以３０ａ的气象资料和８种作物生长发育特性为基础，运用模糊数学的隶属函数原理分析中国红黄壤地区作物生长的气候生态适应性。研究结果表明，春播作物全生育期温、光、降水适应性隶属度分别呈低、高、低，低、一般、高，高、一般、低的形式；夏播作物分别呈低、高、低，高、一般、低，低、低、低的形式；秋播作物分别呈一般、高、低、高，高、低、低，低、较高、一般的形式。提出了优化管理的对策。

On the basis of the meteorologic data in 30 years and the growing and developing character of 8 crops, the climatic ecology adaptability of the crop production in the red and yellow soils region of China is analyzed with the principle of subordinative function of fuzzy mathematics. The results show that the adaptability─subordinative values of temperature, sunshine and rainfall for the spring─sowing crops in the whole growing and developing periods are low, high, low; low, medium, high; and high, medium, low respectively. Those for the summer─sowing crops are low, high, low: high, medium, low; and low, low, low respectively.Those for the autumn─sowing crops are medium, high, low, high; high, low, low; and low,high, medium respectively. The optimal management countermeasure is suggested.
