| Abstract: | Meteorological disasters influencing the paddy yield in Yunnan were analyzed. It is indicated that drought in early summer and low temperature in August are the major ones. The former could influence the transplanting time and area. Low termperature in August is the main factor of low yield of rice.Based on numerical modeling analysis with integral regression, the following conclusions were drawn: Air temperature was the primary climatic factor impacting rice yield in Yunnan. The period from the heading stage to milk ripe stage was the key period during which air temperature had the maximum effect on the yield. The influencial region, light and heavy damage region caused by low temperature in August were discussed. |
