基于RS、GIS的天目山自然保护区植被空间分布规律研究

Spatial distribution of vegetation in Tianmu Mountain Nature Reserve based on RS and GIS data

以RS、GIS技术为工具 ,将天目山自然保护区的TM遥感影像进行处理与分类得到该区的植被分布图。利用GIS空间分析功能 ,研究了天目山自然保护区内各植被类型空间分布规律 ,重点研究了其中的一种植被类型。研究结果定量描述了自然保护区内各植被类型的高程、坡向、坡度分布 ,给出科学的统计结果。总结了研究区内植被类型的空间分布规律 ,把对植被类型的空间分布规律的定性理解转为定量描述 ,结合实际给出了理论解释。为自然保护区的规划、管理和保护提供了科学依据。

The paper discussed the spatial distribution of vegetation in Tianmu Mountain Nature Reserve. RS and GIS method provided a macans investigating the relationship between the dominant topographic factors (elevation,aspect,and slope ) and the distribution of vegetation. The result quantitatively expressed the spatial distribution of vegetation in the study area. Some distribution paterns were concluded and explained. The study provided useful information for the management of Tianmu Mountain Nature Reserve.
