Sažetak

The ecologically fragile areas of Southwest China feature a complex topography of interwoven mountains, hills, and basins. Infrastructure construction and mining activities in these regions often create high-steep rock slopes that are prone to geological hazards such as rockfalls and landslides. Due to extensive rock exposure and low vegetation cover resulting from mining, natural recovery is extremely slow, posing a major challenge for ecological restoration. Based on local site conditions and the need for coordination between restoration efforts and the surrounding environment, this study proposes a novel method using an integrated ecological protection and restoration system combined with a water supply system. This approach effectively ensures the stability of the plant growth substrate on steep slopes, supports vegetation survival, and enables long-term sustainable growth. Based on the research findings, the following countermeasures are recommended: focusing on the construction of an ecological security guarantee system in regional ecologically fragile areas; proactively adapting to new trends in economic development; enhancing management and technical capabilities for ecological protection; alleviating the pressure of population growth on resources and the environment; strengthening international cooperation in the field of ecological security; and prioritizing the protection and construction of ecological barriers on plateaus. The results indicate that the comprehensive ecological security index in Southwest China's ecologically fragile areas has been steadily improving year by year. Although the current security level remains in the range between "poor" and "warning," the overall ecological environment is moving toward a positive development trajectory.
