| 摘 要： | 于2008年夏天选择三个典型样点对"绿色南京"林业建设新增林的土壤生物多样性的群落特征进行研究。结果表明:在三个样点中,共捕获地表凋落物节肢动物1305只,隶属12纲21目,其中真螨目为优势种群,占总节肢动物的70%,常见种群或稀有种群分别为11目和14目。由于机场高速杨树防护林秣陵镇西段(样点III)真螨目的高度集中,其优势度最高,而多样性指数、均匀度指数和丰富度指数均最低;土壤线虫优势种群为植食线虫和食细菌线虫,而食真菌、捕食、杂食线虫均为常见种群;土壤原生动物中,鞭毛虫为优势种群,占原生动物总个体数的70～90%,其次为变形虫,而纤毛虫比例最小,在1～5%左右;新增林地在一定程度上改变了土壤微生物的群落结构。

| Abstract: | In summer,2008,three typical samples were selected to study the effect of new planted forest of "Green Nanjing" on soil biodiversity.The results showed that total of 1306 soil arthropods,belonged to 12 classes and 26 orders,were collected in three samples.The acariformes,accounting for 70% of total arthropods,was the dominant group,while others were the common or rare groups,and the common and rare groups were 11 orders and 14 orders.About the soil nematodes,the plant feeders and bacterivores accounting for 41% and 37% respectively,were the dominant groups,the other three nematodes including fungivore,Predatore,and flesh nematodes,were the common groups;All of the soil protozoa,flagellate was the dominant group,ranged 70-90%,followed closely by amoeba,and the ciliate accounted about 1-5%.To some extent,the forest soil changed the soil microorganism community structure. |
