摘要
砂生植被在浙江海岛见于部分岛屿的砂质海岸，由砂生植物和部分耐砂植物组成。植物区系组成简单，约有野生维管植物２７１种，隶属于６７科１９１属。地理成分复杂，热带亲缘性明显。植被外貌整齐、低矮，季相变化明显，层次结构简单。植被分布因地区、岛屿、沙滩和立地而差异较大，具有明显的条带性。虽属隐域植被但地带性烙印清晰。植被演替外因于土壤质地、水分、盐分和有机质含量的变化，属外因生态演替。
The sand vegetation found on the sandy coast of some islands inZhejiang,having a simple floristic composition,is composed of 271 speciesof wild vascular plants, either psammophytes or plants with sandy tolerance,which belong to 191 genera of 67 families.The vegetation, with obviousaspect changes and simple construction,is complex in geographycal elements,regular and low in physiognomy,and is closely related to the tropical flora.It is uneycnly distributed in different regions,islands,sandy beaches andsite conditions,and has banded characteristics.Although an intrazonal ve-getation,it has the obvious brand of the zonal vegetation. In addition,itssuccession,caused by changes in the size of sand grains, moisture content,salinity and organic content of soil,is in the category of exodynamic suc-cession.
