大熊猫国家公园阿坝片区生态系统质量时空变化分析
摘要
Abstract
The study area is the Aba area of the Giant Panda National Park.Using GIS as the technical platform,and taking vegetation coverage,leaf area index,and total primary productivity as the evaluation indicators,a method of selecting reference values by region and ecosystem type was adopted to construct the ecosystem quality index.Data from 2010 and 2020 were selected to analyze the ecosystem quality in the study area from both spatial and temporal dimensions.The results show that:The overall ecosystem quality in the Aba area of the Giant Panda National Park shows an improving trend.The average ecosystem quality values for 2010 and 2020 were 63.1 and 66.9,respectively,showing an increase of 3.8.The area where the ecosystem quality has improved accounts for 29.34%of the entire region,while the proportion that has deteriorated accounts for 9.3%,and the proportion that remains largely unchanged accounts for 61.36%.Among them,the highest proportion of conversion was from good to excellent ecosystem levels,reaching 18.95%.Notably,the changes in Wenchuan,Maoxian,and Songpan were more significant.关键词
