基于RS-GIS梵净山植被分布规律的研究

Study on distribution of vegetation in Fanjing mountain Based on RS-GIS

随着气候环境的变化,植被类型的分布与其生长环境也受到了严重的影响,以梵净山自然保护区为例,通过GIS空间分析功能定量分析了梵净山自然保护区植被分布情况,并结合相关环境数据对影响梵净山的植被分布进行统计分析,通过分析不同植被类型与气温、降水、海拔、坡度和坡向5个环境因子的关系,结果显示,坡度是影响梵净山植被类型分布格局的主要因素,并得出了梵净山各植被类型的最优发育环境区间,通过揭示植被与环境的相互关系及影响,将有助于梵净山自然保护区的管理与植被保护。

With the developing of world,global climate is changing,and gradually effect on our production and daily life,forests are know as ＂atmospheric oxygen bar＂, how to protect and develop them has become a big problem.Taking Fanjing mountain nature reserve as an example,we got an deeply understand about Fanjing mountains nature reserve of vegetation distribution situation by software GIS,analyzed and counted the related environmental data which would effect on vegetation distribution of Fanjing mountain by the way of combining with the related environmental data,by analyzing and discussing the relationships of five environmental elements,various vegetation types,temperature,precipitation,altitude and slope,can help you get a comprehensive understanding of the structure and function of vegetation distribution,grasp the general characteristics of vegetation distribution of Fanjing mountain nature reserve which is good for revealing the relationship between vegetation and environment and influence.
