Resource survey of the benthic algae in Zhongjieshan Islands

According to the biological investigation of Zhongjieshan Islands tideland and on the base of advanced principle of dividing of the benthic algae , we studied the species composition and the limits distribution of the benthic algae. The paper also advances some suggestions about how to process the ecology protecting and realize sustained exploitation of those recourse after analysing some interrelated questions about resource peculiarity , exploitation and utilization of the benthic algae in Zhongjieshan Islands tideland.
