Abstract: The ecological characteristics and biological community structure of AMfungi in seven provinces in south and east coast of China were studied. The resultsindicated that the species frequency and relative abundance of Glomus was the highestin mis region, while Sclerocystis ranked second. The species richness, spore densityand species diversity index were higher in four southern provinces than those in threenorthern provinces of the region. Agglomerative classification analysis showed thesimilar resultS.

Abstract: This paper deals with the regional distributions of AM fungi in the east and south coast of China. The studies were based on 278 soil samples from root zones of host PlantS belonging to 60 families in 15 soil types. Soil division and climate zone coincide in this region, and was divided into five zones. Glomus was the Predominant genus in all soil-climate zones investigated, the frequency decreased slightly from north to south; contrarily Sclerocystis in general increased from north to south. The distribution regularities of Acaulospora, Gigaspora and deutellospora were not obvious in this region. The occurrence frequency of some species seems tO relate to soil and climate conditions too.

Abstract: 由我国东、南沿海七省278个土样中的908个AM真菌种次分析了AM真菌属和种的分布和7种环境因子的关系。球囊霉属在各种环境下均占绝对多数,巨囊霉属+盾巨囊霉属则为最少。球囊霉属在各pH水平土壤中分布较均匀;而其它四属主要出现在pH低于7的土壤中;摩西球囊霉C.mosseae(Nocol.& Gerd.)Gerdemalln & Trappe在pH低于5的土壤中仍能发现。所有五属AM真菌的出现率都随土壤有机质含量增高而减少,但在有机质含量小于1.5%时出现率均稍低于1.5—3 0%;地球囊霉G.Geosporum (Nicolson & Gerciemann)Walker的孢子数与属的规律相同,而台湾球囊霉C. formosanum Wu & Chen和弯丝硬囊霉Sclerocystis sinuosa Gerdemann & Bakshi则在有机质含量小于1.5%时数量最少。五属在不同速效磷含量土壤中的出现没有明显规律;而不同菌种对土壤含磷量有不同反应。无梗囊霉属随土壤中铁含量增加而减少其出现率;而硬囊霉属在铁含量大于15mg/kg时出现率均较多,摩西球囊霉在高于25mg/kg的土壤中明显减少而台湾球囊霉则多见于25~40mg/kg的土壤中。在15个土类中,无梗囊霉属和硬囊霉属主要分布在赤红壤和砖红壤中,前者在水稻土中也较多;台湾球囊霉主要在红壤和赤红壤中,而细凹无梗囊霉A scrobiculata Trappe则在潮土和棕壤中较多。无梗囊霉属、巨囊霉属和盾巨囊霉属在轻和砂性质地中多,蜜色无梗囊 霉A. mellea Spain & Schenck主要分布在重、中、轻质地的土壤中;而细凹无梗囊霉则砂性越强出现越多。五属在野生植物宿主根区的出现率均高于栽培植物;台湾球囊霉和蜜色无梗囊霉体现了明显的上述规律,而摩西球囊霉却较多见于栽培植物根区。

Abstract: Numerical computation of tidal current is an important way to study the status of the tidal current and forecast the distribution of the tidal current. According to the requirements of the sailing competition and the geographic information of Qingdao Fushan Bay and adjacent sea, we analyze the conditions of water momentum of the Fushan Bay Sailing competition arena using the split steps finite element method to show the rationality of the site from tidal current, velocity of flow, water quality, climate and so on.The result is that the water momentum and the climate conditions of Fushan Bay and adjacent sea are content with the the requirements of the sailing competition.

Abstract: Based on the assessment of current water quality of Qingdao sailing base, using a two-dimensional diffusion model and Chemical oxygen demand (COD) as the index factor of sea water quality, we analyzed and predicted the impact of discharge on the water quality of Sailing Game area in three situations. After the reconstruction and expansion of Maidao sewage treatment plant, the water quality of Sailing Game area in Fushan Bay had been greatly improved, and the discharge COD had little effect on the water quality of Sailing Game area under normal operating conditions, where the COD concentration was within scope of National Grade I. Under the accident conditions, the COD concentration at the outlet exceeded the standard of National Grade I, the maximum area is 2674m2, but there was no area exceeding the standard of National Grade II.

Abstract: The effects of arbuscular mycorrhizal (AM) fungus (Glomus mosseae) and phosphorus (P) addition (100 mg/kg soil) on arsenic (As)uptake by maize plants (Zea mays L.) from an As-contaminated soil were examined in a glasshouse experiment. Non-mycorrhizal and zero-P addition controls were included. Plant biomass and concentrations and uptake of As, P, and other nutrients, AM colonization, root lengths, and hyphal length densities were determined. The results indicated that addition of P significantly inhibited root colonization and development of extraradical mycelium. Root length and dry weight both increased markedly with mycorrhizal colonization under the zero-P treatments, but shoot and root biomass of AM plants was depressed by P application. AM fungal inoculation decreased shoot As concentrations when no P was added, and shoot and root As concentrations of AM plants increased 2.6 and 1.4 times with P addition, respectively. Shoot and root uptake of P, Mn, Cu, and Zn increased, but shoot Fe uptake decreased by 44.6%, with inoculation,when P was added. P addition reduced shoot P, Fe, Mn, Cu, and Zn uptake of AM plants, but increased root Fe and Mn uptake of the nonmycorrhizal ones. AM colonization therefore appeared to enhance plant tolerance to As in low P soil, and have some potential for the phytostabilization of As-contaminated soil, however, P application may introduce additional environmental risk by increasing soil As mobility.

Abstract: A glasshouse pot experiment was conducted to investigate effects of th e arbuscular mycorrhizal fungus Glomus mosseae on the growth of Vicia faba and t oxicity induced by heavy metals (HMs) (Cu, Zn, Pb and Cd) in a field soil contam inated by a mixture of these metals. There was also uninoculation treatment (NM) simultaneously. Mycorrhizal (GM) plants have significantly increased growth and tolerance to toxicity induced by heavy metals compared with NM plants. P uptake was significantly increased in GM plants. Mycorrhizal symbiosis reduced the tra nsportation of HMs from root to shoot by immobilizing HMs in the mycorrhizal, sh own by increasing the ratios of HMs from root to shoot. Oxidative stress, which can induce DNA damage, is an important mechanism of heavy metal toxicity. GM tre atment decreased oxidative stress by intricating antioxidative systems such as p eroxidases and non-enzymic systems including soluble protein. The DNA damage ind uced by heavy metals was detected using comet assay, which showed DNA damage in the plants was decreased by the GM treatment.

Abstract: 通过盆栽试验研究了不同磷水平土壤接种丛枝菌根真菌Glomus mosseae对三叶草(Clover)和黑麦草(Ryegrass)生长、P浓度及N ∶ P比的影响.试验结果表明,Glomus mosseae显著提高了三叶草中P浓度和生物量,降低了植株N ∶ P比,对黑麦草植株P含量、生物量及N ∶ P比没有显著影响;在不同磷水平土壤中,接种处理对单种时三叶草中P含量的影响程度不同,以中磷和高磷水平下的影响较显著,这表明Glomus mosseae对三叶草的菌根效应在不同磷水平下并不相同;另外,两种植物混合种植情况下,黑麦草的竞争能力高于三叶草,使得其P浓度和生物量都显著高于三叶草,而接种Glomus mosseae增加了混种中三叶草的生物量和P浓度,降低了黑麦草的生物量,表明Glomus mosseae能提高混种中三叶草的竞争能力,从而改变群落中物种的竞争关系.此外,在一定磷水平下,菌根真菌的存在降低了三叶草中N ∶ P比, 这会改变三叶草的受限制方式,由受P元素限制变为受N元素限制.
