外来红树植物无瓣海桑生物学特性与生态环境适应性分析

Biological characteristics and ecological adaptability for non-indigenous mangrove species Sonneratia apetala

根据近年来的调查观测数据和收集国内外有关资料较全面地论述外来红树植物无瓣海桑的形态特征、地理分布、生物学特性 (包括物候、种子品质与苗木生长、苗木抗逆性、种苗扩散性、种内竞争特点 )和生态环境适应性 (包括气温、光照、盐度、潮滩与土壤 ) ;据此分析了无瓣海桑生态入侵的可能性 ,并提出相关的建议 。

The paper described in detail the morphology, geographical distribution, biological characteristics (including phenology, seed quality, seedling growth, antiadversity, seedling diffusibility and intraspecific competition) and adaptability of ecological factors (such as temperature, illumination, salinity, tide mudflat and soil) of Sonneratia apetala according to investigated data in recent years and collected information at home and abroad. The paper also analysed the probability of ecological invasion and put forward a suggestion. It will provide a theoretical basis for further investigation on the ecological effects and reasonable development and utilization of non-indigenous mangrove species S. apetala in China in the future.
