超54万亩，“燕山山地南部生态综合治理工程”完成林业建设任务

Core Viewpoint - The "Beijing Yanshan Mountain South Ecological Comprehensive Governance Project" has successfully completed over 540,000 acres of forestry construction, marking a strong start for the sixth phase of the national "Three-North" project [1][2]. Group 1: Project Overview - The project involves five mountainous areas and two state-owned forest farms, enhancing the stability and diversity of the Yanshan Mountain forest ecosystem, which is crucial for Beijing's ecological security [2]. - The project is part of a broader plan that includes various ecological governance initiatives to be completed by 2030, such as afforestation and restoration of degraded forests [3]. Group 2: Ecological Strategies - The project emphasizes quality over quantity in forestry management, focusing on improving forest quality, ecosystem services, and carbon sequestration capabilities [4]. - Specific techniques include using drought-resistant and cold-resistant native tree species, and implementing restoration methods to enhance forest stability and diversity [4][5]. Group 3: Technological Integration - The use of drones for transporting seedlings has improved the survival rate of saplings during the critical spring planting season, addressing challenges posed by the complex terrain [6][8]. - A smart management platform has been established to monitor fire prevention, pest control, and biodiversity, integrating real-time data analysis for effective forest management [9].
