中文摘要:为查明四川黄龙核心景区钙华层内水体的循环交替过程及水循环系统结构,采用野外实地调查、水循环断面监测等方法,分析任一监测断面的地下水径流量和地表水流量(二次转化泉形成)组成、循环段内的补给和排泄特征,理清各水循环系统的发育规模、层级。分析结果表明,丰水期水循环系统层级最为复杂,分为区域-局部-场地三个循环层级,以局部循环为主。以7月为典型月,景区内水循环主要受控于4个串联发育的局部地下水循环系统,区域地下水循环系统在接仙桥以北地段发育,各循环段内的充水彩池群为补给区,出口为流量较大的钙华二次转化泉,地下水在钙华层内径流,钙华层底部和两侧为隔水边界;争艳池以南场地水循环较多;景区水循环系统结构年动态变化较大,仅在丰水期达到动态平衡状态。转花池泉群、黄龙沟东坡泉群、黄龙沟地表水及地下水构成了驱动核心景区水循环系统的全部水量,接仙桥、涪江右岸为排泄口。黄龙核心景区水循环在丰水期形成动态平衡,其余时段处于不稳定流动状态。

Study on the structure of multi-layer water circulation system in the core scenic spot of Huanglong
Abstract:In order to find out the water circulation process and water circulation system structure in the travertine layer in the core scenic spot of Huanglong, Sichuan,in this paper, the methods of surveys and water circulation section monitoring were adopted to analyze the composition of groundwater runoff flow and surface water flow,which are formed from secondary conversion spring, in monitoring section and the characteristics of recharge and discharge in the circulation section,so as to obtain the development scale and level of each water circulation system. According to the 2019 survey results and data analysis of 16 water monitoring stations, the results showed that the structure of water circulation system is the most complex during the wet season, and it is divided into three levels of regional circulation, local circulation and site circulation, with the local circulation as the main in scale. Taking July as a typical month, the water circulation in the scenic spot is mainly controlled by four local groundwater circulation systems developed in series. The regional groundwater circulation system developed in the north area of Jiexian bridge. The Chongshuicai pools between each circulation sections were the recharge areas, and the outlet was secondary conversion calcareous spring with large flow. Groundwater flows in the travertine layer and the bottom and both sides of the layer are water-proof boundaries. There are 5 site water circulation systems in the south of Zhengyan pool. The dynamics changes of the water circulation system structure in the scenic spot are great, and it reached the dynamic equilibrium state only in wet season. The surface water and underground water of Huanglong stream constitute all the water volume that drives the development of the water circulation system in the core scenic spot,and the water in the scenic area is completely discharged in Jiexian bridge and the right bank of Fujiang. The water circulation in the core scenic area of Huanglong reaches a dynamic balance during the wet season, while which is in an unstable flow state in other periods.
