以生物的活动力来看，选择栖地现有青苔、岩石、木头、土壤及外来的混凝土作为水岸边坡基质，量测阿里山山椒鱼的攀爬能力。

Soil samples were collected from different ecological conditions. More than 70 Streptomyces hygroscopicus strains were isolated from the soil samples. Fermentation centrifugal supernatant of the strains were used as biocontrol agents to bioassay the seedling of rice and barnyard grass and rice pathogens of sheath blightand bakanae. Three strains showed good effects of inhibitingbarnyard grass seedling, the another three strains well inhibited the growth of rice pathogenic fungi.

从国内外不同生态条件下采集的土壤标本中分离到70多个吸水链霉菌，用其发酵离心上清液对水稻、稗草秧苗和稻纹枯病菌、恶苗病菌进行生物测定，结果有3个菌株对稗草根的生长具有较好的抑效果；有3个菌株对水稻病原菌有很好的抑制生长作用。

The results show that, the nitrate-N concentration in groundwater in the reed area was 0.2~0.8mg/L and significantly lower than that in surrounding wells (more than 20mg/L), and the reed wetland can remove nitrate pollution in shallow groundwater. The distribution of denitrifying bacteria showed obvious rhizosphere effect, and the higher biodenitrification in natural reed wetland was related to the distribution of denitrifying bacteria. There was a negative relationship between the nitrate-N concentration and the number of denitrifying bacteria in groundwater.

结果表明：芦苇区浅层地下水中硝酸盐氮仅为0.2~0.8mg/L，远低于湿地周围井水中硝酸盐氮质量浓度（大于20mg/L），芦苇湿地能够去除浅层地下水中硝酸盐污染；反硝化细菌在土壤中的分布呈现明显的根际效应；野生芦苇湿地较强的生物脱氮作用与反硝化细菌分布有关，地下水中硝酸盐氮含量与反硝化细菌分布呈负相关。

This study will provide the references for bioremediation of contaminated soil by DDT.

结论］该研究结果为DDT污染土壤的生物修复提供依据。

It is not only connected with carbondioxide output of bio-body and also with maintenance in soil carbon bank. It is a fundamental basis of function and process and takes a guiding role in terrestrial vegetation carbon bank.

森林生物量不仅联系着生物CO〓的排放量，而且维持着土壤碳库的贮存，是生态系统功能、过程的重要基础，它在陆地植被的碳库中起着主导作用。

BioGroup membership is open to environmental engineers, soil scientists, microbiologists, environmental chemists, and all who wish to contribute to this important topic.

该生物组面向环境工程师、土壤科学家、微生物学家、环境化学家和所有希望在该领域有所贡献的人。

The mobile fractions of heavy metals, namely EXCH, CAR,FeMnOX, and OMB, also influenced their leaching concentrations. Especially the EXCH andFeMnOX of Cu, Zn and Pb were negtively correlated with their contents in soil solution.The bioleaching with Thiobacillus ferrooxidans was used for decreasing concentrations of heavy metals in sewage sludge.

土壤中EXCH、CAR、FeMnOX及OMB形态重金属的变化与其溶出量显著相关，特别是以EXCH与FeMnOX形态存在的Cu、Zn、Pb含量的变化均与其溶出量呈显著负相关关系。5、利用以FeSO_4为底物的氧化亚铁硫杆菌对污泥进行生物沥滤去除重金属。
