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。
Based on the second type of forest resources survey and SPOT5 remote sensing image data, under the support of landscape ecology principles and GIS technology, the landscape type indicators (number of patches, patch density, maximum patch index, etc.) and landscape level indicators Abundance, diversity, degree of spread, etc.) to quantitatively analyze the spatial pattern of land use in the study area. The degree of aggregation of the main landscape types is also discussed in depth by using the VCM curve. The results show that in 2010, the diversity of land use in Yunling Nature Reserve is low and unevenly distributed. The forest land is the dominant component of the ecosystem in the whole reserve. The internal patches are large and not broken. The cultivated area is second only to In the study area, all other landscape types except water area had a high degree of aggregation, and once the spread occurred, the spread speed was fast.
