Abstract：Focusing on the evaluation of construction effectiveness of happy rivers and lakes in plateau regions,this study takes the happy river and lake in Zhongqu,Ngari,Tibet,as a typical case.It systematically analyzes the applicability and limitations of the mandatory indicators in the current"Work Plan for Evaluating the Effectiveness of Happy Rivers and Lakes Construction(Trial)"under the special conditions of plateau environments.The study identifies eight mandatory indicators that are clearly unsuitable,falling into two categories:those requiring optimization,including flood control compliance rate,soil and water conservation rate,water quality status,and cultural inheritance;and those requiring replacement,including natural shoreline condition,ecological flow satisfaction,total pollutant reduction,and per capita disposable income of residents.Based on the principles of scientific soundness,fairness,quantifiability,and data availability,an optimization and replacement scheme adapted to plateau conditions is proposed,and a revised evaluation system is constructed.A comparative scoring analysis between the original and revised systems shows that the improved system demonstrates higher rationality,better data availability,and stronger operability in plateau environments,leading to more objective and scientific evaluation results.This study not only enhances the applicability and guidance of effectiveness evaluation of happy rivers and lakes construction in plateau regions,but also provides a scientific basis and practical approach for river and lake management and sustainable development in cold and ecologically fragile areas.
