论文对西北地区各大型内陆盆地地下水系统中含水系统的结构特征和地下水径流特征进行了对比分析.利用模糊数学方法对内陆盆地各流域地表水与地下水相互转化模式进行了识别,结果表明,各流域地表水与地下水相互转化不仅在形式上是一致的,而且在量化比例上也具有非常的相似性.文章还就水文环境变化和人类活动对地下水系统演化规律的影响进行了探讨.在此基础上,对西北地区内陆盆地水资源合理开发利用提出了一些合理化建议. |

Northwest China is lack of water resources and ecological environment is fragile.Owing to unreasonable development of water and land resources,many problems of ecological environment (such as land desertification,salinization,etc.)have occurred.The evolution law of groundwater system must be followed for improving ecological environment and reasonable exploitation and utilization of water resources.This thesis analyzes and compares the characteristics of the aquifer systems and groundwater runoff systems of the various large interior basins in Northwest China. The transformation modes of surface water and groundwater are identified using method of fuzzy mathematics.The result shows that the transformation modes are not only unanimous in form but also analogous in the proportion of transformed quantity.The impacts of hydrologic environment and human activity on groundwater cycle and evolution laws are discussed.Finaily,the thesis gives some proposal about the rational exploitation and utilization of water resources in these basins. |
