( p ). ( r = 0. 7524 ) the results show that penetration rainfall inside forest increases with total rainfall outside of forest in linearity, and to certain extent, penetration rainfall inside by canopy also increases with total rainfall outside ; the correlations of the interception rate to rainfall and intensity of rainfall are significant and the intercepted rate by canopy of picea crassifrlia is diminished with the increase of rainfall and rainfall intensity, and increase with the increase of canopy density
1在利用數理統計原理和方法對實測資料進行綜合分析的基礎上，建立了青海雲杉林林冠截留降水模型：林內透過雨量與降雨量回歸模型： p _ i = 0 . 8245p - 1 . 372 （ r = 0 . 99 ） ；林冠的截留率與降雨量的模型： i _ r = - 10 . 711ln （ p ） （ r = 0 . 7524 ） ；分析模型表明：林內透過雨量與降雨量呈良好的線性關系，在一定的降雨量范圍內，林內透過雨量隨降雨量的增加而增加；林冠截留率與降雨量、降雨強度之間也呈良好的關系，林冠截留率隨降雨量和降雨強度的增大而減小，隨郁閉度的增加而增大。With a decreasing cellulose concentration of casting solution or an increasing temperature of coagulation bath, the mean pore ssze becomes larger, resulting in higher pure water flux and lower rejection of bsa
隨著鑄膜液濃度的降低或凝固浴（純水）溫度的升高，膜的水通量有較大的提高，但截留率會明顯下降。This paper mainly studied the characteristics of ultrafiltration for the removal of bacteria, turbidity, and humic acid ( ha ). experiments were also carried out to examine the effects of turbidity and coagulation pretreatment on ha removal. the mechanism of uf separation was analyzed, and the uf flux decline was preliminarily discussed
