Abstract: The climate impact assessment of rice quality refers to the quantitative assessment of the impact of climatic conditions on rice quality. The traditional technical methods mainly rely on the harvest and planting experience to evaluate and certify the growth of rice. This study took the fragrant rice yellow hair stick, which is a characteristic of Hubei Xiangrun Ecological Agricultural Cooperative as an example, and used the observation data of the Xiaogan National Reference Climate Station （hereinafter referred to as Xiaogan Station） and Dougang Regional Station （hereinafter referred to as Dougang Station） around the region to construct a yellow hair climatic evaluation model for sticky quality was developed and quantitative evaluation was carried out. The research showed that in the past 10 years （2010—2019）, the yellow hair sticky quality has been excellent for 4 years, and the quality was good for 6 years, the whole milled rice rate reached the first grade, the alkali consumption value was the first grade, the glue consistency was the third grade, and the transparency was the second grade. The comprehensive evaluation of the 2020 yellow hair sticky climate quality grade was excellent. The evaluation results were basically consistent with the agricultural obscruation recorcls.

Key words: Xiaogan city, fragrant rice, climate quality, quantitative evaluation
