摘要
[研究目的]人类活动引起的土地利用/覆被变化是全球环境变化的重要组成部分,旱区土地利用对区域水文和生态的影响尤为显著,探究土地利用变化及其对人类活动的响应对西北干旱内陆生态与资源环境可持续发展具有重要意义。[研究方法]基于1980-2018年间共5期遥感影像,结合土地利用动态度、土地利用转移矩阵和人类活动强度指数分析塔里木河流域各水资源分区土地利用变化特征。[研究结果]近40年中,塔里木河流域耕地、建设用地和林地面积分别增加1.58×10^(4)km^(2)、1.2×10^(3) km^(2)和347 km^(2),而草地、未利用地和水域面积分别减少1.33×10^(4)km^(2)、0.32×10^(4)km^(2)和815 km^(2)。各水资源分区中塔里木河干流土地利用类型变化最大,其次为渭干河、阿克苏河和喀什噶尔河流域。自2000年以来,塔里木河流域建设用地当量面积和人类活动强度增加相对较快,特别是2000-2010年间呈显著增长趋势。[结论]塔里木河流域各水资源分区的人类活动强度呈显著的空间差异性。社会经济发展和政策的导向性作用是塔里木河流域土地利用变化和人类活动强度的主要影响因素。
[Objective]Land Use/Cover Change(LUCC)caused by human activities is a critical part of global environmental change.LUCC in arid regions has a particularly significant impact on regional hydrology and ecology.Therefore,exploring LUCC and its response to human activities is of great significance to the sustainable development of ecology,resources and environment in the arid inland of Northwest China.[Methods]Based on the Landsat images during 1980 to 2018,this paper analyzes the characteristics of land use change in nine divisions of water resources of Tarim River Basin,by the combination of land use dynamic degree,land use transfer matrix and human activity intensity degree.[Results]In the past 40 years,cropland,constructive land and forest increased by 1.58×10^(4)km^(2),1.2×10^(3)km^(2) and 347 km^(2),respectively.By comparison,grassland,unutilized land,water and wetland decreased by 1.33×10^(4)km^(2),0.32×10^(4)km^(2) and 815 km2,respectively.The main stream of Tarim River Basin has experienced the most significant change in land use types among nine divisions of water resources,followed by Weigan,Aksu and Kashgar river basin.Since 2000,the equivalent area of constructive land and human activity intensity in Tarim River Basin has increased relatively fast,especially from 2000 to 2010.[Conclusions]Human activity intensity has showed significant spatial difference among division of water resources.Socio-economic development and policy guidance are major factors leading to land use change and human activity intensity difference.
