非富营养化淡水系统中被忽略的生态系统驱动因素:可溶性腐殖质－简要的回顾与展望

HS are complex organic molecules comprising thehighest proportion(50%—80%)of dissolved organicmatter(DOM)in all freshwater ecosystems.In any non-eutrophicated freshwater ecosystems and with concentra-tions between1and100mg/L,occasionally even more,for instance:Australian wetlands upto300mg/L DOC1],Brazilian coastal lagoons160—200mg/L DOC2],HSex-ceedthe organic carbon of all living organisms byroughlyone order of magnitude3—6].Jones(1998)7]emphasizesthat all freshwaters contain so…
