• The recognition and measurement of social , economic , and environmental benefit are studied and concrete expressions of these three objects are given ; according to different features of water users and water sources , the concepts and calculation methods of water use fair coefficient of water users and water supply sequence coefficient of water sources are presented ; the concept and calculation method of accordant coefficient of water environment and economic system are also put forward and it is considered as a condition of constraint ; the method to calculate discharge amounts of key contaminants in a planning standard year is brought forward ; on the basis of analyzing characteristics of the model for optimal allocation of regional water quality and water quantity , the method based on matlab optimal toolbox to solve the model is discussed
  模型中考虑了社会目标、经济目标、环境目标的识别和度量方法，给出了三类目标的具体函数表达式；根据用户特性和水源特性的不同，引入了用户用水公平系数、水源供给次序系数的概念和度量方法；由于区域水环境与经济的协调发展是区域可持续发展的核心内容，因此本文提出了水环境经济协调发展度的概念，并给出了相应的计算公式；对规划水平年区域重要污染物排放量进行了计算，并以约束条件的形式予以考虑；分析了区域水质-水量联合优化配置模型的大系统、多目标、非线性等特点，探讨了基于matlab优化工具箱的模型求解技术和方法。
• The identification rate of the former could be above 90 % , whereas the later is below 80 % . for three kinds of targets involving sand , grit and sullage , the feature of singular values excels that of invariant moment , the identification of the former could be to 92 % , whereas the later is 84 % . analyzing the features this dissertation extracts , we can find that the features of rock and sullage are more similar , so do pebble and grit , and the features of sand are obviously distinguished
  分类结果发现，对于以上五类目标，利用直方图有关参数作为分类特征比奇异值特征有效，前者效果可达90以上，而后者低于80 ；对于沙、砂砾、淤泥三类目标而言，奇异值特征比不变矩特征更为有效，前者效果可达92以上，而后者为84 ；从本文中抽取的特征如直方图的参数以及奇异值来看，岩石与淤泥的特征比较接近，而卵石与砂砾的特征比较接近，沙的特征则与其他四类有明显区别。
