- 摘要:
- 以陕西米仓山自然保护区植被图为基础，利用GIS软件将其数字化，并提取各植被景观斑块信息，从植被景观斑块的数量、面积和周长等方面对陕西米仓山自然保护区的植被景观及破碎化程度进行分析。结果表明：落叶阔叶林、针阔叶混交林和落叶阔叶灌丛是该保护区的3个主要景观类型；植被景观斑块数量、面积和周长的分布差异较大；落叶阔叶林、针阔叶混交林和人工林景观的破碎化程度较低，而暖性针叶林、农田、撂荒地和灌草丛景观的破碎化程度较高。
- Abstract:
- Based on the vegetation maP of Micang Mountain Nature Reserve in Shananxi Province,with the helP of GIS software to get the information of the vegetation landscaPe Patch,the vegetation landscaPe Pattern and fragmentation from Patch area,Perimeter and number characteristics in Shananxi Micang Mountain Nature Reserve were analyzed.The results showed that deciduous broadleaved forest,coniferus-broadleaved mixed forest and deciduous broadleaved shrub were three main comPonents in Shananxi Micang Mountain Nature Reserve.The distribution difference of area,Perimeter and the number of Patches of different landscaPe elements were significant.The degrees of fragmentation of deciduous broadleaved forest,coniferus-broadleaved mixed forest and artificial forest were lower,and the degrees of fragmentation of warm coniferous forest,farmland,abandoned land and shrub and grass were higher.
