Abstract

Basic ecological characteristics including water body,soil and biology and their correlativity were systematically studied by field investigation on the sampling belt from estuary of Lishui River to Muping Lake.The results showed that: (1) Current velocity decreased almost linearly from the estuary to central lake.Water depth was high in estuary and low in central lake.Other indices in water body such as transparency,NO₃^-N,NH₄⁺-N,total N and total P were maintained fluctuation within a range.(2)The soil in central lake contained higher organic matter,N and P contents,while relatively lower soil organic matter,N and P contents were found in estuary.(3) Water plants could not survive in estuary,and central lake was the main regime for the growth of water plants,where had higher species richness,biomass and biodiversity.(4) The favorable hydrological and soil environments such as appropriate water flowing and fertile soil provided suitable conditions for the growth of water plants,and high current velocity and infertile soil in the central lake were the main reasons explaining for the inexistence of water plants.Correlative analysis showed that mutual effects existed among water physiological and chemical characteristics,soil physiological and chemical characteristics and biological characteristics,and that current velocity was the decisive or key factor in regulating the changes of ecological characteristics.
