| 摘 要： | 目的]对比定量和定性采样方法的差异,为进行大型底栖动物的采样提供理论基础.方法]2011年10月采用定量采样的彼得逊采泥器和定性采样的D型手网对温榆河流域大型底栖动物进行采样,并分析该2种采样方法大型底栖动物各自物种组成、优势种、密度和生物量.结果]定量和定性采样方法均采集到28种大型底栖动物,有16种相同物种.定性采样中大型底栖动物的密度为7 377ind/m2,大于定量采样中大型底栖动物的密度（6 309 ind/m2）.结论]在定量采样的同时加入定性的采样方法能够更有效进行大型底栖动物群落的研究和评估.

| Abstract: | Objective] To compare differences of quantitative and qualitative sampling methods and provide theoretical basis lor sampling ot macrobenthos. Method] In October 2011, the quantitative sampling Peterson grab and qualitative sampling D-frame net were used to collect macrobenthos in Wenyu River, and com.paratlvely analyzed macrobenthos species composition, dominant species, density and biomass. Result] Both quantitative and qualitative sampling methods were adopted to collect 28 species of macrobenthos, and 16 kinds of the same species. The qualitative sampling macrobenthos density was 7 377 ind/m2 which was greater than the quantitative sampling macrobenthos density 6 309 ind. m2. Conclusion] Combined quantitative and qualitative sampling methods would be more effectively for carrying out macrobenthos community research and evaluation. |
