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。
In this paper, the spatio-temporal variations of environmental factors such as water temperature, salinity, nutrients (active silicate SiO3-Si, active phosphate PO4-P, nitrate NO3-N) in the summer intertidal zone in Fildes Peninsula, Antarctica were analyzed and discussed. The spatial distribution of water temperature is the highest in the climax area, the next in the mid-tide area, and the lowest in the low-tide area. The temperature and the exposure time of the intertidal zone are the main factors that affect the water temperature variation in the intertidal zone. The salinity spatial distribution is the lowest in the climax zone, the next in the mid-tide zone, and the highest in the low-tide zone. The infiltration of snow melt into the intertidal zone will affect the spatial distribution of salinity in the intertidal zone. The spatial distribution of nutrient content in the tidal zone was lower than that in the low tide zone in the tidal range, and the nutrient in the intertidal zone was not mainly derived from the terrestrial source.
