从“两难”到“共赢” 福建泉州探索“林电共安”新路径

Core Viewpoint - Fujian Province, with the highest forest coverage rate in China, faces significant challenges related to the "tree-line conflict," which poses risks of wildfires and electrical safety. The State Grid Quanzhou Power Supply Company collaborates with forestry departments to explore new pathways for "forest-electricity safety," aiming for a balance between electrical grid safety, forest sustainability, and increased income for residents [1]. Group 1: Mechanism Innovation - The collaboration between the State Grid Quanzhou Power Supply Company and relevant departments aims to streamline the approval process for power grid projects in forest areas, reducing the approval time from approximately 2 months to under 7 working days through the establishment of an "ecological forest index reserve" [2]. - The innovative model allows for centralized pre-review and dynamic allocation of forest land usage, significantly improving project efficiency, as demonstrated by the rapid approval of the 110 kV Yangmei Substation, which was completed 4 months ahead of schedule [2]. Group 2: Safety and Economic Balance - The "tree species replacement" initiative addresses safety concerns by encouraging farmers to replace tall, hazardous trees with low-growing, economically beneficial crops, thus balancing safety and economic benefits [3]. - A strategic agreement signed in March 2024 aims to implement a vegetation replacement plan over 9,400 acres, promoting the cultivation of crops like oil tea and iron skin orchid in place of tall trees [3]. - Successful examples include the transformation of land around the 220 kV Shichao Substation, where banana trees were planted, yielding over 5,000 pounds per acre, and the conversion of a power corridor into carrot fields, generating annual revenues exceeding 4,000 yuan per acre [3]. Group 3: Technological Empowerment - The use of digital tools, such as drone inspections and 3D modeling, has enhanced the ability to identify electrical line hazards, with over 3,500 3D scanning images created and 435 high-risk tree obstacles identified [5]. - The introduction of an "edge computing module" during summer inspections has improved the efficiency of hazard identification and response, reducing operational time by over 50% and enabling immediate action on identified tree hazards [6].
