Hydrogeochemistry And Its Influence On Evolution At Jiuzhai Valley

Jiuzhai Valley enjoys great prestige in the world and has very important position in the tourist circle. However, in recent years, the discharge of some location of Jiuzhai Valley has obviously reduced, the lake water level dropped, the discharge of waterfall withered.These phenomenas have caused various circles of society to question the sustainable utilization for the tourist resources in Jiuzhai Valley.Aiming at the current situation of declining of Jiuzhai Valley, discharge and water quality are researched especially in the thesis.By surveying in site and collecting a large number of data, more detailed division is carried on to the hydrology unit in Jiuzhai Valley on the basis of forefathers' achievement, and the dynamic characteristic of hydrology is analysesed.Through monitoring the water quality of Jiuzhai Valley in site , analysing in lab and combining the water quality data for many years of Jiuzhai Valley, Jiuzhai Valley water quality dynamic change characteristic is studied , finally calcium ion one-dimensional space model is tried to set up.According to the research, it can be found that Jiuzhai Valley is at corrosion stage at present, water body has the tendency to leak further , some landscape reservation and rehabilitation measures should be taken to delay its decline process as soon as possible.
