| Abstract: | This paper is a study based on the food crop yield data (1949-1990) and corresponding meteorological
data in Zhejiang Province. Some features of meteorological disasters which influence the food crop production
of this province are as follows:
1. The annual change of the duration of meteorological disaster years has a quasi-cycle ; 2. The distribu-
tion of the period of meteorological disaster years is possessed of a continuity; 3. Meteorological disasters
which cause the poor harvest or grievous poor harvest years are possessed of many harvest seasons and many
types; 4. Meteorological disasters which influence the food crop yield of this province may be classified as ap-
parent disasters and not apparent disasters, and have the primary and secondary extent in various years. |
