研究目的
To detect the land use change using remote sensing for sustainable land use planning in Upper Rib watershed.
研究成果
The study revealed significant land use changes in Upper Rib watershed over an 11-year period, with agricultural land increasing by 13.78% and grassland decreasing by 15.97%. These changes were attributed to population growth and increased interest in croplands. The findings underscore the importance of sustainable land use planning to mitigate negative impacts on the environment.
研究不足
The study is limited by the spatial resolution of the satellite images (30 m × 30 m) and the accuracy of ground truth points. Potential areas for optimization include the use of higher resolution images and more comprehensive ground truth data.
1：Experimental Design and Method Selection:
The study utilized satellite images from 2007 and 2018 for land cover change detection. Maximum likelihood classification in ERDAS Imagine was used for image classification.
2：Sample Selection and Data Sources:
Satellite images were downloaded from USGS Earth explorer, with ground truth points collected for verification.
3：List of Experimental Equipment and Materials:
Landsat ETM+ images with a spatial resolution of 30 m × 30 m were used.
4：Experimental Procedures and Operational Workflow:
Images were pre-processed, classified using supervised classification, and accuracy was assessed using ground truth points.
5：Data Analysis Methods:
Accuracy assessment was performed using error matrices, and land use changes were quantified.
