摘要：卡拉麦里国家公园是连接天山和阿尔泰山的重要生态廊道,阻止古尔班通古特沙漠东扩的重要生态屏障,其生态质量对区域环境安全至关重要。采用2000—2023年的MODIS遥感影像,结合气象、地形、土地利用数据,运用ArcGIS 10.2和ENVI软件平台,探究该地区植被生态环境质量的时空演变规律,识别生态修复的关键区域和优先顺序,为国家公园的生态管理和可持续发展提供科学依据。结果表明:(1)总体来看2000—2023年,卡拉麦里国家公园的植被综合生态质量整体偏低,2017年达到最大值,2022年衰减为最低值;(2)从空间视角来看,植被综合生态质量(EQI)的空间分布呈现“西高东低”格局,西北部生态质量逐年下降,而东部和西南部逐年上升;(3)EQI年内变化在5月达到峰值,9月降至最低。年际变化中2007年表现最佳,2022年最差,凸显持续增湿措施在提升生态环境质量中的关键作用。(4)综合植被综合生态环境质量水平和空间格局,识别发现西北部和西南部为生态修复优先区域,东部为生态修复后续区域。可见,将植被综合生态质量指数加入修复关键区识别模型,能够为卡拉麦里国家公园制定保护区空间生态修复规划、系统开展区域生态修复工程提供理论依据,并为相似生态系统保护区的生态评估和修复工作提供参考。
The Kalamaili National Park serves as a critical ecological corridor connecting the Tianshan and Altai Mountains and an essential ecological barrier preventing the eastward expansion of the Gurbantünggüt Desert.Its ecological quality is vital for regional environmental security.This study utilized MODIS remote sensing imagery from 2000 to 2023,combined with meteorological,topographical,and land use data,and employed the ArcGIS 10.2 and ENVI software platforms to explore the spatiotemporal evolution of vegetation ecological quality in the region.The study also identified key areas and priorities for ecological restoration,providing a scientific basis for the ecological management and sustainable development of the national park.The results indicated that:(1)Overall,from 2000 to 2023,the comprehensive vegetation ecological quality of Kalamaili National Park was relatively low,reaching its maximum value in 2017 and declining to its lowest value in 2022;(2)From a spatial perspective,the spatial distribution of the comprehensive vegetation ecological quality(EQI)exhibited a“higher in the west,lower in the east”pattern.The ecological quality in the northwestern region decreased year by year,while it increased in the eastern and southwestern regions;(3)The monthly variation of the comprehensive vegetation ecological quality(EQI)peaked in May and dropped to its lowest in September.In terms of interannual variation,2007 showed the best performance,while 2022 was the worst,highlighting the critical role of continuous humidification measures in improving ecological quality;(4)Based on the level and spatial pattern of the comprehensive vegetation ecological quality,the northwestern and southwestern regions were identified as priority areas for ecological restoration,while the eastern region was identified as a non-priority area.The study suggests that future research should integrate more ground-based measurements and high-resolution remote sensing data to improve assessment accuracy and better assist management departments in formulating and implementing ecological protection and restoration strategies.
