7、logy,JinanUniversity定量采样方法：用采水器取水面以下0.5m至离湖底0.5m的混合水样10L。定性样品用孔径为6μm或10μm的浮游生物网过滤获得。RequiredEquipmenthydrobio.jnu.edu.cnInstituteofhydrobiology,JinanUniversity边长1M45cm9cm63cm自制浮游植物网hydrobio.jnu.edu.cnInstituteofhydrobiology,JinanUniversity不同水体定量样品的采集对于一般富营养化调查，取水面以下0.5米处的水样

8、即可。对于多样性调查，则要取生物多样性更高的地方，所以多采取混合水样。没有分层的浅水湖泊，每1米一个样取至水底上方0.5米处。有分层的水体，应取至透明度的1.5倍且
