Description :
Discharge from the largest karst spring in north China, the Niangziguan Springs, has been declining since the 1950s. This paper examines the response of these springs to climatic change and anthropogenic influence by attempting a model-based discrimination between phases in the stream discharge record. In Niangziguan Springs Basin, the exploitation of karst groundwater began in 1979. Accordingly, the spring discharge data were divided into two phases: pre-1979 and post-1979. Using grey system theory, a discharge model was estimated for the first phase. Then extrapolating the model and using a water balance calculation, the AA. discerned the respective effects on climate change and human activities on depletion of spring discharge for the second phase.
