Abstract: Using meteorological data and data of the development period of crisp pears in Ningling county, taking the climate suitability divisions that affect the quality of crisp pears, the meteorological conditions for annual crisp pear growth, and the meteorological disasters during the growing period as the main evaluation indicators, a comprehensive analysis and evaluation were carried out and weighted scores were given, and a climate quality suitability evaluation scoring algorithm was established. Statistical analysis was performed on the climatic resources and main meteorological disasters of various growth periods of crisp pear in Henan province Ningling county demonstration park in 2017, and score calculation was performed. The results show that the climate resources during the key growth period of this year can meet the growth of fruit trees and fruits. There are sufficient light and heat resources, sufficient precipitation during the young fruit period and fruit expansion period, and the main meteorological disasters are high temperature heat damage and drought in midsummer. The final score was 94.5 points, and the climate quality of the crisp pears in this area was considered to be excellent that year.
