苹果园综合评价的数学模型及应用

通过对山东省主要果产区成龄小国光苹果园的抽样调查，应用系统工程、多元统计分析及试验设计等方法，寻求苹果园高产优质的树体结构、农技措施、土壤营养及其优化组合方案；借鉴苹果树稳产高产的其它研究，对果园管理水平各因素进行科学的等级，应用专业知识建立各因素的隶属函数，通过二元对比排序研究权重向是值，实现对苹果园的多级模糊层次综合评价。

A MATHEMATICAL MODEL FOR COMPREHENSIVE EVALUATION OF APPLE ORCHARD AND ITS APPLICATION

On the basis of investigating bearing apple orchards of Ralls in the main fruit production areas within Shandong Province, using methods of multivariate statistical analysis,system enginerring and experimental design to seek for an optimal scheme of population structure, soil nutrition and agrotechnical measures of orchards with high yield and good quality. The other positive result of high yield and good quality was used as an example for making a scientific classification of every factor at the management level. The sub-functions were structured for every factor according to the speciality of the apple. The weight vector was calculated by binary contrast sequencing. Finally, a mathematical model of comprehensive evaluation of bearing apple orchards was established and the comprehensive evaluation was realized.
