2003年~2020年吉林省长春市植被覆盖变化特征监测
Vegetation Cover Change and Its Causes in Changchun, Jilin Province from 2003 to 2020
摘要: 植被资源对于人类的生产生活和生存发展具有至关重要的意义，本论文以吉林省长春市03、13、20年的Landsat ETM/OLI遥感影像作为基础数据源，利用ENVI软件，对03~20年间的长春市影像进行预处理和解译等工作，之后通过土地类型分类和NDVI的方法，表达出03~20年间土地类型的变化，重点关注土地类型中植被的变化情况。同时应用ArcGIS软件特有的空间分析功能，得到例如植被面积变化、植被变化速率、植被变化特征等植被信息。最后根据相应网站或文献，取得有关长春市对应时期的可能影响植被变化的相关数据，探讨其植被变化特征和内在动因。
Abstract: Vegetation resources are of vital significance to human production and life, survival and development. In this paper, Landsat ETM/OLI remote sensing images of Changchun in 2003, 2013 and 20 years in Jilin Province are taken as the basic data source, and ENVI software is used to preprocess and interpret the images of Changchun in 2003~20 years. Then, the changes of land types during 2003~20 were expressed by land type classification and NDVI method, focusing on the changes of vegetation in land types. At the same time, the special spatial analysis function of ArcGIS software is used to obtain vegetation information, such as vegetation area change, vegetation change rate, vegetation change characteristics and so on. Finally, according to the corresponding website or literature, the relevant data about the possible impact of vegetation change in Changchun City in the corresponding period are obtained, and the characteristics and internal causes of vegetation change are discussed.
