社会经济发展对永定河流域(北京段)与温榆河流域地下水的影响分析

以永定河流域（北京段）和温榆河流域为对象,通过历史数据收集、整理和统计分析,研究流域内地下水环境的历史变迁和社会经济发展对其的影响.结果表明,1978—2008年间永定河流域（北京段）和温榆河流域均存在地下水埋深加深、地下水资源和地下水开采量略增、地下水水质恶化的趋势.1940—2008年间两流域的地下水埋深、地下水资...

Impact of socioeconomic development on groundwater in Yongding River (Beijing section) and Wenyu River Watersheds

The evolution of groundwater regime and the impact of socioeconomic development on grounderwater of Yongding River (Beijing section) and Wenyu River watersheds were investigated and analyzed in this study. Results clearly showed that a trend of deepening groundwater embedment depth, increasing of groundwater resource and its extraction occurred in these two watersheds from 1978 to 2008. Pearson analysis results based on data of groundwater embedment depth, groundwater resource, groundwater quality, and socioeconomic development from 1980 to 2008 showed that the deepening groundwater embedment depth of the Yongding River was significantly affected by both the outflow of Guanting Reservoir and the waterflow of Yongding River at Sanjiadian station , which their Pearson correlation values were at -0.677(p<0.01) and -0.659(p<0.01), respectively. Different from the results mentioned above, GDP per capita and urbanization rate in the Wenyu River significantly influenced the embedment depth and quality of its groundwater, e.g., their Pearson correlation values were at 0.910 (p<0.01) and 0.919 (p<0.01), respectively. In a word, these results indicated that outflow of Guanting Reservoir and waterflow of Yongding River markedly affected on Yongding (Beijing section) groundwater embedment depth, compared with the socioeconomic development significantly impacted on the groundwater regime in the Wenyu River.
