摘要: 以森林资源二类调查、SPOT5遥感影像为基础数据,在景观生态学原理和GIS技术支撑下,从景观类型指标(斑块数量、斑块密度、最大斑块指数等)和景观水平指标(景观丰度、多样性、蔓延度等)两个层面对研究区土地利用空间格局进行定量分析,并运用VCM曲线深入探讨了主要景观类型的聚集程度。研究结果表明:2010年云岭自然保护区土地利用多样性程度低,且分配不均;有林地是整个保护区生态系统中的优势组分,内部斑块大、不破碎;耕地面积仅次于有林地,破碎程度最高;受人为活动干扰最明显的是灌木林地;研究区中,除水域外的其它各景观类型聚集程度高,一旦发生蔓延事件,传播速度快。

Abstract: In order to manage the nature reserve resource more effectively,this paper has used the landscape ecology principle and GIS technology to quantitatively analyze landscape spatial patterns in the study area based on the forest resources survey and SPOT5 remote sensing image.Landscape class index(such as number of patches,density of patches,largest patch index,etc.)and landscape index(such as patch density,Diversity,contagion,etc.)are two kinds of research directions,then the VCM curve has been used for further exploration and study of the aggregation degree of main landscape types.The results show that the study area’s land use diversity was low in 2010,and all landscape components are unevenly distributed. The advantage component is forest land;the highest fragmentation degree is farmland with the area close to forest land;shrub land is easy to suffer interference.Except for water area,other landscape types have high aggregation degree. Once a spreading event happens,it will develop very fast.

Key words: landscape pattern, VCM curve, nature reserve management
