摘要:
森林保护区景观格局的变化是揭示其生态状况及空间变异特征的有效手段,开展西藏天然林保护区景观格局动态变化的研究对科学认识西藏天然林动态变化规律,维护森林景观稳定性,保障森林生态系统安全具有重大意义。文章对2000年和2010年遥感影像进行监督分类,根据保护区自然特征分析了研究区土地利用状况,选取了11种景观指数对保护区景观格局的动态变化进行了研究,从斑块类型水平和景观水平两方面阐明了其景观异质性变化趋势,提出了景观优化策略。结果表明:天然林保护工程实施后,保护区土地利用类型变化明显,植被覆盖度增加到84.5%,土地类型空间分布存在差异;景观格局斑块个数减少但依旧较多,景观最大斑块指数和平均斑块面积增加;景观异质性降低,破碎度较大;可采取加强荒漠治理、人工管理、建立生态廊道等措施优化景观格局。
Abstract:
The change of forest landscape pattern is an effective means to reveal its ecological status and spatial variability. The study on the dynamic change of landscape pattern of natural forest reserve in Tibet has great significance for scientific understanding of the dynamic change law of natural forest in Tibet, maintaining the stability of forest landscape and ensuring the safety of forest ecosystem. Based on the data of remote sensing images in 2000 and 2010, the paper analyzed the utilization of land in the study area, selected 11 landscape indices to analyze the changes in landscape pattern of the reserve and elucidated the trend of landscape heterogeneity from patch level and landscape level. In view of the problems in the study area, some strategies for optimizing landscape patterns were put forward. The results showed that, after the protection of natural forest, land use of study area changed obviously, the vegetation coverage increased to 84.5%, the land type spatial distribution differences; the number of landscape patches decreased but still more, the largest patch index landscape and the average patch area increased; landscape heterogeneity decreased and fragmentation was greater. The landscape pattern could be optimized by strengthening desert management, artificial management and ecological corridor construction.
