农作物气候适宜度实时判定系统

以旬、月、季、作物生育期为单位时段,根据农作物生长发育所需要的气象条件,把单位时段内气候因子的数量变化,通过模糊数学中隶属函数的方法,转化成对作物生长发育的适宜程度,计算各时段内的温度、降水、日照及光温水综合因子对作物生育影响的适宜度,计算结果以表格和图形的方式输出。经过业务试应用,效果良好,所计算的不同作物不同时段的温度适宜度、降水适宜度、日照适宜度、光温水综合适宜度符合实际情况,为定量判定气象条件对农作物影响提供了依据。

A Real-Time Analysis System of Crop-Climatic Suitability Based on Fuzzy Mathematics

A real-time analysis system of crop-climatic suitability is introduced.Based on fuzzy mathematics and the necessary meteorological conditions for crop growth and development,the suitability of meteorological factors to crop growth such as air temperature,rainfall and sunshine are computed using the analysis system for different periods of time.The system output adopts grid and graphic formats.It is shown that the analysis results of crop-climatic suitability by the system for different crops and time periods are consistent with the real conditions,and also it gives a quantitative analysis for agricultural meteorological operational service.
