| 摘 要： | 通过景观的观点来审视城镇化的发展,是解决城市化过程中环境问题的新方法、新思路.采用2009年广西壮族自治区贺州市八步区仁义镇森林资源二类调查数据为基础数据,以GIS和Fragstats为技术支撑,从景观的组成结构、斑块特征等方面对研究区域景观的空间分布和结构特征进行了分析.结果表明,景观要素斑块中以小斑块所占比例最大,植被景观以乔木林和灌丛景观为主要类型.由于相对强烈的人类活动影响,区域内林业用地的景观破碎化程度较高.

| Abstract: | A new way of solving environmental problems in the urbanization process is using the landscape perspective to view the development of urbanization.In this study,the Forest Resource Inventory Data of Renyi Town,Babu District,Hezhou City in Guangxi in 2009 are used as basic data,GIS and Fragstats are used for the technical support,this paper analyzed the spatial distribution and structural features of regional landscape from the landscape composition and patch characteristics.The result shows that the small plaques are the largest proportion in landscape elements of patches,and the major type of vegetation landscape are arbor forest and shrubbery landscape.The landscape pattern analysis of forest land shows that the forest land of this region have a higher degree of landscape fragmentation due to a relatively strong impact of human activities. |
