气候生态适宜性隶属度函数

(1) 温度的隶属度函数:

      

式中,μ(T)为温度的隶属度函数;T为实际的温度值;为生长得最低温度;为生长的最高温度;分别表示最适温度的上、下限;b是常数,根据作物生长发育特点、当地气候特点,通过模拟和确定隶属度函数的参数,并通过模拟得到反馈后再行修改、确定。

(2) 日照时数的隶属度函数:

  

式中,S为实际日照时数;S0为日照百分率为70%的日照时数,b为常数。

(3) 降水量隶属度函数:

   

式中,μ(T)为水稻的隶属度函数;A为实际值,ab均为常数,分别为0.50.2166

(4) 旱作物干燥度隶属度函数方程为:

    

式中,b1b2均为常数,分别为0.9,1.1,0.2166,0.3792A为干燥度。
