Abstract: | Summary Phenological maps of flowering provide useful information about both spatial and temporal patterns of pollen emission, and
their use could bring a substantial improvement of aerobiological forecasts. This paper presents a method for preparing flowering
maps by computer on the basis of phenological data and topography. Data drawn from topographic maps are processed with the
aid of an empirical model, based on the relationships between phenology and environment, for obtaining a phenological delay
matrix. From this matrix it is possible to derive automatically various kinds of maps (chronological, synoptical and differential).
An application is described, relating to the blooming patterns of a set of wild plants in a mountainous area of Northern Italy. |
