摘　　要：针对新疆典型资源型城市土地利用演变对景观格局与生态系统服务价值影响这一关键问题,研究基于解译克拉玛依市1995—2021年4期遥感影像数据,分析土地利用动态演变,测算景观格局与生态系统服务价值变化并计量二者关联度。结果表明:1)克拉玛依市1995—2021年各土地利用类型面积变化呈五增一减趋势,其中草地、耕地、林地、建设用地及水域面积增加,未利用地面积减少。2)研究期内克拉玛依市景观层次景观破碎度呈增长状态,景观分布格局由紧凑向离散变化,景观类型趋于多样化;类型层次各土地利用类型景观格局指数演变具有一定相似性与差异性。3)1995—2021年克拉玛依市生态系统服务总价值呈上升趋势,由14.6251亿元增长至42.2067亿元,共增加27.5816亿元,增幅188.59%,其中水域和耕地为主要贡献者,2021年二者贡献率分别为53.42%、26.32%。4)景观层次景观指数与生态系统服务总价值关联度均高于0.5水平,二者相互作用紧密;类型层次各土地利用类型景观指数与生态系统服务价值关联度具有一定程度一致性与差异性。研究结果为新疆典型资源型城市优化土地利用及生态安全提供科学依据与数据参考。Aiming at the key problem of the influence of land use evolution on landscape pattern and ecosystem service value in typical resource-based cities in Xinjiang.Based on the interpretation of four remote sensing image data of Karamay City from 1995 to 2021,this study analyzed the dynamic evolution of land use,calculated the changes of landscape pattern and ecosystem service value,and measured the correlation between them.Results showed:1)From 1995 to 2021,the area of various types in Karamay showed a trend of five increase and one decrease,among which the area of grassland,cultivated land,forest land,construction land and water area increased,and the area of unused land decreased.2)During the study period,the landscape fragmentation of landscape level in Karamay City showed an increasing state,the landscape distribution pattern changed from compact to discrete,and the landscape types tended to be diversified.There are certain similarities and differences in the evolution of landscape pattern index at the type level.3)From 1995 to 2021,the total value of ecosystem services in Karamay City showed an upward trend,from 1.46251 billion yuan to 4.22067 billion yuan,with a total increase of 27.5816 billion yuan,an increase of 188.59%.Waters and cultivated land were the main contributors,and the contribution rates of the two in 2021 were 53.42%and 26.32%,respectively.4)The correlation degree between landscape level landscape index and total value of ecosystem services is higher than 0.5,and the two interact closely.There is a certain degree of consistency and difference between the landscape index and the correlation degree of ecosystem service value at the type level.The research results provide scientific basis and data reference for optimizing land use and ecological security in typical resource-based cities in Xinjiang.
