摘　　要：祁连山国家公园位于甘肃省与青海省的交界处,地处青藏高原东北部边缘,自然资源丰富。为了明确祁连山国家公园酒泉片区生态结构变化趋势,结合2006—2021年Landsat卫星影像数据,运用归一化植被指数(Normalized Difference Vegetation Index,NDVI)建立解译样本集,应用eCognition软件与ArcGIS软件人机交互的解译方式,研究冰川与积雪、草地、河流水面、内陆滩涂、裸岩、湖泊水面、沙地和建设用地等地类的变化。同时,结合研究区2006—2021年温度、湿度、降雨量和蒸发量等数据,运用偏最小二乘法建立祁连山国家公园酒泉片区生态结构变化回归模型,结合MATLAB软件定量模拟分析16年间气候变化对区域生态结构的影响,从而更好地推进区域生态文明建设,保护祁连山生物多样性,维护自然生态系统原真性与完整性。The Qilian Mountains National Park is located at the border of Gansu province and Qinghai province,on the northeast edge of the Qinghai-Tibet Plateau,with abundant natural resources.In order to clarify the change trend of ecological structure in Jiuquan area of Qilian Mountain National Park,combined with the Landsat satellite image data from 2006 to 2021,the Normalized Difference Vegetation Index(NDVI)is used to establish the interpretation sample set,and the interpretation method of human-computer interaction between eCognition software and ArcGIS software is used to study the changes of glaciers and snow,grasslands,river water,inland mudflat,bare rocks,lake water,sandy land and construction land.At the same time,based on the temperature,humidity,rainfall,and evaporation data of the research area from 2006 to 2021,a partial least squares regression model for ecological structure changes in the Jiuquan area of Qilian Mountain National Park is established using the method of partial least squares,and MATLAB software is used to quantitatively simulate and analyze the impact of climate change on regional ecological structure over the past 16 years,in order to better promote regional ecological civilization construction,protect Qilian Mountain biodiversity,and maintain the authenticity and integrity of the natural ecosystem.
