摘  要:
在综合分析香格里拉县林业发展区划的主要影响因素的基础上,建立了香格里拉县林业发展区划指标体系;利用主成分分析方法建立了综合模型,确定了全县的林业分区数量及各分区的林业发展方向;同时,利用判别分析方法对区划结果进行了检验。结果表明,基于综合建模的区划方法对于各分区划分得较为准确,能够将具有相对优势的区域合理分开,总体上各分区划分得较为合理。

摘  要:
Based on the research in Shangrila County,Yunnan province of China,the major factors of forestry division in Shangrila were extracted,and the indicator system of Shangrila forestry division was established.The indicators were extracted with the spatial analysis,and the forestry division method of integrated modeling was processed.The method was taken through Principal Components Analysis,building the integrated model,Discriminate Analysis,seeking the ideal number of divisions and eliminating the scrappy polygons.The outcome showed that the method can reflect the present situation of the forestry development.The relative dominant subdivisions were distinguished reasonably,and a specific direction in forestry development was given.According to the statistics of the subdivisions,the relative dominant subdivisions were showed obviously.
