【摘要】 以2004年夏季(4～8月)对淮南矿区三个不同塌陷时序塌陷塘每月一次的现场调查为基础,分析了采煤塌陷塘水质、不同理化因子的状况及相关关系,研究表明塌陷塘水质金属指标普遍不超标,营养盐含量较高,主要为P限制,同时划分了其主要的影响因子,这为其以后发展水产业和持续利用渔业资源提供了一定的理论基础依据。更多还原

【Abstract】 Based on the monthly investigations in three subsidence pools which they have different histories from Apr.to Aug.in2004,different physical and chemical characteristics and their relations about this sepecial water body are analyzed,on this research it find that the iorn indices aren’t overrun their standards,but the nutrition indice such TP(the content of total phosphorus)and TN(the content of total nitrogen)are higher,the water quality are confined by phosphorus,at the same time the primary influencing factors are pointed out.This study provides a theoretical basis for fishery and sustainable use of fishery resources.更多还原
