Abstract:The spatial distributions of mangrove populations were studied at Yingluogang of Guangxi,China,by continuous sampling along 360m long strips.The main results are as follows:(1)The soil texture,nutrients and salt content vary remarkably along the sampling strip,from the inner seawall to the outer bare beach where no mangrove occurs.The values of organic matter,total nitrogen,hydrolysable nitrogen,total phosphorus,available phosphorus and total salt are 1.11%~6.67%,0.021%~0.136%,41.6~203.7mg/kg,0.0087%~0.0309...
