内蒙古鄂尔多斯皇甫川流域恢复草地和退化草地土壤微生物类群数量分布特征的研究结果表明:恢复草地和退化草地土壤微生物各类群数量是,好气性细菌>放线菌>芽孢型细菌>真菌;0~10cm的微生物总数超过其他土层,其垂直分布的基本趋势是0~10cm>10~20cm>20~30cm>30~40cm>40~50cm;微生物各类群中,细菌是最多的一个类群,这一结果取决于好气性细菌的数量;恢复草地各土层中的土壤微生物类群数量均高于退化草地;在恢复草地的土壤微生物数量中,好气性细菌,芽孢型细菌,放线菌,真菌为秋季大于夏季;土壤微生物数量与土壤肥力有着密切的关系,恢复草地是防止皇甫川流域草地退化,提高土壤质量,保护生态环境的重要措施。
补充资料:航迹
航迹
track
hangji航迹(tr ack)航空器航行时在地面投影点移动的轨迹。亦称航迹线。航迹的方向,是从经线北端顺时针量到航迹的去向,这一角度叫航迹角,范围是0o一3600。在无风的情况下航行,航迹角同航向相等,航迹线与航向线重合。在有风情况下航行,航迹角同航向常不相等,航迹线与航向线常不重合。在实际工作中,需要判明航迹角同航向的关系,才能掌握航空器相对地面运动的方向。(王畏)
