The slope soil and water conservation-oriented ecological agriculture is an innovative technological framework specifically designed for the management of slope farmlands in mountainous regions that are highly susceptible to soil erosion. This approach represents the practical application of ecological agriculture in the southwest alpine canyon area, providing valuable guidance for the establishment of ecological civilization and the pursuit of sustainable agricultural development. The method plays a crucial role in addressing soil erosion challenges in these sloped landscapes. The Southwest Alpine-Canyon Area of China is situated at the convergence of the Qinghai-Tibet Plateau ecological barrier, the Sichuan-Yunnan ecological barrier, and the Yangtze River ecological zone. Although the area's ecological environment is fragile, it possesses rich natural resources and functions as an important cultural center for a variety of ethnic minority groups. extensive areas of sloped farmland, and severe soil erosion challenges. Inefficient agricultural practices significantly impede agricultural modernization in the region, and the ecological agriculture development in this area lags behind the national average. The adoption of slope water and soil conservation-oriented ecological agriculture not only facilitates soil erosion control, enhances land productivity, and preserves the mountainous environment but also stimulates regional economic growth and increases farmers' incomes. This paper synthesizes current practices by identifying five prevalent models of ecological agriculture in southwest alpine canyon areas: ecological planting, ecological breeding, agroforestry, agro-tourism, and innovative integrated development. These models arise from variations in terrain, climate, and water resources. Systematically analyze and summarize the concepts, specific practices, and primary distribution areas of five ecological agricultural models. Furthermore, it examines the challenges faced in advancing ecological agriculture within this region. Additionally, the paper delves into the concept and characteristics of slope water and soil conservation-oriented ecological agriculture while providing a comprehensive analysis of two key technical strategies: "contour reverse slope terrace" method for land preparation and "interception + collection + photovoltaic irrigation" integrated technique. It discusses their principles, deployment strategies, as well as resulting benefits. The findings suggest that slope soil and water conservation-oriented ecological agriculture not only promotes sustainable agricultural practices but also ensures environmental protection in mountainous areas where droughts are prevalent along with water scarcity issues and soil erosion concerns. This approach demonstrates significant potential for widespread application while offering practical insights for managing soil erosion on sloped farmlands. Finally, the paper concludes by recommending further research into additional technical models related to slope soil and water conservation-oriented ecological agriculture in order to refine these strategies and provide essential scientific support for managing soil erosion on mountainous slope farmlands.
