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。
In the summer of 2008, three typical sample plots were selected to study the community characteristics of soil biodiversity of newly-added forests in “Green Nanjing” forestry construction. The results showed that among the three sampling sites, 1305 arthropod landfills were captured, belonging to 12 orders and 21 orders, of which Acarina was the dominant species, accounting for 70% of the total arthropods, and common or rare species were 11 Head and 14 heads. Due to the high concentration of true mites in the western section of the high-speed poplar shelter forest in Lingling Town (sample III), the dominance degree of mites was the highest while the diversity index, evenness index and richness index were the lowest. The predominant population of soil nematodes were phytophagous nematodes and food Bacteria and nematodes, while fungi, predators and omnivore nematodes were all common populations. Among the soil protozoa, flagellates were the dominant species accounting for 70-90% of the total number of protozoa, followed by the amoeba and ciliates, In about 1 ~ 5%; the newly added woodland changed the community structure of soil microorganism to a certain extent.
