| 1 | Interactive effect of dissolved organic matter and phenanthrene on soil enzymatic activities显示文摘The investigation of dissolved organic matter(DOM) on urease,catalase and polyphenol oxidase activity in a phenanthrene(Phe)contaminated soil was conducted under laboratory incubation conditions.Values of soil enzymatic activity depended mainly on incubation time.In the initial 16 days,urease activity increased,and was followed by a decrease.In the initial 8 days,catalase activity decreased and then increased.Variation of polyphenol oxidase activity was just the reverse of catalase activity.After 30 days of incubation,no pronounced difference among treatments with Phe,Phe and DOM,and control were detected in urease,catalase and polyphenol oxidase activity.Phe might inhibit urease and catalase,and stimulate polyphenol oxidase.DOM could improve inhibition of Phe in soil urease and catalase activity during the initial period of applying DOM.Nevertheless,DOM had no significant effect on polyphenol oxidase activity in the Phe contaminated soil.There was a negative correlation between catalase and polyphenol oxidase(r =-0.761***),and catalase and urease(r =-0.554**).Additionally,a positive correlation between polyphenol oxidase and urease was also detected(r = 0.701***).It is implied that the formed DOM after application of organic wastes into soils may counteract the inhibition of polycyclic aromatic hydrocarbons in soil enzyme activities. | Xinhua Zhan,Wenzhu Wu,Lixiang Zhou,Jianru Liang,Tinghui Jiang College of Resources and Environmental Sciences,Nanjing Agricultural University,Nanjing 210095,China.Greenstar Plant Products Inc.,9430 198 St,Langley,BC,Canada V1M3C8. | 2010 | Journal of Environmental Sciences2010，22，4： | 10 |
| 2 | Mixed-layer water oscillations in tropical Pacific for ENSO cycle显示文摘The main modes of interannal variabilities of thermocline and sea surface wind stress in the tropical Pacific and their interactions are investigated,which show the following results.(1) The thermocline anomalies in the tropical Pacific have a zonal dipole pattern with 160°W as its axis and a meridional seesaw pattern with 6-8°N as its transverse axis.The meridional oscillation has a phase lag of about 90° to the zonal oscillation,both oscillations get together to form the El Ni?o/La Ni?a cycle,which be-haves as a mixed layer water oscillates anticlockwise within the tropical Pacific basin between equator and 12°N.(2) There are two main patterns of wind stress anomalies in the tropical Pacific,of which the first component caused by trade wind anomaly is characterized by the zonal wind stress anomalies and its corresponding divergences field in the equatorial Pacific,and the abnormal cross-equatorial flow wind stress and its corresponding divergence field,which has a sign opposite to that of the equatorial region,in the off-equator of the tropical North Pacific,and the second component represents the wind stress anomalies and corresponding divergences caused by the ITCZ anomaly.(3) The trade winds anomaly plays a decisive role in the strength and phase transition of the ENSO cycle,which results in the sea level tilting,provides an initial potential energy to the mixed layer water oscillation,and causes the opposite thermocline displacement between the west side and east side of the equator and also between the equator and 12°N of the North Pacific basin,therefore determines the amplitude and route for ENSO cycle.The ITCZ anomaly has some effects on the phase transition.(4) The thermal anomaly of the tropical western Pacific causes the wind stress anomaly and extends eastward along the equator accompanied with the mixed layer water oscillation in the equatorial Pacific,which causes the trade winds anomaly and produces the anomalous wind stress and the corresponding divergence in favor to conduce the oscillation,which in turn intensifies the oscillation.The coupled system of ocean-atmo-sphere interactions and the inertia gravity of the mixed layer water oscillation provide together a phase-switching mechanism and interannual memory for the ENSO cycle.In conclusion,the ENSO cycle essentially is an inertial oscillation of the mixed layer water induced by both the trade winds anomaly and the coupled ocean-atmosphere interaction in the tropical Pacific basin between the equator and 12°N.When the force produced by the coupled ocean-atmosphere interaction is larger than or equal to the resistance caused by the mixed layer water oscillation,the oscillation will be stronger or maintain as it is,while when the force is less than the resistance,the oscillation will be weaker,even break. | ZHAO YongPing1,CHEN YongLi1,WANG Fan1 & WU AiMing2 1 Institute of Oceanology,Chinese Academy of Sciences,Qingdao 266071,China 2 Department of Earth & Ocean Sciences,University of British Columbia,Vancouver,BC,V6T 1Z4,Canada | 2007 | Science China Earth Sciences2007，50，12： | 7 |
