中文摘要：

运用ArcGIS9.2软件,从山西植被图中采集各植被类型的每个图斑,将各群系归并到植被、森林、灌丛、草本植被或栽培植被后获取群系的个数和面积,计算群系指标,在SPSS18软件中分析群系指标与其经度、纬度、海拔高度的相关性,探讨植被地带性.用群系的密度、覆盖率和优势度这些指标研究植被、森林、灌丛、草本植被、栽培植被均具有一定的地带性.用群系密度研究植被、灌丛、栽培植被的纬度地带性和垂直地带性与物种多样性的一致,但森林、草本植被的地带性却有些不同.用群系覆盖率研究时,自然植被（森林、灌丛、草本植被）与栽培植被的地带性不同.用群系优势度研究地带性时会受群系的密度或覆盖率的影响.

英文摘要：

Every patch from the vegetation map in Shanxi was edited in ArcGIS software.Formations were divided into vegetation,forest,scrub,herbaceous vegetation and cultivated vegetation,then their number and area were got and indexes were computed.Correlations between formation index and latitude,longitude,altitude were analyzed in SPSS software.Longitudinal zonality,latitudinal zonality and vertical zonality of vegetation,forest,scrub,herbaceous vegetation and cultivated vegetation are studied with formation indexes such as density,coverage rate and dominant rate of formation.There are zones in vegetation,forest,scrub,herbaceous vegetation and cultivated vegetation.Latitudinal zonality and vertical zonality of vegetation,scrub and cultivated vegetation based on density index are consistent with species diversity,but zones of forest and herbaceous vegetation are somewhat different.Zones are different between cultivated vegetation and natural vegetation including forest,scrub and herbaceous vegetation using coverage rate index.Dominant rate is affected by density or coverage rate when zones are studied.
