摘要
在高潜水位地区,煤炭井工开采会导致大面积积水区出现,复垦治理后,有些塌陷积水区被改造为精养鱼塘或网箱养鱼区。为研究煤炭开采沉陷对矿区生态环境的影响,采用随机取样法对采煤塌陷区水体包括塌陷积水区、精养鱼塘、网箱养鱼区这3种水域进行水样的采集,采用计数法进行浮游植物的定性和定量分析。结果表明,煤炭开采引起的塌陷区水体具有如下特征:采煤塌陷区水体目前均处于富营养化水平,为严重污染状态;各水体的物种丰富度都比较低,个体分布不均匀;影响塌陷区水体浮游植物的主要因素是该区塌陷积水前的耕地土壤肥力。
The exploitation of coal resources made the ecological environment of mining areas destructed, especially in the high groundwater level Regions, large areas of subsidence water appeared. After land reclamation, some subsidence water was transformed into little ponds, others Used for extensive farming. In order to understanding the effect of coal mining subsidence on the ecological environment, the author randomly sampling the water of mining areas, which included the subsidence water, fishpond water and the water of extensive farming areas. And the phytoplanktons was analyzed by counting method. The results showed that the water of the coal mining subsidence areas had following characters： those three kinds of water were at the level of eutrophication and heavily polluted, the species richness was relatively low, the distribution of individuals was uneven, the main factors of which were soil nutrients in the farmland before it subsidence.
