Abstract: Based on field experiment and corresponding meteorological data, and by using GIS and climatic elementscomputing model, this paper studied the biological performance and suitable planting areas of unseasonable strawberry in Fuping mountainous region of Hebei Province. The results showed that in study region, strawberry could over-winter, blossom and seed. Its growth period was lagged behind of that in Hebei Plain, and thus, could mature unseasonably. The quality of unseasonable strawberry was excellent, with higher soluble solid and vitamin C contents than those planted in Hebei Plain. The suitable planting areas of unseasonable strawberry in Fuping mountainous region were at the altitudes of 900-1200 m.
