本文采用常规鉴定方法与雄性外生殖器解剖相结合，辅以扫描电镜观察，对收藏于新疆大学生命科学与技术学院昆虫室20年来积累的标本及三年在校期间系统地采集于全疆各地的拟步甲类标本进行了整理与鉴定，结合野外考察及重要类群的生物学研究，研究其区系成份，并对其区系特征及地理分布状况进行了系统的分析，主要研究成果如下：1）初步查明新疆拟步甲科昆虫共计266种，分隶于23族72属，其中35种为中国新记录种，3种为拟步甲类新种，作新种记述，并附图片；在研究过程中初步探讨了拟步甲的中文命名问题； 2）新疆拟步甲种类繁多，其区系成分分析显示，除12种为广布种以外，共有6种区系成分，其中中亚细亚种为最多，有87种，占已种的32.7﹪；其次依次为中央亚细亚种和特有种，分别为81种和65种，各占已知种类的30.5﹪和24.4﹪；泛古北种12种，占4.5﹪；欧洲西伯利亚种7种，占2.6﹪；欧洲中亚种最少，仅有2种，占0.75﹪，并根据新疆拟步甲科昆虫区系成分分析了其起源问题； 3）新疆拟步甲科昆虫的地理分布表明，分布于准噶尔盆地的种类最为丰富，计161种，占新疆已知种的60.5﹪；其次是塔里木盆地92种，占已知种的34.6﹪；东疆诸盆地63种，占23.7﹪；伊犁谷地56种，占21.1﹪；在三大山系中，天山山系的拟步甲种类最多，为54种，占20.3﹪；阿尔泰山山系28种，占10.5﹪；昆仑山山系13种，占4.9﹪。

Based on above studies, some main conclusions were obtained as follows : 1 the diatoms forming mats in low latitude west pacific is"shade flora"diatom Ethmodiscus rex Hendey; 2 the sites found diatom mats are zone distributed, the direction is NW-SE and most distribute in the deep water area with flat seafloor, between 17°N～20°N and the water depth 4837-6150 m below Carbonate Compensation Depth (CCD 3) AMS 14C dates show that the sediments rich in diatom mats occurred during 16.0 ~ 28.6 ka B.P., which means the bloom mainly occurred in last glacial maximum, while there are not diatom mats deposits in other layers; 4 A total of 101 diatom taxa belonging to 40 genera had been identified from the 155 samples in the two cores WPD 03 and WPD 12, and the relative percentage of Thalassionema frauenfeldii are the highest, Thalassionema nitzschioides、Azpeitia nodulifera、Hemidiscus cuneiformis、Nitzschia marina take the second place.

14C年期间，即&勃发&发生于末次冰期最盛期；4在WPD 03和WPD 12两个岩芯共155个样品中共鉴定硅藻40属101种，且Thalassionema frauenfeldii的相对百分含量最高，Thalassionema nitzschioides、Azpeitia nodulifera、Nitzschia marina、Hemidiscus cuneiformis等次之，这五种硅藻占整个硅藻物种相对百分含量的85%左右，说明在该海域表层水体硅藻席沉积过程中，这五种硅藻最容易与成席硅藻在同时期的环境中生存，形成勃发；5MIS3期的晚期，该区域表层海水盐度降低，这有助于该区水体的成层化，从而使&树荫种&硅藻开始勃发，导致&秋季倾泻&；6末次冰期由于南极中层水北扩，南大洋中层水将富含硅酸盐的海水带入了研究区，即南大洋的&硅溢漏&作用，使该区域硅藻得以勃发，同时，铁输入的增多，可能也是造成硅藻勃发的主要原因之一。

Based on the trophodynamics in marine ecological system and the primary productivity data from the fishing grounds of east Fujian during the marine investigation in Taiwan Strait, the concentration of organic carbon of phytoplankton and 52 species of main economic fishes were determined, and the nutritive level of the fishes and ecological efficiency in the fishing ground were calculated. The ecological carrying capacity of fish resources was 630800 tons using Cushing model and dynamics model.

闽东渔场位于26000'一27010'N、1 19050'一125000'E，北邻浙江温台渔场，南接台湾海峡，属亚热带海第2期林法玲：闽东渔场鱼类资源生态容量和最大可持续开发量域，鱼类资源丰富，系我国南方海域重要渔场之一。20世纪80年代以来，闽东渔场鱼类资源呈现衰退现象，有关鱼类资源生态容量和可持续开发量是渔业生产和管理部门所关注的问题。

The difference of bulk density of coastal soils took an effect on infiltration rate and diffuse rate. The infiltration rate and diffuse rate of coastal soils which bulk density was small were big. The water transmitting experiment of coastal soils showed that the saturated conductivity of different layers in soil profile were great, and the saturated conductivity of undisturbed soil was highly higher than that of disturbed soil. The saturated conductivity of coastal soils embanked earlier was lower than that of coastal soils embanked later. Under different water content, the unsaturated conductivity of coastal soils had a great change and the bulk density had an effect on unsaturated conductivity. The soil with a low bulk density had a high unsaturated conductivity. Chlorine ion moved in coastal soil was an inert ion. The distribution of CU in soil was definite and repeated, which is no relation with the time and velocity of infiltration. The concentration of infiltration solution and the texture of coastal soils had no apparent effect on solute movement synthetic dispersion coefficient, while bulk density took an apparent effect on solute movement synthetic dispersion coefficient. Synthetic dispersion coefficient of coastal soils increased as bulk density decreased.
