基于景观格局指数的乌鲁木齐市主城区时空动态演变分析

Analysis of Spatial and Temporal Dynamic Evolution of Urumqi based on Landscape Pattern Index

乌鲁木齐市作为“一带一路”的中亚区域经济中心,其城市动态演变对干旱区的可持续发展尤为重要。1990-2020年乌鲁木齐市主城区急剧扩张,主城区扩张加速。运用景观格局指数对乌鲁木齐市主城区土地利用空间格局复杂性与多样性进行分析,发现1990-2020年主城区土地利用类型的各类用地的稳定性与均匀性加强。上述对于乌鲁木齐市主城区的时空动态演变研究,有助于我们审视乌鲁木齐市扩张所造成的景观生态脆弱性表现与隐患,这对其未来的城市扩张具有良好的科学参考价值。

As the regional economic center of Central Asia of "Belt and Road", the dynamic urban dynamic evolution of Urumqi is particularly important for the sustainable development of arid areas.From 1990 to 2020, the main urban area of Urumqi expanded rapidly, and the main urban area expansion accelerated.The complexity and diversity of the spatial pattern of land use in the main urban areas of Urumqi were analyzed, and we found that the stability and uniformity of all types of land use types in the main urban areas from 1990 to 2020 were strengthened.The above research on the spatial and temporal dynamic evolution of the main urban area of Urumqi city will help us to examine the performance and hidden dangers of the landscape ecological vulnerability caused by the expansion of Urumqi city, which has a good scientific reference value for its future urban expansion.
