Abstract: Energy and material flux in Lijia village farmland ecosystem were analysed and evaluated.The results showed that the Lijia village,which used to be affected by seawater intrusion,after harnessed by agro-eco-engineering,its system function has been strenthened up,and its structure tends to reach rationalization.Then some problems which should be paid attention to are pointed out concerning eco-agricultural development in the region.
