Remote sensing imagery is the data source studied in this article, and it is an important basis for obtaining surface information and other factors. The TM/ETM remote sensing images provided by the United States Landsat (Landsat-5, 7) have become an important remote sensing data source for earth resources and the environment widely used in various countries around the world. It has high spatial resolution, spectral resolution, extremely rich information and high positioning accuracy. This kind of remote sensing data source has been widely used in the extraction of various thematic information such as land use/cover dynamic monitoring, vegetation parameter inversion, environmental pollution and disaster monitoring. The purpose of this research is to analyze the ecological environmental impact of the development of mineral resources in the study area. Taking into account the research content and the specific conditions of the watershed, TM images can meet the needs of the research, so this study chooses TM images as the basis of remote sensing data. When selecting remote sensing data, try to select high-quality images with high definition, relatively rich tones, and less clouds and snow as much as possible. The quality of remote sensing data directly affects the interpretation accuracy of land use/land cover information in the study area and the extraction accuracy of environmental factors such as vegetation coverage and soil erosion. This research analyzes the impact of mineral resource development on the ecological environment. The information on these environmental factors is the data basis for the research and plays a key role in the research results. Therefore, it is very important to choose high-quality remote sensing images.

Remote sensing image is the data source of this paper, and it is an important basis for obtaining surface information and other factors. The TM/ETM remote sensing image provided by Landsat-5 and 7 has become an important data source for remote sensing of Earth resources and environment widely used in all countries of the world. It has high spatial resolution, spectral resolution, abundant information and high positioning accuracy. This remote sensing data source has been widely used in the extraction of land use/cover dynamic monitoring, vegetation parameter inversion, environmental pollution and disaster monitoring and other thematic information extraction. The purpose of this study is to analyze the ecological environment impact of mineral resources development in the research area. Considering the research content and the specific situation of the basin, TM image can meet the needs of the research, so the TM image is used as the basis of remote sensing data in this study. When selecting remote sensing data, high-quality images with higher clarity, relatively rich hues, less clouds and less snow are selected. The quality of remote sensing data directly affects the interpretation accuracy of land use/land cover information in the study area and the accuracy of the extraction of environmental factors such as vegetation cover and soil erosion. This study analyzes the impact of mineral resources development on the ecological environment, and these environmental factor information is the data basis of the research and plays a key role in the research results. Therefore, it is very important to choose high-quality remote sensing images.

This kind of remote sensing data source has been widely used in land use / cover dynamic monitoring, vegetation parameter inversion, environmental pollution and disaster monitoring and other thematic information extraction. The purpose of this study is to analyze the eco-environmental impact of mineral resources development in the study area. Considering the research content and the specific situation of the basin, TM image can meet the needs of the research, so this study selected TM image as the basis of remote sensing data. When selecting remote sensing data, we should select high-quality images with high definition, rich hue and less cloud and snow as far as possible. The quality of remote sensing data directly affects the interpretation accuracy of land use / land cover information and the extraction accuracy of environmental factors such as vegetation coverage and soil erosion. This study analyzes the impact of mineral resources development on the ecological environment. These environmental factors are the data basis of the study and play a key role in the research results. So it is very important to choose high quality remote sensing image.<br>
