On the base of Pearson correlation coefficient indicate that the connection between IBI and CQHEI is higher than IBI and ISC of Juoshuei river basin. To the section of the upper and middle reaches, we suggest choosing simple and convenient SIAM to be the standard for environment in the future. But due to the type of ecosystem has a tendency to estuary ecosystem at the lower reach of Juoshuei river basin, SIAM is more unsuitable for evaluating at the reach. The correlation between each index is not notable, so we suggest seeking other assessment method as comparative environmental standards.

由指标相关性讨论可知栖地品质与生物完整性相关性较高(r=0.649)，水质状态与生物完整性相关性则较低(r=0.267)，对於中上游河段部分，建议日后进行河川生态环境调查时可选择简便易用的SIAM模式做为标准；下游近海河段则因河川型态渐转变为河口生态系的型态，故适用於溪流生态系的SIAM在适用性上较差，各指标间相关性并不显著，建议可寻求其他评估模式做为环境品质的判断标准。

In order to diagnose disease caused by muscovy duck parvovirus rapidly and accurately, and at same time, further study the taxonomic relationship between muscovy duck parivovirus and goose parvovirus, two pairs of PCR primers (LHMP1/LHMP2 and LHGP1/LHGP2) were designed respectively base on complete nucleotide sequences of Muscovy duck and Goose parvoviruses registered in the GenBank, The LHMP1 for the upper one and the LHMP2 for the lower one, corresponding to the specific nucleotides sequence 454-472 and 1173-1155 respectively in MDPV, and the LHGP1 for the the upper one and the LHGP2 for the lower one, corresponding to the specific nucleotides sequence 454-472 and 1173-1155 respectively in GPV.

为了能快速、准确地对番鸭细小病毒病进行诊断，同时为了能进一步弄清番鸭细小病毒与鹅细小病毒在分类学上是一种怎样的关系，比较GenBank中MDPV和GPV的基因序列，针对这两种病毒左阅读框编码非结构蛋白基因序列的相同区段，分别构建两对PCR引物。第一对引物LHMP1／LHMP2是根据MDPV的基因序列设计的，上游引物针对MDPV基因序列的454～472；下游引物针对基因序列的1173～1155，为19个碱基，扩增跨幅为719bp。
