摘要/Abstract

摘要： 水文情势的自然波动是维系河流生态系统功能性的关键。然而以往的研究缺乏对岷江流域水文情势的全面评估，重点利用具有生态意义的指标来全面分析岷江流域水文情势的演变及生态响应。针对岷江流域本研究采用Mann-Kendall和Pettitt检验法判断水文突变年份。通过2个广义的生态指标（生态盈余、生态赤字），水文变化指标（IHA）和识别突变发生前后生态水文变异特征。借助水文变异程度（D0）和水文情势变化法（DHRAM）评估改变程度。结合Budyko水热耦合平衡理论量化生态水文变化的驱动因素。利用生物多样性指数（SI）来评估岷江水文情势变化下的生态响应。结果表明：（1）岷江流域水文情势在1993年发生突变。（2）岷江流域水文总体改变度达到44%，综合评定为中度改变。（3）水文情势改变导致岷江流域生态盈余减少及生态赤字增大。（4）根据 Budyko理论，发现人类活动对岷江流域年均径流变化的影响占比达到54.20%，为主要影响因素，降雨影响占比为43.88%，蒸发影响占比1.92%，气候变化和人类活动共同导致岷江径流量降低83.83 mm。（5）SI 指标表明人类活动的影响加快了生物多样性指数降低的趋势。研究可以为加强岷江流域生态环境保护和修复提供参考依据，并促进岷江水资源合理高效利用。

Abstract: The natural variation of hydrological regime plays an important role in maintaining the function of river ecosystems.However, previous studies lack a comprehensive assessment of the hydrological regime changes in the Min River Basin. This study focused on a comprehensive analysis of the evolution, driving factors, and ecological response of hydrological regime in the Min River Basin,using indicators of ecological significance.Mann-Kendall and Pettitt’s tests were used to detect the year of abrupt hydrological changes in the Min River basin.Two general ecological indicators (ecological surplus and ecological deficit) and the hydrological change index (IHA) were used to identify the characteristics of ecohydrological variation before and after the abrupt changing point. The degree of hydrological variation (D0) and hydrological regime change (DHRAM) were used to assess the degree of changes.The driving factors of ecohydrological change were quantified by a combination of Budyko hydrothermal coupling equilibrium theory.The biodiversity index (SI) was used to analyze the ecological response to the changesinhydrological regime.The results showed that: (1) An abrupt change of the hydrological regime was detected in 1993.(2)The overall degree of hydrological change was up to 44%, indicating a moderate change.(3)Change of hydrological regime leaded to a decrease in ecological surplus and an increase in ecological deficit.(4)The influence of human activities on the annual average runoff change was 54.20%, while the influence of rainfall was 43.88%, and the influence of evaporation was 1.92%. Climate change and human activities jointly reduced the runoff of the Min River by 83.83 mm, and the human activities were dominant.(5)The influence of human activities accelerated the decline of biodiversity index. This study provideda reference for strengthening the protection and restoration of the ecological environment in theMinRiver, and promoted the rational and efficient utilization of water resources in the area.
