| الوصف: | Restricted by the natural environment and technical methods, the study on the evolution characteristics of karst development and the karst groundwater cycle process in the Qinghai-Xizang Plateau is relatively weak, which restricts the economic development, construction of livelihood facilities and the prevention and control of geological disasters.This paper systematically analyzes the karst development characteristics of the carbonate rock distribution area in the northern part of Kangding in Sichuan Province through the methods of geological survey, chemistry-isotope characteristics analysis of karst groundwater, surface water and precipitation water, spring water flow dynamics and water balance calculations.And the karst runoff zone was identified.The results show that the carbonate rocks in the northern part of Kangding are distributed in the alpine valley area.The distribution of karst strata, the degree of karst development, karst water supply and runoff are mainly controlled by structures.The degree of karst development on the contact zone of soluble and non-soluble rocks and the vicinity of active faults is relatively strong.The karst water flows as pipeline runoff, which is mainly discharged in the form of karst springs.The spring flow is about 1.5×104 m3/d and the flow dynamics are relatively stable.Through the analysis of hydrogeological conditions, the karst water runoff zone of the Tonghua Formation and the karst water runoff zone of the Yala River fault have been identified.Hydrochemistry-isotopic data, karst spring flow dynamics and water balance calculation results show that Yala River water is the main source of replenishment for large karst springs.Karst groundwater mainly flows downstream along the karst water runoff zone of the Yala River fault and is discharged in a concentrated manner. |
