Analysis Of The Environmental Effects Of The Golmud Area Of ​​water Resources Development

Located in the Mid-South Qaidam basin in the northwest region of China, the origin and pathway of the water resource occurred in the Golmud area has a affinity closer to other inland basins in the study area, which is characterized evidently by the integrity of the water resource, the frequency of pathway change, and the close pertinency between the water resource and ecological environment. The demanding of the water source becoming more and more with the rapid economic development regionally is bound to have a strong affect on the ecological system. Thus, the major problem ahead in the process of the water exploration in the Northwest inland basin is to assure the economic sustainable development as well as make the best use rationally of the valuable water resource.The present study is firstly aimed to shape a 3-dimension geological structural model and offer a precious technical help to build hydrogeologicai model on a space structure of the aquifer. On the basis of the systemic characteristic of the water resource in the Golmud region, the first coupling mathematic model of the water resource has been studied in this paper ,which offer a nonlinear evaporation module to calculate the transpiration on the basis of the Processing Modflow software.Based on the water resource exploration and environmental response, a great number of factors causing the ecological system in the Golmud region have been involved in the model to evaluate the environmental response in the water development and fix the pertinency between those factors and ecological response.Eventaully,the study in this paper indicate that the range of the exploitable quantity in the water origin region is 0. 357—1. 94×10~nm~3/a, and the range of irrigation water is 0. 497~3. 81×10~nm~3/a.With regard to the 4 different inflow, exploration and diversion sequence, the model prediction on the prevention and adjustment of Wenquan reservoir has been made on the basis of the inflow , spill , underwater table range finally to proposal a rational and reasonable development on the water resource in the Golmud region.
