北京市延庆县玉渡山公路是北京玉渡山自然风景区的南大门,是通往玉渡山风景区腹地的唯一的盘山通道,蜿蜒曲折,绵延7.5km,座落于北京市张山营镇境内,是海坨山系的前山脸,是北京通往我国西北部地区的重要交通走廊,其地理位置显要。此处生态环境直接关系到延庆县国家级生态示范县的建设和旅游事业的发展,为此,将玉渡山公路两侧裸岩及流沙区确定为爆破造林工程地段,以此恢复生态景观,提升景观档次,从根本上治理本地区的生态环境。基于此,从10个方面阐述了在工程中采取的行之有效的技术措施:1)裸岩区人工凿石坑;2)流沙区用U型铁板挖坑;3)坑穴铺膜袋;4)采用pvc管道送土回填;5)滑轮索道运苗;6)TC保水剂抗旱保墒;7)铺设生态垫;8)用特制铁镢栽植容器苗;9)播草(种树)固沙;10)后山引水浇灌。
Yanqing County, Beijing Yudu Hill Road is Beijing’s Jade Mountain Scenic Area south gate, is leading to the hinterland of Jade Mountain Scenic Area Panshan channel, winding, stretching 7.5km, is located in Beijing Zhang Shan In the territory of the town, it is the former mountain face of the Tuo Tuo Mountain and the important transportation corridor leading to the northwestern part of our country from Beijing. Its geographical position is significant. Here the ecological environment is directly related to the development of national ecological demonstration counties in Yanqing County and the development of tourism. To this end, the boulders and quicksand areas on both sides of the Jade Mountain Road are identified as the blasting and afforestation sites in order to restore the ecological landscape, Enhance the landscape grade, fundamentally control the ecological environment in the region. Based on this, the effective technical measures adopted in the project are elaborated in 10 aspects: 1) artificial rock excavation in bare rock area; 2) U-shaped iron digging in quicksand area; 3) ; 4) using pvc pipe backfill soil; 5) pulley rope transport; 6) TC water retention agent moisture preservation; 7) laying ecological mat; 8) planting iron container seedlings; ; 10) after the mountain water diversion.
