Study on the Impact of Years of Climate Change on Ecological Structure in the Jiuquan Area of Qilian Mountain National Park
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.
