摘　　要：在水土流失严重区域发展杨梅林生态园,可以比一般治理区更能改善林下土壤有机质含量,提高土壤肥力,各种生化强度均比一般治理区强,氨化作用、硝化作用、固氮作用和纤维素分解作用分别比一般治理区提高15.2%、60.1%、91.6%、53.8%;土壤中的根际微生物数量高于一般治理区,从而加快了林内凋落物的分解,也有利于植物本身的生长和养分的吸收。Development of the waxberry ecological orchard in the regions with serious soil erosion may have better effect on the improvement of understory soil organic content and soil fertility than that of in the normal management regions. The various biochemistry intensities are higher than that of in the normal management regions,of which,the ammonification,nitrification,azotification and cellulose decomposition are higher than that of in the normal management regions with the percentages of 15. 2%,60. 1%,91. 6% and 53. 8%,respectively. In addition,the amount of rhizosphere microorganisms in the soil is also higher than that of in the normal management regions so that it accelerated the decomposition of the understory litter and it was in favor of the growth of plant itself and the nutrient absorption.
