人类活动对地下水资源转化关系的影响

TRANSFORMATION OF GROUNDWATER RESOURCES UNDER THE INFLUENCE OF HUMAN ACTIVITIES

本文以石羊河流域为背景，分析在一定的水文及水文地质条件下人类活动对地下水转化关系的影响．并推求出石羊河流域不同灌溉开发水平下的上游山水与中游泉水间的月推移年径流量互相关关系．结果表明，灌溉开发水平的提高，虽然可以加激地下水资源转化，夺取一些无效蒸发量，提高水资源利用率，但最终将导致掠夺性开发利用和生态环境的恶化．因此，寻求人类活动影响下的地下水资源转化规律对区域水利规划及生态环境评价十分重要．

Transformation of groundwater resources is under the influence of human activities, which of Shiyanghe basin is discussed, on the basis of the particular hydrological and hydrogeological environment.The cross-correlation of yearly runoff between the mountain streams and the plain spring stream is calculated. It is concluded that the ineffective evaporation is decreased and the efficiency of utilization of water resources is higher with the increasement of the level of irrigating exploitation. Meanwhile, it inevitably results in overexploitation and many environmental problems. Therefore, it is very important to consider human activities.
