Analysis of Ecosystem Protection and Sustainable Development Strategies—Evidence Based on the RWEQ Model on the Loess Plateau, China

Abstract

Environmental sustainability and high-quality development are global issues since soil deterioration and potential desertification are caused by human activities and global climate change, especially in arid and semi-arid areas. The Loess Plateau is one of the most severely eroded regions in the world. Since the “Grain for Green Program” was established on the Loess Plateau in the late 1990s as a result of the degradation of the soil, it has been an important state policy and demonstration project for ecological protection and sustainable development in China. Therefore, understanding the spatiotemporal changes of soil wind erosion, such as yearly and monthly fluctuations in various periods, under the scenarios of global climate change and human activities, is crucial for carrying out soil conservation initiatives in the Yellow River basin. The revised wind erosion equation (RWEQ) model was applied in this study to evaluate the dynamics of soil wind erosion on the Loess Plateau, China. The soil wind erosion was evaluated on the Loess Plateau from 1981 to 2019 to provide a creative idea for managing ecosystems at the regional scale. By examining the case of the Loess Plateau, we hope to be better able to comprehend the significance of putting environmental protection projects into action to enhance the ecological environment and the well-being of locals, as well as to offer recommendations for the future creation of effective and sustainable development strategies.
