Analyzing Influences of the Ecological Factor on the Growth of Kandelia on a Coastal Shoal

通过沿海滩涂生态因子对秋茄生长的影响分析 ,认为海岸地形、土壤盐度、滩涂潮位、土壤类型、立地方位均对秋茄生长产生不同影响。海岸地形决定其生存空间 ;土壤盐度、滩涂潮位影响其生长发育 ,决定其成活保存率 ;土壤类型、立地方位主要影响生长量。其影响大小顺序为海岸地形 >土壤盐度 >滩涂潮位 >土壤类型 >立地方位。

Through the analysis of influences of the ecological factor on the growth of kandelia on a coastal shoal,this article points out that the coastal topography decides its living space;the soil salinity and shoal tidemark influence its growth and development and decide its survival rate;and the soil type and site bearings mainly influence its increment.The influence sequence is as follows:coastal topography>soil salinity>shoal tidemark>soil type>site bearings.
