Risk Zoning of Inducing Agro-meteorological Disaster Factors in Guizhou
In order to provide reference for optimization adjustment of crop distribution in agriculture,and forecast and prevention of meteorological disaster,hazard of meteorological disaster to agricultural production in Guizhou was relieved,according to inducing agro-meteorological disaster factors and disasterpregnant environment on the basis of risk assessment of main inducing agro-meteorological disaster factors to optimize crops distribution in production.Results:Cold spell in later Spring of high risk areas are mainly distributed in the northwest of high altitude.Autumn wind of high risk areas is in the northwest with a film distribution.Distribution in spring increased gradually from east to west,relatively high risk area mainly consists of Western Guizhou,southwest of Qiannan state,Liupanshui City,Anshun in the southwestern part of the city and Bijie Prefecture.Drought in summer and drought spatial distribution on the contrary,is decreasing gradually from the east to the west and the regularities of distribution of the horizontal strip of continuity and a film distribution characteristic,year round general in the eastern area of Guizhou Province appear piece of drought in summer.The map (100 m × 100 m resolution) with respect to the spatial superposition method or traditional spatial interpolation method has better spatial continuity and accuracy.
