Abstract:

Based on the daily meteorological data of 95 meteorological stations in Henan Province from 1961 to 2020, the spatiotemporal variation characteristics of the climate resources and major agrometeorological disasters of facility agriculture were analyzed by using the methods of climate tendency rate and the Matlab and ArcGIS software. The results showed that the average temperature and the average minimum temperature in the growing season of facility agriculture in Henan Province showed a significant increasing trend, while the sunshine hours showed a significant decreasing trend. The spatial distribution showed a zonal distribution. The average temperature and the average minimum temperature increased from north to south, while the sunshine hours decreased from north to south. The number of low temperature stations with the daily average temperature < - 8℃ had a significant decreasing trend, and the number of sunshine days had a significant increasing trend, with the number of snowstorm stations no obvious trend of change. The days of low temperature decreased from north to south, while the days of sparse sunlight increased from north to south, with the spatial distribution of snowstorm days implicit. Arrangements on planning of facility agriculture should be done in Henan Province, because of the diversity of agricultural meteorological disasters.

Key words: Henan Province, facility agriculture, climate resources, meteorological disaster
