Its rule of change was obtained. On the basis of other studies, the flocculation kinetics and flocs structure was studied. By making some assumptions, collision frequency were presented. Then the the flocculation kinetics model was established through population balance equation. Comparison of experimental data and modeling results indicate that there are the same trend between the two. So the model can predict flocs number and size during flocculation of Yellow River's loess particles without using empirical parameters. The TEM and SEM were used to obsever flocs in the study of floc structure. The flocculation was divided as flocculi, floc and floc aggregate. The flocs structure model was established by assumption that particles position in floc accords with tetrahedron. The fractal dimension of model and experimental flocs was found to be coincident. So the model can reflect the structure of flocs formed in flocculation of Yellow River's loess particles by macromolecule flocculant at a certain extent.

最后，本文还对絮凝动力学和絮体结构进行了研究，在前人研究的基础上，针对高分子絮凝黄河泥沙，对絮凝过程作了一些符合试验条件的假设，建立了颗粒碰撞频率表达式，应用了颗粒数量平衡方程，从而建立了絮凝过程的动力学生长模型，模型计算结果与试验数据对比表明，二者趋势一致，在没有使用经验参数的情况下基本上能够描述黄河泥沙絮凝过程中絮体数量和尺寸分布的变化过程；对絮体结构的研究中，应用扫描电子显微镜和透射电子显微镜对絮体进行了观察，将絮体分为絮粒、絮团和絮网三个不同的生长阶段，通过假设颗粒结合位置符合正四面体，建立了絮体结构模型，计算得到的模型絮体分形维数基本与试验中的实际絮体相符，在一定程度上能眵反映高分子絮凝黄河泥沙生成的絮体结构。

The project of TEDA River is an active attempt in salt land area environment rebuilding. There are some innovation in the use of water source, the recovery of salt land green system and the special art wetland scenery.On the other hand, the most important thing is the economic assessment of one hundred and fourteen acre. At last, the leader of TEDA agrees with our conception for building a large river and wetland forest park.

It is well known that Huang-huai-hai Plain flourished around Han and Tang dynasties, not only boasted of the highly developed agricultural economy, handicraft industry and cultural education, but also of the population quality and proportion. while the physiognomy of the Plain has changed greatly since Song and Yuan dynasties due to the frequent deluge and the river course change of Yellow River, which caused the changes of the trace elements amount in the plain\'s soil, especially the decrease of virtual zinc which caused the cultural developing process to stagnate gradually after Song and Yuan dynasties. Trace elements like a invisible hand worked uniquely on cultural developing process.3The geographical environment and the morbid population of Lin Xiang Kingdom in Sun-Wu Kingdom Period.

二地理环境下的土壤微量元素的变化状况与历史时期黄淮海平原文明进程的关系：众所周知，汉唐时期是黄淮海平原地区文明程度最高的时期，不仅农业经济、手工业经济和文化教育高度发展，而且人口素质和人口比重也是占据极为重要地位；但是，由于黄河的频繁泛滥和改道，不仅造成了黄淮海平原地貌的巨大变化，而且也引发了黄淮海平原土壤微量元素的变化，以致有效锌严重缺乏，从而使得宋元以后的黄淮海平原的文明进程逐渐停滞下来；而在此过程中，土壤微量元素锌像一支看不见的手在起着独特的作用。

During the four years study on the project, we develop a dynamical forecast model that describing the subtropical ridge surface. A new theory on the role of the land-sea thermal difference on the formation of the Subtropical High is advanced. It is concluded that in the summer subtropics over each continent and its adjacent ocean LO, SE, CO, and a double-dominant heating from west to east compose a LOSECOD heating quadruplet. The influence of the Eurasia continent on SH varies according to the seasonal variation. From the ideal numerical simulation it is shown the important role of the Eaiuan continent and the huge topography on the mechanism of formation and mantanence of the SH during the summer. It is verified by the numerical simulation that the extension of the subtropical continent into the tropics greatly enhances the " East Asian monsoon". Through the Rossby energy dissipation theory it is verified that the deep latent convective heating induces the onset of the South China Sea monsoon over the Bay of Bengal. The relationship and mechanism between the precipitaiton over the East Asia and the Subtropicla high is illustrated by the data. It is also found the close phase lock between the east-west shift of the SH and the disturbence of the east wind belt over the tropical troposphere. The interaction between the structure and activity feature of the SH and the Meiyu over the Yangtze-Huaihe river valley is revealed from the data. The numerical simulation verified the impact of the different SH pattern on the path of the typhoon.
