Abstract
- Over the past decades, croplands in China experienced rapid losses as a result of nationwide urbanization, industrialization, socioeconomic development, and implementation of ecological projects. These developments were driven by continuous economic reforms and environmental protection policies. Croplands are precious land resources influenced by overpopulation in China. Cropland losses threaten national food security. This study analyzed spatial patterns of cropland changes, driving forces, and its adaptation. Object-based approach was adopted to accurately measure cropland changes using remote sensing data. Conversion matrix and statistical regression model were used to explore impacts of socioeconomic factors on cropland changes. A case study on Beijing revealed that cropland in Beijing decreased by 47% in the past 35 years. Primary driving forces in cropland loss included urban expansion, implementation of ecological projects, orchard plantation, and water resource protection. Increased migration and economic development resulted in urban expansion. To promote sustainable development and to meet demands of urban and environmental protection, cropland adaptation was performed by increasing value-added commercial crop plantation, improving crop yield, and reducing cultivation intensity for effective water consumption.
