采煤矿区不同塌陷塘水域生态环境特征分析

通过对淮南矿区不同塌陷年龄的采煤塌陷塘的水生态环境监测,分析了不同塌陷年龄塌陷塘的主要限制性因子和塘内浮游植物种类组成及其生长的限制性因子,结果表明:不同塌陷年龄的塌陷塘中主要限制因子各不相同,但TP在各塘中均占据主要的限制性因子地位,塌陷塘主要为P限制型;浮游植物组成方面绿藻和蓝藻均占据优势地位,但各塌陷塘浮游植物组成与主成分因子间的关系并不一致,其受限因子也有所不同。

Analysis of Aquatic Environmental Characters in Different Excavating Coal Mine

Based on the water entironment monitoring of the pond in excavating coal mine which they were formed in different periods in Huainan in 2004 to 2005,the primary limitative factors and the composing of the phytoplankton as well as their living limited factors were analyzed in the different pools. The results showed the limitative factors were different except the concentration of total phosphorus in each pond. The result illuminated that the ponds were P-limited. The chlorophyceae and cyanophyceae occupied the dominant status in the composing of the phytoplankton, but the limitative factors of the phytoplankton had distinctive difference among each ponds, as well as the relations between it and the principal component factor.
