In this dissertation, four aspects of ECM fungi were studied in a subtropical forest, a ECM fungi identification and biodiversity estimation, using morphological and molecular ways; b genetic structure of ECM fungi population, taking two case studies; c structure of ECM fungal community, based on sporocarp and plant investigation over-ground; and d growth response of host and non-host plant to ECM fungi inoculation.

由于外生菌根真菌的宿主植物常常是一些生态系统的优势种和建群种，并且这些真菌还参与了许多森林生态系统的有机和无机元素循环、物种的竞争和共存、生物多样性的维持、生态系统的演替等过程，因而对外生菌根真菌的研究有助于对这些生态系统维持和演替机制的深入理解。

Arbuscular mycorrhiza was the widespread reciprocal benefit symbiont in the natural ecosystem, this study aimed to introduce the AM fungus and the host plant as well as the effect of environmental condition on the formation mechanism, and propose several questions which need to be paid attention to both in current domestic and foreign research.

丛枝菌根是自然生态系统中广泛分布的互惠共生体。主要介绍了AM真菌和宿主植物以及环境条件对其形成机制的影响，并提出了当前国内外在丛枝菌根生理生态学等方面研究需要注意的几点问题。

Arbuscular mycorrhiza is a product of the adaptive coevolution with arbuscular mycorrhizal fungi in the long-term life process, and is a kind of beneficial symbiont of plants. It can promote the resistance ability of plants to poor surroundings, and accelerate plant growth. The seedlings of wild jujube were used as materials in this research.

丛枝菌根(Arbuscular Mycorrhiza，AM)是植物在长期的生存过程中，与丛枝菌根真菌(Arbuscular Mycorrhizal Fungi，AMF)一起共同进化的结果，是一种有益共生体，它的存在有利于提高植物抵御不良环境的能力，促进植物生长。

On the base of study on arbuscular endomycorrhiza of Alnus of Changbai Mountain and nitrogen-fixing woods of Northeast of China, the paper attempted to reveal the DNA molecular polymorphism of the symbiotic arbuscular endomycorrhizal fungi for the effect that make better use of the fungi resource.

本项研究利用分子生物学技术和研究方法对中国吉林长白山地区非豆科固氮植物以及东北地区固氮树木的丛枝菌根真菌DNA分子多态性及其与宿主植物之间的相互关系等进行初步研究，旨在利用分子生态学理论和研究方法揭示丛枝菌根真菌多样性及其与宿主植物之间相互适应和协同进化的一般规律，为更好地保护和利用这一重要的微生物资源提供理论依据。

Arbuscular Mycorrhiza is one of the most broad mycorrhizal, it can enhance plants' ability of absorbing.

丛枝菌根是分布最广泛的一类内生菌根，它可以促进植物对水分的吸收和利用，提高植物的抗旱能力。

With the development of mycorrhiza and phytoremediation techniques, the application of arbuscular mycorrhiza to enhance phytoremediation efficiency has attracted more and more attention.

随着菌根研究和植物修复技术的发展，利用丛枝菌根强化重金属污染土壤的植物修复逐渐受到人们的重视。

Arbuscular mycorrhizal fungi occures in different environment The distributing of AMF contain difference because of the vegetation types and the environmental factors.

丛枝菌根真菌在自然界分布极为广泛，由于植被类型和生态环境的不同，使得丛枝菌根真菌的分布存在很大的差异。

A total of 112 plant species from the grassland and desert of Ordos were collected and examined, of which 108(96.43%) were infected by arbuscular mycorrhizal fungi.

本文以内蒙古自治区鄂尔多斯地区为研究背景，开展丛枝菌根植物和丛枝菌根真菌多样性及其分布的调查研究。

Vent were studied in this experiment based on scanner-based image analysis. The results showed that drought and AM inoculation had a large, significant effect on plant development. Biomass, total length, surface area, volume, number of root nodes, average diameter and fractal dimension of root system in Broussonetia papyrifera Vent decreased with the reduction of soil moisture, while they were increased by AM inoculation. Special root length in non-AM plants increased when soil moisture was reducing, but it was decreased by AM inoculation.

结果表明，土壤水分状况和接种菌根真菌对构树幼苗生物量积累产生了显著的影响；构树幼苗根系干重、总长度、表面积、体积、根节数目、根系平均直径和分形维数表现出随着土壤含水量的降低而降低，接种G.mosseae则使得该参数比同等水分条件下显著升高；未接种植株比根长SRL表现为随着土壤含水量的降低而升高，接种G.mosseae则降低了同等水分条件下构树幼苗的比根长；土壤水分和接种G.mosseae同样也对根节平均长度产生了影响。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.
