Improvement of the atmospheric environment in urban planning is an important issue to implement the sustainable development of cities. In this paper, in order to meet the demand of planning office to compare and assess quantitatively of the designs in multi-scale, based on geographical information system (GIS) data with high resolution, a multi-scale numerical modeling system for the atmospheric environment impact of urban planning is set up, and the multi-scale assessment index system is established, which compose the technology system of multi-scale assessment of the impact on the atmospheric environment by urban planning. In urban planning (urban development of Beijing) and optimizing layouts of Olympic Green, it has been applied to quantitatively evaluating the impact on atmospheric environment by urban planning before construction, which offers scientific foundation to optimize the whole and local urban layout.

The comprehensive impact of atmospheric dry deposition and wet deposition and the pollution sources of farmlands, mining areas, and towns along the Baihe River on the water quality of Miyun reservoir is investigated from the angle of the complex sources of air-soil-water pollution processes, in the context of the 1990-2001 precipitation chemical data at Shangdianzi station-a WMO regional background air pollution monitoring station 15 km far from the Miyun reservoir, in conjunction with the atmospheric dry deposition and wet deposition data of the 2002 -2003 Beijing City Air Pollution Observation Field Experiment (BECAPEX). Analysis results suggest that the major ions in precipitation in the Miyun reservoir region in this period were SO 42-, NO 3-, NH4+ and Ca2+; wet acid deposition quantity of Miyun reservoir in the summer half year (April to September) was greater than the quantity in the winter half year (October to March), and the annual wet acid deposition in the reservoir exhibited a rising trend with the mean 1038.45 t, the maximum 1766.31 t occurred in 1996, and the minimum 604.02 t in 1994; the long-term averaged pH of atmospheric precipitation in the Miyun reservoir region was 5.20, i.e. weakly acidic, and the interannual variation of pH values displayed a falling trend. pH values of water body at various depths in the Miyun reservoir were all greater than 7.0, but they exhibited vertical and horizontal nonhomogeneity, and at the same region pH decreased vertically with depth; the 2002 and 2003 annual dustfalls in the Miyun reservoir were 13513.08 t and 3577.64 t, respectively, and the spring dustfall was the number one in a year, accounting for the 61.91% and 44.56% of the annual totals of 2002 and 2003, respectively. Because the atmospheric dry deposition and wet depositions contain multiple types heavy metal elements and harmful elements, they to some extent exacerbated the eutrophication, acidification and potential heavy metal pollution of the reservoi

[Objective] The aim was to analyze the process and reason of the extreme heavy rainfall on June 15,2011 in Cold Lake in Qinghai.[Method] The weather,physical field and satellite of one extreme heavy rain in the cold lake in Qinghai were expounded.[Result] The formation of the loop 'crooked neck' of high pressure,which on the one hand posed a typical situation in the circulation of heavy precipitation in Qinghai,and on the other hand,formed the southwest,southeast of the two water vapor transport in air,in addition to the small groove from the trough of Lake Balk hash and the split vortex plateau,resulted into the extreme heavy rainfall in Cold *** presence of thermal low pressure 700 hPa was conducive to the accumulation of low energy and low-level moisture transport from the Qinghai region to the south of Qaidam Basin.[Conclusion] The resulting process was mainly due to heavy rain in the lower troposphere convergence,high-level divergence,high humidity areas and a strong vertical upward motion.

The material discussed in this report was collected at 23 stations in the north of the continental shelf of the East china Sea from October 4 to November 5, 1977 with a Juday phytoplankton net (diameter 37 cm, No. 20 gauze) which was towed from the bottom to the surface of the sea. The Results anlayzed show that the species composition and distributon of dinoflagellates in this region bear a close realtionship to the water mass and the sea currents. Based on the temperature ranges in which different species of dinoflagellates flourish, they may be divided into three groups: cold-water species, warm-temperate species and warm-water species. The number of the last group is more than 70% of the total.

基于线粒体DNA控制区序列比较分析了斑尾复虾虎鱼丹东和天津群体的遗传多样性及其遗传结构现状。研究结果显示,在长度为478 bp的线粒体DNA控制区序列上,两群体间存在一定程度的差异。丹东群体的单倍型多样度、核苷酸多样度以及两两序列比较的平均碱基差异数分别为(0.006 3±0.003 8),(0.889 5±0.050 8)和(3.000 0±1.634 3),均大于天津群体。基于控制区单倍型序列构建的邻接关系树可以看出,两群体个体相互混杂,没有明显的分支与之相对应。两个群体之间遗传分化指数FST值为0.239 5(P=0.000),表明两群体之间存在较大的遗传分化,并且确切P检验的结果表明两群体不存在随机交配现象。核苷酸不配对分布呈单峰类型,Fu’sFs和Tajima’D中性检验的结果也提示斑尾复虾虎鱼经历过近期群体扩张事件。基于核苷酸不配对分布的峰值τ计算得到斑尾复虾虎鱼发生群体扩张事件的时间在52 400～104 900年前。
