摘要
本文描述了海南岛海涂土壤的种类和分布,并对海涂土壤的基本特性——物质组成、理化性质,以及海涂土壤的养分水平等做了详细分析。文中还根据本区海涂土壤及其生态环境特征,对海涂土壤的开发利用进行了讨论。
Hainan Island,which lies in the South China Sea,is the second largest island of China with more than 1600km coastline and about 1333km2 beach soil.The exploitation of the island's beach so far has been mariculture,baysalting and tourism.Based on the survey data from Guangdong Coastal Beach Resources survey conducted before 1987,the main characteristics of the beach soil are as following.1)The soil texture is fundamentally of sand and heavy loam with physical clay making up 56.7% at most of the content.2)The organic matters generally count for 1%-2% of soil content,with the maxima being 14.6% (as to high-acid-tidal-flat soil).The ratio of C:N varies between 10-39.3) Salt possesses 0.04%~4.13% of soil content and pH varies from 2.4 to 8.3.
