　　From a bird's-eye view, the forests in the Great Khingan Mountains are like a vast green canvas, gracefully unfurling across the expansive land in northeast China's Heilongjiang Province.

　　As one of China's largest state-owned forest bases, the Great Khingan Mountains are an important source and conservation area for rivers such as the Heilongjiang River and Nenjiang River, as well as those for major river tributaries, playing a role in enhancing grain production in the Songnen Plain.

　　Greater Khingan Forest Industry Group, a major forestry company in the area, manages a total area of 7.98 million hectares, including a forest area spanning 6.28 million hectares.

　　Over the years, the company has actively promoted the transition of ecological restoration from general protection to quality and efficiency enhancement, and from mere quantitative growth to increasing forest carbon reserves, proactively exploring a three-dimensional management model.
