2005年12月和2006年6月对苏州平原河网区57个浅水湖泊的浮游植物群落进行了调查，共检出浮游植物8门62属73种，浮游植物主要由绿藻、硅藻和蓝藻组成。

During early middle Jurassic period, Quemocuo formation in NQB was offshore lake deposition with marine feature, in SQB was shelf deposition, which indicted that an intense rifting and sea level rising with more large range, and consequently, eroding area was shrunk and deposition area was expanded.4. According to the result of stratigraphic surface features, division and correlation, and the paleographic characteristic, Qiangtang Basin during late Triassic -early middle Jurassic period could be divided into two basin developing stages with difficult tectonic nature, remnent epicontinental basin stage in Carian -early Norian of late Triassic and rifting basin stage in middle Norian of late Triassic - early middle Jurassic period respectively.

雀莫错组在羌北盆地为近海湖泊沉积，更具海相色彩：南羌塘主要为外陆棚沉积，反映羌塘盆地再次发生较强烈的裂陷作用和较大幅度的海平面上升，形成陆源剥蚀区缩小，沉积覆盖面增大的古地理面貌。4、根据地层界面特征、地层划分与对比结果和岩相古地理演化特征可将晚三叠世—中侏罗世早期羌塘盆地划分为两个不同构造性质的盆地发展时期，分别为晚三叠世卡尼期—若利早期的残留内陆表海沉积盆地发展与消亡时期和晚三叠世若利期中晚期—中侏罗世早期的裂陷盆地的形成与发展时期。

At last. on the basis of comprehensive studies of the glacial, lake, periglacial phenomena .palaeosols and paleontology in the research areas. the late stadial of the Last Glaciation can be divided into three periods: the early phase, 25000-20000a. B. P.. with the cold and wet climatic conditions; the middle phase, the full of last glacial maximum. 20000-16000a. B. P., with the cold and dry climatic conditions; and the late phase, 16000 10000a. B.P., with the warm and dry climatic conditions besides the Younger Dryas event.

最后，根据对研究区的冰川、湖泊、冰缘现象、古土壤和古生物等在末次盛冰期中的发育、演化状况的综合分析，把末次盛冰期大致划分为三个阶段：早期，25000-20000a.B.P。，气候条件主要表现为冷湿；中期，20000-16000a.B.P。，气候条件主要表现为冷干；晚期16000-10000a.B.P，气候条件主要表现为温干，但Younger Dryas事件也有反映。

Carry research of geochemistry of sample of core of cliff of bore of 6 Ju ZK24401, think old village paragraph it is half drought - the laky deposit of brim of the basin below condition of half damp climate is formed, area of source of content of deposit object distance is closer, process of its deposit evolution and content source area have consistency.

通过六苴ZK24401钻孔岩芯样品地球化学探究，认为大村段是半干旱-半潮湿气候条件下盆地边缘的湖泊沉积形成，沉积物距物源区较近，其沉积演化过程和物源区具有一致性。

On Beijing program domain, 4 annulus road passes through or border east town of stage of garden area, abundant, Haidian presses down high-tech of stage of development of technology of economy of area of outskirt electron city, spin, chemical industry area, Yi Zhuang, Na Yuan, abundant, ZhongGuanCun, Ya Yun Cun, and with 12 road of 7 high speed, railroad, tens of urban artery, 3 0 many river is laky intersect.

在北京市规划版图上，四环路穿越或毗邻东郊电子城、纺织区、化工区、亦庄经济技术开发区、南苑、丰台高科技园区、丰台镇、海淀镇、中关村、亚运村，并与七条高速路、12条铁路、数十条城市干线、3 0多条河流湖泊相交。

Based on grain size analysis and core observation, main deposition systems have been recognized, including incised valley infilling system, lacustrine system, sublacustrine fan system and delta system. Among them, valley infilling system occurs in later lowstand system tract distributed in northern area, and sublacustrine fan system lies in southern area in early lowstand system tract.

通过粒度分析和岩心观察，认为中油组主要沉积体系包括侵蚀沟谷充填沉积体系、湖泊沉积体系、湖底扇沉积体系、三角洲沉积体系，其中低位侵蚀沟谷主要分布在研究区北部，主要发育在低位体系域晚期，湖底扇主要分布在研究区南部阿克亚苏地区，主要为低位体系域早期沉积。

Due to food pressure, grain product in the western Jilin Province will be enhanced in the near future. Farmland areas in the area will be decreased slowly in the near future, but with the technique development of irrigation establishment, paddy areas and utilization amount of fertilizer and pesticides will be increased rapidly. So, the NPS pollution from farmland will be more serious. The main lakes in the areas such as Moon Lake and Qagan Lake have been polluted by N and P, and the content of salt in the Nenjiang River has been increasing since last 30 years. All of these show that the negative effects of NPS pollution in the area have been serious and should not be neglected by the scientific research and corresponding government management. To deal with the contradiction of agriculture development and water pollution, the trend of increasing paddy area and using amount of fertilizer, pesticide and herbcide in the western Jilin Province should be controlled. Also, the drainage of return flow from paddy should be controlled and return flow should be disposed with ecotechniques by use of the large areas of lakes and mires in the area. Through these measures, the quality of surface water could be protected and the degeneration of ecoenvironment in the area could be contained.

我国由于粮食压力，未来吉林西部的粮食生产还将进一步加强，随着种植业结构的调整，垦殖率会略有下降，但随灌溉设施的建设与完善，水田面积将进一步扩大，化肥、农药的用量还将快速增加，农业活动引起的非点源污染将更加突出，而研究区的主要湖泊月亮湖、查干湖目前已达中等富营氧化水平，嫩江水质的咸化趋势明显，因此农田非点源污染物的流失及其内流区外流化面积的增加对地表水体富营养化、咸化的作用愈来愈明显，农田非点源对地表水水质的影响已不容忽视，应引起社会的关注，为协调农业发展与水污染这一矛盾，吉林西部应遏制化肥、农药施用量增长过快和水田过度开发的势头，控制洗盐回归水的排放量，利用区内广泛分布的大量泡沼对农田径流和回归水进行生态处理，既保护了地表水的水质，又有利于生态环境的改善。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
