摘要
通过综合运用主成分分析和层次分析方法,建立系统综合评价的AHP变量加权主成分分析模型.在构建青藏高原牧区可持续发展评价指标体系的基础上,基于该模型方法对青海省内的30个牧区县给出发展现状的评价实例.最后,讨论了模型方法使用中的若干改进方法思路,以提高评价稳定性和效果.
Using the methods of Principal Component Analysis (PCA) and the Analytical Hierarchy Process(AHP), the paper proposes the synthetic evaluating model of PCA with weighted variables by AHP. Establishing evaluation indicators system of sustainable development for pastoral areas on Qinghai-Tibetan Plateau, the authors also give the evaluating example of 30 counties in Qinghai based on this model, in which we make quantitative evaluation and qualitative analysis of sustainable development status for those counties. Furthermore,the paper discusses some refinement measure in order to improve stability and effectiveness for this model in application.
