%X In order to investigate the spatial distribution of the Potamogeton crispus turion in Xuanwu Lake,a total of 52 samples were collected by the grid method.In each sampling site positioned by GPS,four samples of P.crispus turion from 15cm depth under surface sediment were collected,summing the data to represent turion density of the site.Spatial variation of P.crispus turion density in the Lake was studied by using the geostatistical component of ArcGIS.Compared with traditional statistical methods,the geosta...
