| Karst Water Resources in Typical Areas of China and Their Eco-hydrological Characteristics |
| This paper deals with different karst water features and water resources in southern and northern China. In the main karst regions of southern China, there are over 3,358 well developed karst subterranean river systems with total discharge of about 420×108m3 in the dry season; nevertheless, the exploiting rates are only 8%～15%. In the main karst regions of northern China, over 100 large karst spring systems cover catchment areas from 500 km2 to over 4,000 km2 in size , of which the average discharges range from some 1 m3/s to 13 m3/s, and the exploiting rates are 70%～80%. The discussion on the eco-hydrological features of some typical karst regions in China includes six aspects, namely, water environment, ecological features, materials and structures between parent rock and soil, bio-geological processes and spore-pollens. The qualitative evaluation of eco-geology and rocky desertification in karst regions should be based on the main karst ecological conditions and artificial impacts. |
