摘　　要：沙漠化防治是生态文明建设的重要工作,利用遥感技术为经济发展与环境治理提供支撑服务具有重要的生态和经济价值。本文利用基于MODIS的NDVI数据产品对内蒙古自治区乌兰布和沙漠养牛模式进行了研究,分析了沙漠奶牛产业发展,探讨了2005—2021年磴口县奶牛存栏量变化。研究发现,随着沙漠养牛产业发展,当地植被覆盖度从2005年的21.85%提升到2021年的37.31%,奶牛产业占GDP比例从2005年的12.37%上升至2021年的39.41%。进一步的相关性分析显示,存栏奶牛数量和植被覆盖的相关性系数为0.88,说明奶牛数量和当地植被覆盖具有强关联;存栏奶牛数量和GDP相关性系数为0.69,说明奶牛数量和当地GDP具有较强关联。综合看,沙漠养牛对改善当地生态环境和促进经济增长具有明显的效果。Desertification control is a key task in ecological civiliaztion construction,which uses remote sensing technology to provide support and services for economic development and environmental governance and it is of great economic and ecological significance.Using NDVI based on MODIS,this paper studies the desert dairy cow farming model carried out in Ulan Buh Desert of Inner Mongolia Autonomous Region,analyzes the development of dairy cow farming industry,and discusses the change of breeding stock of dairy cows in this area from 2005 to 2021.The study shows that with the development of dairy cow farming industry,the local vegetation coverage has changed significantly,increasing from 21.85% in 2005 to 37.31% in 2021.Combined with the analysis of the local GDP,it is found that the proportion of dairy industry in GDP has increased from 12.37% in 2005 to 39.41% in 2021,showing that desert dairy cow farming has driven the development of local GDP.Further correlation analysis shows that the correlation coefficient between the number of dairy cows and vegetation fractional coverage is 0.88,indicating a strong correlation between the two;the correlation coefficient between the number of dairy cows and local GDP is 0.69,indicating a relatively strong correlation between the number of dairy cows and local GDP.On the whole,desert dairy cow farming has an obvious effect on improving the local ecological environment and promoting economic growth.
