Abstract: Based on the monitoring data of Nanguo pear in the development period and regional meteorological stations,according to the demand of meteorological conditions for the growth and development of Nanguo pear,by using statistical methods,the evaluation indexes of the influence of temperature,light,water and other meteorological factors on Nanguo pear quality were determined. The results showed that:（1） The climate quality evaluation model of Nanguo pear was composed of 14 factors,including regional suitability,meteorological conditions in different phenological periods,meteorological disasters and production management conditions. Among them,the main meteorological factors affecting the quality of Nanguo pear were temperature,precipitation,sunshine,fruit setting period,fruit expansion period and fruit sugar period in each development stage.（2）The climate quality evaluation score of Nanguo pear produced by Tianying Fruit Industry in Wangshi Town,Anshan,Liaoning province in 2018 was 89.6,which was the most“excellent”grade.
