    摘要:

    利用3H的示踪作用对珲春盆地浅层地下水更新速率进行计算,为该地区制定地下水开发利用模式和水资源环境承载力研究提供科学依据。结果表明:总体上,珲春盆地大部分地区浅层地下水更新速率大于8%/a,可更新能力较强。珲春盆地东北部平安村、新华村、马新村和东部的红星村、电线村、东兴村等山前地区以及八一村、八二村等地浅层地下水更新速率大于10%/a,可更新能力较强;七户洞村、八棵树村、永丰村、立新村、新农村、柳亭村等地浅层地下水更新速率为8%/a10%/a,可更新能力减弱;八家子村、西崴子村、孟岭村等珲春河下游地区浅层地下水更新速率小于8%/a,可更新能力最弱。更新速率为大于10%/a、8%/a10%/a、小于8%/a的地下水分布面积占珲春盆地总面积的比例分别为67%、26%、7%。

    Abstract:

    The 3 H method was applied to determine the renewal rate of shallow groundwater in the Hunchun Basin , which would provide basis for the study on the groundwater resource exploitation and utilization model and carrying capacity in the Hunchun Basin. The study results show that the renewal rate of the shallow groundwater in most areas of Hunchun Basin is faster than 8%/a in general and the groundwater renewability is strong. The shallow groundwater renewal rate is faster than 10%/a in the villages of Pingan, Xinhua and Maxin in the northeast, the villages of Hongxing, Dianxian and Dongxing in the east, and the villages of Bayi and Baer, which means groundwater renewability is strong. The shallow groundwater renewal rate is 8%/a -10%/a in the villages of Qihudong, Bakeshu, Yongfeng, Lixin, Xinnong and Liuting, which means groundwater renewability is weaker. The shallow groundwater renewal rate is slower than 8%/a in the villages of Bajiazi , Xiwaizi and Mengling along the lower reaches of the Hunchun River, which means groundwater renewability is weakest. The groundwater distribution areas which are faster than 10%/a, during 8%/a-10%/a and slower than 8%/a respectively account for 67%, 26% and 7% of the total Hunchun Basin.
