EVALUATION OF MULTI-FUNCTIONALITY OF AGRICULTURE BASED ON MULTI-DIMENSION EVALUATION MODEL
提出一个多维评价模型，利用因子分析和层次聚类法，评估中国农业的生产、经济和生态功能，为政策制定者提供参考。
The idea of multi-functionality of agriculture provides a framework for identifying and evaluating all-around functions of agriculture.A multi-dimensional evaluation model for assessing the multi-functionality of agriculture is proposed to image the variety of roles that agriculture play,by taking the independent and conflicting relationship among them into account.Considering the availability of data,evaluating methodology and principle for indicator selection,productive,economic and ecological roles of Chinese agriculture are evaluated,in which principal components are extracted as influential factors with Factor Analysis Method,and nine scenarios are clustered with Hierarchical Cluster Method according to the components scores.The research shows that multi-dimension evaluation model can make full use of existing statistical data to evaluate three most important functions of Chinese agriculture,with simulation results corresponding to the actual situation very well.The model is flexible enough to be used in multi-objective evaluation in different spatial scales for other disciplines.
