Abstract：Based on Maslow's hierarchy of needs theory, a Happy River evaluation index system involving six levels: healthy river, safe river, enriching people's river, harmonious river, cultural river and livable river was established. Combined with unascertained measurement model and obstacle diagnosis model, Gansu section, Ningxia section and Inner Mongolia section of Yellow River were taken as examples to analyze the construction performance of Happy River from 2015 to 2019 and diagnose the obstacle factors hindering its construction. The Happy River grade index of Gansu province increased from grade IV (unhappy) in 2015to grade II (happy) and the performance index increased from 2.565 in 2015 to 3.471 in 2019. The hierarchy obstacle degree of safe river presented an increasing trend with annual growth rate of 10.94%, while other hierarchy obstacle degrees showed a decreasing trend. Therefore, increasing vegetation coverage rate and soil erosion control ratio should be focused on in the future’s construction. The Happy River grade index of Ningxia region increased from grade III (general) in 2015 to grade II (happiness) and the performance index increased from 2.558 in 2015 to 3.302 in 2019. The hierarchy obstacle degrees of healthy river, livable river and safe river showed an increasing trend with an annual growth rate of 7.29%, 3.60% and 1.98%, respectively. The mean hierarchy obstacle degree of livable river reached 26.870%, which was the biggest obstacle factor restricting the construction of Happy River in Ningxia. As a result, increasing per capita water resources and reducing water consumption of ten thousand yuan of GDP should be focused on in the future’s construction. The Happy River grade index of Inner Mongolia section increased from grade III (general) in 2015to grade II (happiness) and the performance index increased from 2.782in 2015 to 3.387 in 2019. The hierarchy obstacle degrees of livable river, healthy river and safe river showed an increasing trend with the average annual growth rate of 8.93%, 3.91% and 3.71%, respectively. The mean hierarchy obstacle degree of livable river reached 28.90%, which was the biggest obstacle factor restricting the construction of Happy River in Inner Mongolia. Thus, it is necessary to reduce the water consumption of ten thousand yuan of industrial added value and increase the proportion of soil erosion treatment.
