春季

The aerobic bacteria andtotal microorganism were the highest in autumn and the lowest in winter;Theactinomycetes was the highest in spring and the lowest in winter;The rhizospherefungi was the highest in autumn and the lowest in winter, the non-rhizosphere fungi was the highest in spring and the lowest in winter.The average microorganism"s R/Sof four seasons in Eucalyptus grandis plantation is 1.40,the aerobic bacteria"s averageR/S of four seasons is 1.40,the actinomyeetes"s average R/S of four seasons is 1.40,thefungi"s average R/S of four seasons is 1.41.The uprightness distribution rule ofrhizosphere and non-rhizosphere soil microorganism in Eucalyptus grandis plantationwere the same,the trend is surface layer(0-20cm)＞middle layer(20-40cm)＞underlayer(40-60cm).Compared with the amount of microorganism in 2004, the amount ofmicroorganism in 2006 had a definite drop.

好气性细菌及微生物总数量秋季最高、冬季最低；放线菌数量春季最高、冬季最低；真菌数量根系土壤秋季最高、冬季最低，根外土壤春季最高、冬季最低；巨桉人工林三大类微生物四季的平均R／S值1.40，好气性细菌四个季度平均R／S值1.40，放线菌四个季度平均R／S值1.40，真菌四个季度平均R／S值1.41；巨桉人工林两样地根系与根外土壤微生物垂直分布规律一致，土壤微生物三大类及微生物总数量的垂直变化总的趋势是表层(0～20cm)＞中层(20～40cm)＞下层(40～60cm)；相比较2004年土壤微生物数量，2006年三大类数量及微生物总数均有一定程度的下降。

The results showed demersal biological resources in summer were richer than that in spring as well as diversity index of the community.

These samples were collected along a main street across the urban area and a mountain route from foot to the top. Results demonstrate that the main magnetic minerals in the street dust are magnetite, maghaemite and haematite with some paramagnetic minerals. Plots of Mrs/Ms vs. Bcr/Bc and Xfd % vs. X ARM/SIRM indicate that the main grain size of magnetic minerals in the street dust are pseudo single domain. The results reveal that the Lanzhou city is more polluted in spring than in summer. The main pollution sources are anthropogenic activities （81.9%） and natural dust （18.1%）, especially the former. The spatial distribution of pollution is controlled by the topography and weather conditions.

结果表明，兰州市街道尘埃中磁性矿物含量较高，主要磁性矿物是铁磁矿、磁赤铁矿和赤铁矿，并伴有少量顺磁性矿物；磁性矿物粒度主要是准单畴；市区污染春季较夏季严重，春季高频率的强沙尘暴可能带来了更多的磁性矿物；兰州市污染物的沉积和分布在很大程度上受到气象条件和地形地貌格局的影响，市区每个盆地东端高于其它地区；兰州市污染以人为活动产物为主，人为活动贡献约为81.9％，其中包含交通约22.6％的贡献，自然降尘贡献约为18.1％；特殊的地形和气象条件，使得兰州市区的大气环境容量比平原城市的环境容量小得多，进而导致严重的大气污染。
