METHODS CALCULATING THE SPATIAL DISTRIBUTION OF AGROCLIMATIC RESOURCES IN MOUNTAINOUS AREAS AND CLIMATIC EFFECTS OF MICROTOPOGRAPHY*

PDF

  • The methods calculating the spatial distribution of agroclimatic resources (temperature,humidity,precipitation,wind speed,etc.) in mountainous areas are presented.The linear model can be used for the mean temperature,accumulated temperature,and the occurrence date and duration of limiting temperature,but the nonlinear model for extreme temperature,humidity,precipitation and wind speed.The climatic effects of topography obtained from the application of these methods in the Shaxi River basin,Fujian Province,are also described.The results show that the methods proposed in this paper may effectively disclose the macro-and micro-variations of spatial distribution of agroclimatic resources in mountainous areas.
