| 风景区人文经济发展对自然景观保护和开发利用提出了特定需求，在此背景下，针对山区河流泥石流防治措施滞后的问题，为了探索一种既能重构近自然生态系统功能又具有经济成本优势的近自然防治措施，通过深入的野外调查和分析，研究了山区河流自然发育的阶梯-深潭系统在提高大型水流能量耗散率方面的作用，探讨了其消能效率与流量的关系，评估了人工阶梯—深潭系统在防治泥石流及稳定河床方面的功能。研究发现，随着流量的增加，人工阶梯—深潭系统消能效率也随之提升。该系统还具有无可比拟的重构近自然生态系统的景观效应和经济成本优势。基于以上研究结果，建议规划设计单位积极采用人工阶梯—深潭系统在风景区重构近自然生态系统，从根本上稳固河床控制河谷下切，达到防治泥石流灾害的目的。 |

| Under the background of human economic development in scenic areas puts forward specific demands for the protection and development of natural landscapes in response to the lag in mudslide prevention measures for mountain riversTo explore a kind of near-natural control measure，which can reconstruct the function of near-natural ecosystem and has economic cost advantageThrough extensive field surveys and analyses，we have studied the role of naturally occurring step-pool systems in mountain rivers in enhancing the dissipation rate of large water flowsWe have also examined the relationship between energy dissipation efficiency and flow rate，and evaluated the functionality of artificial step-pool systems in mudslide prevention and riverbed stabilizationThe findings reveal that the energy dissipation efficiency of artificial step-pool systems increases with flow rateMoreover，these systems offer unparalleled advantages in reconstructing near-natural ecosystems and in terms of economic costsBased on the above research results，it is recommended that planning and design units actively adopt artificial cascade-deep pool systems in scenic areas to reconstruct near-natural ecosystems，fundamentally consolidate riverbed control of river valley incision，and achieve the purpose of preventing debris flow disasters |
