The relationship between spatial patterns of macrobenthos community characteristics and environmental conditions（salinity, temperature, dissolved oxygen, organic matter content, sand, silt and clay） was investigated throughout the Gorgan Bay in June 2010. Principal components analysis（PCA） based on environmental data separated eastern and western stations. The maximum（4 500 ind./m2） and minimum（411 ind./m2） densities were observed at stas 1 and 6, respectively. Polychaeta was the major group and streblospio gynobranchiata was dominant species in the bay. According to Distance Based Linear models results, macrofaunal total density was correlated with silt percentage and salinity and these two factors explaining 64% of the variability while macrofaunal community structure just correlated with salinity（22% total variation）. In general, western part of the bay showed the highest number of species and biodiversity while, the highest density was found at sta. 1 and in the middle part of the bay. Furthermore, relationship between diversity indices and macrobenthic species with measured factors is also discussed. Our results confirm the effect of salinity as an important factor on distribution of macrobenthic fauna in south Caspian brackish waters.

地球早期,尤其是冥古代-早太古代时期大陆地壳的性质、范围和产生机制一直是地球科学研究的前沿问题。在已有的大陆地壳生长模式中,有些认为当前大陆地壳的60%~80%在30亿年前就已形成,而有些则倾向于一个渐进的地壳生长模式。不论哪种模式,大都基于锆石的形成年龄或者壳幔系统的放射性同位素演化。然而,由于不能限定再循环物质的量,锆石仅能限定地壳生长的年龄下限。相反,放射性同位素体系演化曲线可有助于了解地幔亏损过程,壳幔分离和地壳再循环作用。基于长寿命同位素(sr、Nd及Hf)体系在壳幔间的互补性,前人估计要达到当前地壳和亏损地幔间的组成平衡,只需25%~50%的地幔物质经历熔体抽提。
