西藏天然林保护区景观格局分析
Analysis of landscape pattern of forest protection area in Tibet
摘要
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 1 1 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.关键词
