A review of river management history in various countries is used in this thesis to discuss the future development trends of river management and the relationship between river health and river management.Based on the characterization and assessment of river health, Five components of stream condition are presented in this thesis to characterize river health: water quality, aquatic life, physical form, hydrology and streamside zone. It is obtained by comparing the methods and criteria that have been developed by others and reviewing the river assessment practices in various countries. Accounting for the features of urbanization region in plain river network, an indicator system for river health assessment which provides scores for 5 subindices and 17 indicators is established. With almost 200 stream reaches in Shanghai as objective of study and Liwa stream and Zhangjiabang Creek as case study, the application of river health assessment in the planning, baseline survey and post-project appraisal of river management is explored by collecting historical literature and field monitoring. Consequently, some suggestions to improve river management effectiveness are presented from the angle of river health.

本文回顾河流管理漫长历程并指出当前国际发展趋势，进而辨析河流健康状况与河流管理的关系；以河流健康状况的表征和评价为核心，通过对国外RIVPACS、AUSRIVAS、IBI、RCE、ISC等河流健康状况评价方法的分析和比较，以及对美国、英国、澳大利亚、南非等国家河流健康状况评价实践的总结，尝试从理化参数、生物指标、形态结构、水文特征、河岸带状况5个方面全面表征河流健康状况；结合中国东部平原河网地区自身特点，通过评价原则、评价指标、评价标准、评价权重确定等步骤，初步构建了包含河流水文、河流形态、河岸带状况、河流水质以及河流生物5个一级指标(共17个指标)的河流健康状况评价指标体系；在此基础上，采用资料收集与现场实测相结合的方法，以上海近200条中心河道为研究对象，以丽娃河和张家浜为典型案例，分别就河流健康状况在河流管理规划、现状评估以及后评估中的应用进行实证研究，并尝试探讨如何从这三个阶段利用河流健康状况评估改进河流管理的对策。

Presently narcissus stopped to drink from alittle stream.kneeling down on the bank,he saw alovely face in the clear water.你好s heart gave abeat.he smiled and was smiled back to.t你好nking that it must be amaiden in love with 你好m,he bent down to kiss her.and her lips also drew near 你好s.but as soon ashe touched the clear surface the lovely face disappeared.the angry youth was now desperate.never had he been looked downupon like that before.day and night,he stayed at the stream without drinking and eating.before long he died,never suspecting that 你好s maiden was just 你好s own image in the stream.the gods took pity on the fair dead body and turned it into aflower bearing 你好s name.

不久，那西塞斯降临一条小溪边饮水当他跪在岸边时，他发现清亮的溪水中有一张非常可爱的面庞他非常冲动，并对于着水中的人微笑，水中人也给了他一个微笑他认为，一定是一位女神爱上了他于是，他就蹲下去吻她，她的嘴唇也向他靠拢但是，当他的嘴唇一接触清亮的溪水，水中那张可爱的脸就消失了这位恼怒的小伙子人此时变得绝望了，他从未被人云云鄙视过改日夜呆在溪边，不吃不喝，不久就死了他从未思疑过水中的女孩只是自己的影子而已众神非常怜悯他那优美的躯体，把他变成了一朵重名的花

The invention discloses a software security ensuring method based on program internal behavior monitoring which comprises,(1) the language code analyzer analyzing the program control stream, adding description control stream transformation code, adding assisting protection function for the program, then compiling into performable program,(2) transferring the treated program to a program charging device, determining whether the current program has a protection function,(3) submitting operation system the protection information of the progress and setting the program progress protection sign to TURE,(4) the operation system kernel determining the progress protection sign, go to step 7 if the result is FALSE,(5) the operation system kernel examining the progress control stream conversion consistency,(6) continuing the progress,(7) finishing.

本发明公开了一种基于程序内部行为监控的软件安全保障的方法，其步骤是：1。语言代码分析器分析程序的控制流，并添加描述控制流转换代码，添加程序的协助保护功能，然后编译成可执行程序；2。处理过的程序递交给程序加载器，判断当前程序是否具有保护功能，如果有则加载适当的运行环境，否则转到4；3。向操作系统递交该进程的保护信息并设置该程序进程的保护标志为真；4。操作系统内核一旦获得控制权利，则判断进程的保护标志，如果为假转到7；5。操作系统内核检查该进程控制流转换的一致性，如果不一致，发出安全警告，并杀死进程，转到7；6。继续运行进程；7。结束。本发明的显著优点是提高了安全保障方法的精确性和通用性。

Integrated analysis of 7 times heavy rain in Yunnan from July 19 to August 2 based on actual observation weather datum and satellite cloud atlas and Doppler radar image. The results show that: high-low southwest jet stream is important effect system. The maintenance of southwest jet stream provides water vapor, momentum, fast transfer of unstable energy for the lasting heavy rain. The further configuration of plateau shear line and southwest jet stream is necessarily condition about 7 times heavy rain. The lasting heavy rain appeared on big value region of 500hPa vapour flux and vapour flux divergence. The shear cloud band and subtropical high cloud band crossed and confluenced in Yunnan on the satellite cloud atlas. The maintenance and intensification of shear cloud hand and periphery cloud band of subtropical high correspond quite well to heavy rain falling region and cloud band distribution.

应用实测气象资料，结合卫星云图与多普勒雷达图像分析，对2007年7月19日到8月2日云南少有的7次强降水过程进行综合分析，结果表明：高低空的西南急流是重要的影响系统，西南急流的维持为持续性强降水过程提供了水汽、动量和不稳定能量的快速传递，高原切变线与西南急流的有利配置，是7次持续性强降水过程必不可少的条件；持续性强降水出现在500hPa水汽通量大值区和水汽通量散度辐合区；卫星云图上切变云带和副高外围云带在云南汇合，切变云带和副高外围云带维持、加强的过程与强降水落区的时空分布对应较好。
