The results showed:(1)Nitrogen addition changed the soil physical and chemical properties, enhancing the content of NO3—- N available resources in the soil, increasing the plants height and cover, reducing the vegetation light penetration. With increasing of N addition, both the species richness and the diversity decrease sharply (P 0.001).(2)N addition increased the aboveground biomass significantly (P 0.05). With increasing of N addition, the aboveground biomass increased first then decreased, and the grasses biomass increased while the forbs and legumes biomass decreased.(3)There was a significant linear positive relationship between species richness and vegetation light penetration (P 0.05), and also between aboveground biomass and soil NO3—- N content (P 0.05). The relationship between aboveground biomass and species richness was negative upon enhanced N supply.

结果表明：（1）氮素添加提高了土壤中NO3—- N等可利用资源的含量，增加了植物群落植被的盖度，减小了植被的透光率，随着施氮量的增加群落中物种丰富度显著降低（P 0.001）；（2）氮素添加显著改变了植物群落地上生产力（P 0.05），随着施氮量的增加地上生产力呈现先增加后降低的变化趋势，各功能群中禾草生物量显著增加，而杂草和豆科生物量随施氮量增加逐渐减少；（3）物种多样性与植被透光率呈线性正相关（P 0.05）；地上生产力与土壤NO3—- N含量呈线性正相关（P 0.05）；随着施氮量的增加物种丰富度与生产力之间呈负相关关系。

纤维粘连蛋白（fibronectin，FN）作为间质细胞的胞外基质成分研究较多，在胎盘的分布状况也较常见［1，2］，但对正常和异常滋养上皮的准确定位和功能的关系的全面系统报道研究未见报道。

These results, together with the structural elucidation of the purified polysaccharides described above, indicate that the α-glucans in G. lucidum don't have any remarkable immunomdulating activities, but the effects of β-glucans on immune system depend on their glycosyl residue linkages and sugar chain conformation. Further, it is concluded that the 1, 3-linked backbone, relative lower side chain size and substitution, and a high-organized helical structure are the beneficial structural features for the immunostimulatory activity of β-D-glucans. However, the 1, 6-linked backbone may induce the immunosuppressive effect of β-D-glucans.

结合各纯化多糖的结构与构象分析的结果，可以得出以下结论：赤灵芝中的α-型葡取糖不具有显著的免疫调节作用，而β-型葡聚糖的免疫作用则与其糖链结构和糖链构象有密切关系，1，3-连接的主链，较低的分支取代率和较短的支链长度及高度有序的螺旋结构是β-型葡聚糖发挥免疫增强功能的有利结构因素，相反，1，6-连接的主链却可能引起多糖的免疫抑制作用。
