摘要: |
海南岛是我国的第二大岛,面积约32200平方公里。岛上沙质海岸占比例最大,另外泥滩、石砾、岩石海岸亦有所见。由于四面环海,所以海洋性气候较为显著。水温一般较高。与相邻的广东大陆沿岸相比,季节变化及年变化幅度均较小。基本上符合热带性气候的特点。但是,由于受季节风的影响,以及浅水区域较宽和接近大陆,沿岸水温和气温的年较差和日较差较大,局部地区具有一些大陆性气候的特点。海南岛的潮汐类型是混合潮,潮水幅度通常不超过3米。
1959年11月-1960年2月,作者参加了中国科学院海洋研究所生物考查组到崖县的榆林、马岭,陵水县的新村,万宁县的港北港,乐东县的莺歌海,文昌县的抱虎角、铜鼓角以及海口市的盐灶、北港、苍头前等地进行了调查采集。为了使原有的材料得到更进一步的充实,1962年3-5月,又到崖县的榆林,陵水县的新村以及临高县的新盈,东方县的八所进行补充调查。本文的主要目的在于潮间带藻类进行定性及定量的研究,并结合各地区不同的潮汐类型、潮水幅度等环境条件的具体影响,进一步探索藻类分布上的特点。 |

Abstract: |
Hainan Island lies between lat.18°09'一20°02'N and 1oog.108°36"-112°02'E.Its sea temperature at surface is rather high, the February monthly mean is 22℃ while August is 29℃. Both of its seasonal and annual variations are small. The types of tides are irregular or rather mixed, the tidal range is not over 3 m usually.
Taking Maling (Yaxian) as an exemple, basing 'On the principles of Vaillant,we have discussed the zonation of the rocky coast between tide marks of Hainan Island. The belt from the highest high water (H. H. W.) to the lowest high water (L.H.W.) is called upper littoral belt, that from L. H. W. to highest low water (H.L.W.) is called mid-littoral belt, whereas that from H.L.W. to datum point is called lower littoral belt. Judging from the different cases each belt may be subdivided into several sub-belts. |
