The effects of high intensity fires on soil unit weight , porosity and separate coefficient were significant 高強(qiáng)度火燒對(duì)土壤容重、孔隙度和分散系數(shù)的影響均顯著。
Low and moderate intensity fire had no or little effects on soil unit weight and porosity , which was different from that on separate coefficient 低、中強(qiáng)度火燒對(duì)土壤容重和孔隙度的影響不是很人,而對(duì)土壤分散系數(shù)卻有影響。
After yearly burning , soil moisture content , porosity , separate coefficient , capillary and field moisture capacity increased , however , soil saturated water retaining capacity and unit weight decreased 連年火燒使土壤含水率、孔隙度、分散系數(shù)、毛管持水量和田間持水量升高,而使土壤飽和持水量、容重下降。
The effects of forest fires on soil moisture content , separate coefficient , porosity , water - retaining capacity , organic matter , available n , available ca , fungi and fine root significantly varied between the years after burning . the effects of forest fires on soil separate coefficients , porosity , saturated water - retaining capacity , available mg , fine root significantly varied between the fire intensity 火燒后年限對(duì)土壤含水率、分散系數(shù)、孔隙度、持水量、有機(jī)質(zhì)、有效氮、有效鈣、真菌、細(xì)根系生物量的影響有顯著差異;火燒強(qiáng)度對(duì)上壤分散系數(shù)、孔隙度、飽和持水量、有效鎂、細(xì)根系生物量的影響有顯著差異。
