With theoretical introduction and example analysis, the relationship between the living beings and it's environment could be elucidated at the level of individual, population, biocoenosis, ecosystem, and biosphere, respectively, aiming at making the students have the capability to grasp the fundamental knowledge system of ecology and ecological ideology, and improving the understanding of the environment problem.

本课程主要从个体，种群，群落，生态系统和生物圈等不同层次上分析生物与环境之间的关系方式，通过理论推介，案例剖析，使学生掌握生态学的基本知识体系和思想方法，形成宏观的生态思维，提高对当前资源和环境问题的认识能力和把握水平。

When formed, the internal tides travel away from its generation area. Wherever it reaches, it makes the sea water there mixing heavily and the objects exchange up and down, which influences the distribution of ocean biocoenosis and the action and the safety of submarine and other objects in the ocean. Therefore, it's very important to study internal tides both in application and in theory.

内潮向浅海和深海传播，所到之处，海水会发生强烈的垂直混合，使上下层的物质发生交换，从而影响到海洋中生物群种的分布以及水中工程设施、潜艇等的功能及安全，所以，对内潮的研究有着重要的理论和实际意义。

Internal tides (internal waves of tidal frequency) are generated, usually in the connecting area between shelf and slope, by the tide-topography interactions and they have many effects on biocoenosis and objects in the ocean.

海洋中的陆架坡折区是地形变化剧烈的区域之一，当表面潮与这里的地形发生相互作用时，在该区域层化的海水内部引起强烈的扰动从而形成内潮。

The constituent characters of the POPs,the toxicology effects for the biocoenosis,the pollution sources,the environmental analysis,the environmental behaviors, food chain transition and the regional and the global pollution transition are expounded in the paper.

本文综述了持久性有机污染物的成分特性、对生物群的毒理效应、环境污染源、环境分析、环境行为、食物链传播、地区性或全球性的污染传输等问题。

As temperature increased from 40 to 70℃, ferric reduction capacity of microorganism biocoenosis from Jilin, Tianjin and Hunan paddy soil were restrained to a certain extent. Adding AQDS could increase ferric reduction rate of microorganisms biocoenosis from Jilin, Tianjin and Sichuan paddy soil significantly. In axenic culture treatment of 6 kinds of bacterial strain experiments from Sichuan and Jiangxi paddy soil, a bacterial strain was suitable to 50℃.

于40~70℃升温处理后，来源于吉林、天津和湖南水稻土微生物群落的铁还原能力受到一定程度抑制；添加AQDS可显著增加来源于吉林、天津和四川水稻土的3种微生物群落的铁还原反应速率；在6株铁还原菌的纯培养试验中发现了1株更适于在50℃下生长的菌株。

After comparison of 30 and 50℃ treatments, AQDS were added into 3 kinds of microorganism biocoenosis from Jiling, Tianjin and Sichuan paddy soil, and it showed that AQDS could accelerate the reduction of Fe 10%-288%, meanwhile, temperature could accelerate the reduction of Fe 6%-17%. In axenic culture treatment of 6 kinds of bacterial strains from Sichuan and Jiangxi paddy soil, the maximum accumulation amount of Fe reduction rate was constant, the maximum reaction rate and ferric reduction rate of ferric strain JX-a08 all increased as temperature rose, which showed that bacterial strain JX-a08 were suitable to 50℃.

在30和50℃培养温度下，来源于吉林、天津和四川的3种水稻土微生物群落添加AQDS可使Fe还原的反应速率常数增加10%~288%，而温度变化的增加幅度仅为6%~17%；对分离自四川和江西水稻土中的6株铁还原菌的纯培养试验发现，菌株JX-a08的Fe最大累积量、还原速率常数、最大反应速率及铁还原率均随培养温度的升高明显增加，表明菌株JX-a08更适于在50℃下生长。

5 kinds of paddy soil treatments were studied, then each microorganism biocoenosis was extracted or bacterial strain was dissociated. Artificial synthesis ferric oxide was considered only electron acceptor, which inoculated soil leaching liquor or bacterial strain with reduction function in mineral salt culture system under anaerobic constant temperature condition. After different temperature treatments towards leaching liquor, temperature was controlled and AQDS added into culture system in order to discuss the effect of temperature and AQDS on ferric oxide microorganism reduction process.

采用5种水稻土为供试材料，分别提取微生物群落或分离铁还原菌株；以人工合成氧化铁作为惟－电子受体，在无机盐培养体系中接种土壤浸提液或具有铁还原功能的菌株，厌氧恒温培养；通过对接种液的不同温度处理(40， 50， 60， 70℃)、对培养温度的控制（30和50℃）以及向体系中添加AQDS，探讨温度及AQDS对氧化铁微生物还原过程的影响。
