摘要
确定了植物区系6个基本特征的数量描述与处理方法;应用模糊数学中综合评判的方法建立了植物区系基本特征的参数综合表达式。最后通过实例验证,其参数综合表达式计算出来的结果与实际情况一致。
In this paper the methods of quantitative description and treatment of six kinds fundamental characteristics of flora was establishedas follows:1. Floristic abundance A_(iq)=n_(iq)/M_q (1)2. Floristic resemblance R_(iq)=a(iq)/M_q (2)3. Floristic acientness O_(iq)=(n_(iqu)/n_(iq))/(m_(qu)/M_q) (3)4. Floristic growth of speciation S_(iq)=(n_(iq)-1/n_(iq))/(M_q-1/M_q) (4)5. Complex of floristic elements F_(iqp)=(n_(iqp)/n_(iq))/(M_(qp)/M_q) (5)6. Endemicity of floristie elements E_(iq)=(e_(iq)/n_(iq)/(e_q/M_q) (6)Secondary, the fuzzy mathematical methods of comprehensive judgement which had been used for the integrative comparison and evaluation of six kinds quantitative targets on the fundamental characteristics of flora was introduced. The integrative expressive formula of parameter on the fundamental characteristics of flora was established as follows:d_i=f(d_(1i), d_(2i), d_(3i)) (i≤t) (7)Last, based on the analysising of the spermatophyte floristic fundamental characteristics of 3 single flora, the applied circumstance of the integrative expressive formula of parameter on the fundamental characteristics of flora was discussed. The results was in correspondence with the paracticable circumstances.
