Impact of land use change on ecosystem service value in Urumqi
The coordinated development of urbanization and ecosystem is a crucial prerequisite for achieving regional sustainable development.Based on the land use data of 2000,2010 and 2020,combined with ESV equivalent factor and spatial autocorrelation methods,the impact of land use on ecosystem service value in Urumqi under the background of rapid urbanization were explored.The results showed that:(1)Grassland emerges as the most significant land use type in Urumqi.With the exception of construction land and unused land,which exhibit singular dynamic degrees,other types of land display varying degrees of negative growth.(2)The overall trend indicated a decline in total ESV value in Urumqi from 2000 to 2020,with a cumulative decrease amounting to 3.705 billion yuan.In terms of spatial distribution,ESV showed significant spatial differentiation,which was high in the south,low in the north and low in the east.(3)ESV demonstrated strong spatial correlation with adjacent grids.High-high clustering areas were primarily concentrated within Urumqi and along Chaiwopu-Dabancheng District's north-south axis,whereas low-low clustering areas mainly concentrate in Urumqi's northern,eastern regions as well as its main urban area.
