文摘Through comparatively analyzing on stand biomass,soil physical and chemical properties,hydrographical characteristics of different patterns of Michelia fujianensis and Chinese fir when 5 year old,the results all shows that those of row mixed stand of Michelia fujianensis and Chinese fir were the best,those of the unmixed stand of Chinese fir the worst. Compared with the unmixed stand of Chinese fir,the stratum biomass,total biomass increased by 22.47 t·hm -2 and 33.44 t·hm -2 ;the soil (0～20 cm) volumetric weight decreased by 0.253 g·cm -3 ;the content of soil (0～20 cm) organic matter,total N,total P increased by 7.576 g·kg -1 ,0.097 g·kg -1 ,0.135 g·kg -1 ,respectively;and stand water conservation increased by 99.53 t·hm -2 ·a -1 in row mixed stand of Michelia fujianensis and Chinese fir.
