渭河流域水文变异驱动因子分析研究

Analysis and Study on Driving Factor of Hydrological Variation in Weihe river basin

水文环境在整个生态系统中作用显著,人类的自然活动等涉水行为已威胁到水文系统的稳定性,最终影响生态环境的系统性。文章基于水文变异不同诊断模块,综合多项成果对渭河流域水文系统的变异综合诊断分析,从气象条件、水利工程和水土保持等方面进行研究,探索水文系统变异的各驱动因子。研究成果对于指导流域水文变异研究具有一定的参考价值。

The hydrological environment takes a significant role in the whole ecosystem function, human natural activities such as wading behavior has threatened the stability of the hydrological system, finally influencing the systematicness of the ecological environment. Based on different diagnostic modulus of hydrological variation, the study diagnoses and analyzes comprehensively the hydrological variation of the Weihe river basin based on some achievements, and researches from aspects of meteorological conditions ,water conservancy project and soil and water conservation, exploring each driving factor of the hydrological system variation. The research results have certain reference value to guide the hydrological variation of river basin.
