摘要
应用系统论的观点建立了跋山库区土地生态系统模型,并对系统多因子进行了定量分析。在定量评价的数学模型中,应用Q型系统聚类分析划分土地生态类型,应用主成分分析法确定各生态类型的地位级指数。
Land ecological model system is set up by using systematic idea, and multi-factors are analysed quantitatively. In mathematical model of quantitative evaluation, land ecological types are divided by using cluster analysis of Q system, and position ratio of all ecological types are determined by using major composition analysis method.
