RESEARCH ON THE APPLICATION OF ECOLOGICAL RESTORATION TECHNOLOGY IN THE RESTORATION OF DEGRADED FOREST LAND

ABSTRACT

This paper discusses the application of ecological restoration technology in the restoration of degraded forest land, aiming at promoting the ecological restoration and sustainable development of degraded forest land through scientific restoration means. Firstly, this paper expounds the urgency and importance of restoration of degraded forest land, analyzes the severe challenges facing the current ecological environment, and clarifies the necessity of ecological restoration technology. Then, the application methods and effectiveness of key technologies such as vegetation restoration, soil improvement, soil and water conservation and biodiversity protection and restoration in the restoration of degraded forest land were introduced in detail. On this basis, the paper further analyzes the challenges faced by ecological restoration technology in practical application, such as the complexity of ecological environment, insufficient investment in capital and technology, insufficient public participation, long-term and sustainable. In order to cope with these challenges, this paper puts forward several optimization suggestions, including strengthening scientific research and technological innovation to deepen the theoretical cognition of ecological restoration and promote technological innovation; Increase capital investment and policy support, through the expansion of capital sources, the establishment of effective regulatory mechanisms and policy guidance.
