In　this　paper,　the　Log-log　semivariogram　and　theoretical　models　of　Geostatistics　and　fractal　theory　were　applied　to　study　the　mosaic　spatial　pattern　of　macrophytes　community　and　its　different　characters　on　different　scales　in　littoral　zone　of　the　Baoan　Lake,　Hubei　Province.　The　macrophytes　in　the　littoral　zone　with　a　square　area　of　25　600　m2,　which　was　divided　in　to　1　024　grids,　were　investigated,　and　the　macrophytes　species　in　every　grid　were　recorded.　If　the　species　was　discovered　in　the　grid,　the　variable　of　the　grid　had　a　value　of　1,　otherwise,　it　was　0.　The　community　had　a　value　of　the　total　species　discovered　in　the　grid.　By　the　method,　the　sampling　results　of　Vallisneria　spiralis,　Ceratophyllum　oryzetorum,　Myriophyllum　spicatum　and　the　community　were　made　into　four　worksheets.　With　help　of　the　software　GS+　for　Windows　to　treat　these　worksheets,　we　got　their　log-log　semivariogram,　isotropic　model,　anisotropic　model,　isotropic　fractal　dimension　and　anisotropic　fractal　dimension.　According　to　the　results　of　isotropic　models,　the　exponential　models　of　Vallisneria　spiralis　and　Myriophyllum　spicatum　indicated　their　contagious　distribution　with　a　high　proportion　of　spatial　structure,　which　indicated　that　their　distribution　changed　lesser　at　microscale.　In　their　range　of　48.6m　and　34.2m　respectively,　they　had　a　spatial　autocorrelation.　Isotropic　models　of　Ceratophyllum　oryzetorum　and　the　community　were　linear,　and　their　proportions　of　spatial　structure　were　low,　indicating　their　great　change　at　microscale　and　their　moderate　contagious　distribution.　The　isotropic　fractal　dimension　and　anisotropic　fractal　dimension　results　indicated　the　dominant　pattern　of　Vallisneria　spiralis　in　the　direction　of　NE-SW,　the　dominant　patterns　of　Myriophyllum　spicatum　and　Ceratophyllum　oryzetorum　in　the　direction　of　N-S,　and　the　community＇s　dominant　pattern　in　the　direction　of　NW-SE.　Compared　with　other　analysis　tools,　the　method　had　advantages　in　deciding　whether　the　community　components　had　a　spatial　autocorrelation　and　in　quantitatively　classifying　the　aggregation　density.　It　provides　us　a　new　way　to　quantitatively　describe　the　pattern　of　the　macrophytes　community.
