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。

The paper sees Horton code as a primary characteristic value and generalizing condition of the river network, and selects, simplifies and generalizes river based on scale of before and after generalization,, The main contents of paper include:(1)Reviews generalization concept, arithmetic operators, methods, influence factor and frame of map generalization and design, analyze core theory of feature —oriented map generalization, discuss the main context and applicable method of river feature generalization(2) Summarizes natural form and spatial configuration characteristic of the river network, and describe the river network using digraph Paper mostly researches tree —like river, identifies the direction of river based on the angle of the main and secondary reach, and identifies the main river based on most length and predominant continuation of the flow direction along the major channel , then receives the grade of river by recursion and structuralize river network, builds hiberarchy rank system of river based on Horton coding(3)Designs the model of river network based on Horton code, and organizes the data of node, branch and river.

本论文把Horton编码作为水系网的一个主要特征值并以此作为综合条件，并根据综合前后的比例尺对水系网进行选取、化简和概括。论文的主要工作包括：(1)总结地图综合的概念、算子分解、实现方法、主要影响因素和总体设计框架，分析面向地理特征的制图综合的核心理论支撑，在此基础上讨论水系专题要素综合的主要内容和综合适用的方法。(2)总结水系网的自然形态和空间结构特征，用图论对水系网进行描述。以树状水系作为主要研究对象，依据树状水系的主支流交汇关系确定水系流向，依据水系中主流的长度最长和主流保持原有的流向趋势确定主流，按此递归得到河流的不同级别，对基于河段组织的水系网结构化，自动建立水系的Horton编码。(3)设计基于Horton码的水系网模型，对结点、河段、河流和河系的数据进行有效的组织。

The invention orginates from the fact that most of the concrete reinforcement loops needed in practice can be divided up into relatively small number of types of loops which are characterized by a predetermined sequence of points of bend with a fixed sense of direction and amount of the angle of bend, in which case the loops of the same type differ from one another only in the lengths of the individual sides of the loops between the points of bend, or from one end of the loop to the first point of bend, and from the other end of the loop to the last point of bend.

问题补充：不要软件翻译的，最好自己翻译，起码通顺的这项发明orginates的是钢筋混凝土的循环需要在实践中最可分为相对的，是由弯曲点的序列特征与预定的方向和角度的数额固定感循环类型的为数甚少的事实弯曲，在这种情况下，同类型的循环，从彼此的不同只是在弯道之间，或从一个循环结束第一点弯曲点的循环个人边长，从另一端循环的最后一点弯曲。

Bend：弯曲

例如,将一个盒子"弯曲"(Bend)后又进行"倾斜"(Skew), 但是如果对"弯曲"(Bend)的程度不是很满意,可以迅速回到"弯曲"(Bend)修改处继续进行修改,"倾斜"(Skew)状态会自动随 "弯曲"(Bend)特性的改变而改变,不必担心修改物体后无法挽回,
