In the present study,we assessed the water quality along a stretch of thewatershedwith considerable economicimportance at the Xindian in Taiwan, using macroinvertebrate assemblages, along with environmental variables. The researchwas carried out at the seven sampling sites (abbreviated asXD1–XD7)where human impacts variedin intensity from upstream tributaries to the downstream of the Xindian watershed from December 2010 toDecember 2011. All variables except for the hardness, pH, dissolved oxygen, conductivity, turbidity, phosphate,ammonia, and alkalinity were significantly different (P b 0.05) between the sampling sites. A total of seventyseven taxa belonging to forty five families within eight insect orders, along with three non-insect invertebratetaxa were recorded, with most representative orders being Ephemeroptera and Diptera. Mean values of thedensity, abundance of macroinvertebrates, Shannon index, Simpson index, and Pielou's evenness were muchhigher in the reference sites, XD2, XD3, and XD4 compared with impacted sites, XD5, XD6, and XD7. Most ofthe benthic metrics were greatest in the reference site compared to the impacted site. Only the compositionmeasures, percentages of Chironomidae and Oligochaeta which are more tolerant to pollution were dominantin the impacted site, XD7. As the results of assessment by different benthic metrics, water quality of Xindianwatershed became gradually worse from upstream to downstream. Generally, our results suggest thatmacroinvertebrate assemblages can be used for assessment of water quality.
