Abstract: The introduction of the "double reduction" policy provides policy support and practical direction for deepening the reform of the elementary education in Qujing, building a good education ecosystem, and achieving development of quality. The high-quality elementary education ecology cannot be separated from the internal integration and orderly cooperation of the three ecological circles: the main ecosystem, the normative ecosystem, and the social ecosystem. In the past decade of the new era, while the elementary education ecology in Qujing has shown a good development momentum, there are also some problems such as obvious exam oriented concepts, imbalanced urban-rural education, disordered private education, inconsistent structural layout, and single evaluation methods. The high-quality development of elementary education in Qujing requires the use of "double reduction" and multi-party efforts to reconstruct the basic education ecosystem. At the normative level, the improvement of the institutional system of pluralistic co-governance should be realized; at the subjective level, a harmonious and progressive teacher-student relationship should be established; and at the social level, the synergy of internal and external education should be enhanced.

Key words: elementary education ecology, double reduction, development dilemma, high quality, Qujing
