| 摘 要： | １９９６年８月，１１月各一次调查火溪河的底栖动物。共采集到到底栖动物３９种，其数量为８７．３ｉｎｄ／ｍ＾２，优势种类为方巢石蚕、四节蜉、小蜉、光石蝇和溪在非议 五种。火溪河底栖运行具有明显的山地型、流水型特点、时空分布一致。应用ＢＭＷＰ记分，ＢＢＩ／ＦＢＩ生物指数和Ｓｙａｎｎｏｎ多样性指数对脂河水质进行评价，表明水质清洁。作者建议以方巢石蚕７０．０ｉｎｄ／ｍ＾２作为火溪河水质清洁与轻污的一个界定值

| Abstract: | The benthos in the Huoxihe River were investigated in August and November of 1996. 39 species of benthos were found with the density of 87.3 individuals / m2 or 0.9504mg / m2 The dominant species included Branchycentrus sp., Bactis sp., Ephemerella sp., Togoperla sp. and Antocha sp. The benthos in The Huoxihe River were typical species in the lobe water of mountain areas and their time and space distribution was in agreement. The water quality was demonstrated to be clean by the BMWP system, BBI/ FBI index and Shannon diversity index. It is suggested that the density of 70.0 individuals/m' in Branchycentrus sp. be the critical point for the clean water and the lightly-polluted water in The Huoxihe River. |
