Tóm tắt

Nghiên cứu này tập trung phát triển một hệ thống tự động giám sát diễn biến lớp phủ rừng tại Việt Nam thông qua nền tảng Google Earth Engine (GEE) và các chỉ số thực vật thông dụng. Trước bối cảnh mất rừng và biến đổi khí hậu đang gia tăng, hệ thống này cung cấp giải pháp nhanh chóng, chính xác, và hiệu quả về chi phí trong việc theo dõi biến động rừng mà không đòi hỏi đầu tư lớn vào cơ sở hạ tầng. Các chỉ số NDVI, EVI, SAVI, NDWI, NBRI, GCI, và BSI được áp dụng để đánh giá sức khỏe và mức độ che phủ của rừng. Nghiên cứu nhấn mạnh vai trò quan trọng của công nghệ viễn thám trong giám sát biến động lớp phủ rừng, tận dụng dữ liệu vệ tinh để phân tích các biến động về diện tích và tình trạng sức khỏe hệ sinh thái. Nền tảng GEE, với khả năng xử lý quy mô lớn, cho phép phân tích diện rộng và phát hiện sớm các hiện tượng như phá rừng, cháy rừng, hoặc suy thoái rừng. Hệ thống này đóng vai trò hỗ trợ quan trọng trong việc ra quyết định quản lý và bảo tồn rừng bền vững, đồng thời tự động hóa quy trình theo dõi, góp phần nâng cao hiệu quả quản lý tài nguyên và bảo vệ đa dạng sinh học.
