| 摘 要： | 本文对南极菲尔德斯半岛夏季潮间带水温、盐度、营养盐（活性硅酸盐ＳｉＯ３－Ｓｉ、活性磷酸盐ＰＯ４－Ｐ、硝酸盐ＮＯ３－Ｎ）等环境因子的时空变化进行了分析讨论。其水温空间分布，高潮区最高，中潮区次之，低潮区最低；气温和潮间带裸露时间长短是影响潮间带水温变化的主要因子。盐度空间分布特点是高潮区最低，中潮区次之，低潮区最高，陆地融化雪水渗透到潮间带的多少将影响潮间带盐度的空间分布。潮间带营养盐含量的空间分布，中潮区低于低潮区，潮间带的营养盐主要不是来自陆源。

| Abstract: | The environmental factors such as water temperature, salinity, nutrient salts (in the forms of PO 4 P, NO 3 N and SiO 3 Si) in the intertidal zone in summer in the Fildes Peninsula, Antarctica are analyzed. For the spatial distribution of water temperature, it is the highest in the high tide area, the next in the mid tide area and the lowest in the low tide area. The length of the time for the exposure of the intertidal zone and air temperature are the main factors influencing the water temperature change. As to the spatial distribution feature of the salinity, it is the lowest in the high tide area, the next in the mid tide area, and the highest in the low tide area.The amount of snowmelt from land infiltrated into the intertidal zone will influence the spatial distribution of salinity in the intertidal zone. The spatial distribution of the nutrients in the intertidal zone in the mid tide area is lower than that in the low tide area. The nutrients in the intertidal zone are mostly not terrigenous. |
