Four items of water quality has been collected in field surveys, including PH value, dissolve oxygen, electric conductivity level and turbidity level. Furthermore, 19 species of freshwater fish have been found, of which 10 species are local strains, 4 species are foreign strains, and 1 species is a hybrid strain. The results of calculating and analyzing the water quality index and Index of Biotic Integrity indicate that WQI is estimated from excellent to fair, while IBI is estimated from fair to poor. It has been illustrated that two indexes show different assessment results. Of those WQI index is more reliable than the IBI. IBI index need further modification for the use of water quality assessment in the Tou-Bien-Ken Creek.

现场采集水质资料共4种，包含pH、溶氧、导电度及浊度，鱼类共计19种，其中原生种10种、外来种4种、杂交种1种，经计算之水质指数及生物整合指数研究分析结果发现，调查测站WQI水质评等由特优至中等，IBI评等由中等至差的等级，显示两种指数评分具有差距，WQI指数之评分结果较IBI正确，IBI指数须经修正才能更适用於头汴坑溪之水质评估。

Aiming at the currently shortage of XML streams quality detecting, this paper proposes a new forecasting method of XML streams quality by least squares support vector machines, which is used the method of XML keys' vector matrix as windows, and vector product wavelet transform to multilevel decompose and refactor the XML streams series, that can fulfill real-time checking demand of XML quality, and ensure constraint, consist- ency and integrality. For even more adapting net load, it proposes a control strategy by weight and adaptive adjustment to ensure XML streams quality.

针对当前XML数据流质量检测存在的不足，提出构建XML键的矢量矩阵作为窗口，利用矢量积小波变换多级分解与重构XML数据流，再结合最小二乘支持向量机对XML数据流质量进行预测的一种方法，满足XML数据流质量重构时实时检测的要求，保证XML数据的约束性、一致性与完整性；为了更好的适应网络负载，采取加权与自适应窗口调整等调度策略充分保证XML数据流的质量检测。
