贵州省中部喀斯特山区城镇化对浅层地下水氮磷的影响及评价
Influence of Urbanization on Concentrations of N and P in Shallow Groundwater and Its Evaluation in Karst Hilly Area of Guizhou Province
摘要
Abstract
By selecting the research region located in Houzhai River basin of Puding County in central karst region of Guizhou Province,water samples of perennial spring water in forest area,farming area,rural residential area and town residential area were collected and analyzed to investigate the influence of urbanization on the N and P concentrations in shallow groundwater and the change of water quality.Results show that the concentrations of NO-3 and NH+4 in shallow groundwater were within 1.18~43.6 and 0.017~0.290 mg/L,respectively,of which the concentrations of NO-3 and NH+4 in the shallow groundwater of forest area,farming area and rural residential area were in the range of the class Ⅲ water quality,but the concentration of NH+4 in town residential area was beyond the class Ⅲ water quality.The concentration of total P was within 0.012~0.682 mg/L,but in rural and town residential areas,the concentration of total P exceeded the limit of water quality.The contents of N and P in groundwater increase in the process of urbanization,which exerts a significant impact on groundwater quality in the karst hilly area.关键词
