Theinformation provided by this method includes the composition and abundance of the aquatic macrophyte flora.For a complete assessment of ecological status, other elements of biological quality should also be assessed.The general principle of the approach described in this European Standard may also form the basis for themonitoring and assessment of macrophytes in lakes, for example, for conservation purposes.【中国标准分类号】: Z16【国际标准分类号】: 13_060_70【页数】: 24P.;A4【正文语种】: 英语 | 欢迎光临 世界资料网论坛 (http://bbs.infoeach.com/) | Powered by Discuz!
