东北黑土区侵蚀沟生态治理与耕地资源可持续利用研究OA

The northeast black soil region is the core guarantee of national food security in China.The evolution of erosion gullies has caused cultivated land degradation and ecological risks.In accordance with the national black soil protection policy and taking the practice of Horqin Right Front Banner,Hinggan League as a reference,this paper explores an engineering-biological-information technology collaborative system for erosion gully management.By adopting ecological engineering measures such as check dams and gully head protection,as well as cultivated land quality improvement measures,the expansion of erosion gullies is restrained,soil and water loss is mitigated,and farmland productivity is improved.This study provides a replicable model for farmland protection and ecological sustainable development in black soil regions,and supports national food security and ecological civilization construction.
