| 摘 要： | 对华南赤红壤丘陵坡地不同侵蚀部位土壤微生物主要生理类群进行了对比分析，结果表明：除解钾菌和纤维素分解菌外，芽孢杆菌、氨化细菌、解有机磷菌和解无机磷菌都随着植被的减少，侵蚀程度的加剧，其数量显著下降；除解钾菌因多个部位未检测到而没有明显垂直分布规律外，其他主要生理类群数量均为表层0～10cm多于10～20cm；水土流失破坏了土壤微生物原有生理类群结构，减弱了微生物在维护与提高土壤质量中的作用。

| Abstract: | It has been analyzed the soil major microbial physiological groups on different erosion position of hilly slope in the lateritic red soil region.The results show that except potassium bacteria and cellulose-decomposing microorganisms,the bacillus,ammonifying bacteria,organic phosphobacteria and inorganic phosphobacteria declined significantly with intensifying of soil erosion and vegetation destroyed.Except the potassium bacteria which did not appear the vertical distribution regularity due to the not been ... |
