模糊聚类分析方法在乌兰察布市林业区划中的应用

根据内蒙古乌兰察布市的自然、社会和经济条件,选取了平均海拔、年均降水、平均温度、农民人均收入、森林覆盖率、天然林面积比重、生态公益林面积比重7个指标,运用模糊聚类分析方法对该区进行聚类区划,区划出5个区域,分别是:Ⅰ阴山山地南麓东段经济用材林区,Ⅱ阴山南麓黄土丘陵防护林区,Ⅲ乌兰布市阴山北麓防护特用林区,Ⅳ乌兰察布市前山丘陵用材林区,Ⅴ阴山山脉灰腾梁南麓特用林区。各区域间自然条件等差异较大,而区内基本相同。针对各区特点提出了林业发展布局、目标及建议。

Application of Fuzzy Clustering Analysis Method in Forestry Division

Based on the natural,social and economic conditions of Wulanchabu City,seven indexes are selected,which are average elevation.average annual rainfall,average temperature,forest coverage,natural forest area,per capita income of farmers and ecological forest area.The fuzzy clustering analysis method is used for the whole area,which is divided into 5 sub-areas by using clustering method.The five sub-areas include timber forest at the south foot of Yinshan mountains,protective forest in the loess hilly area at the south foot of Yinshan mountains,special purpose forest at the north foot of Yinshar mountains,timber forest in the Qianshan hilly area of Wulanchabu city and special purpose forest in Huitengliang area of Yinshan mountains.Big differences exist in natural conditions among those areas,but no difference within each individual area.According to the specific conditions of each area,some strategies,targets and suggestions for forestry development are put forward in this paper.
