| 摘 要： | 以榆阳区小纪汗沙地矿区为例,选择樟子松、班克松、彰武松为主栽树种,通过多树种混交格状防风固沙林、块状混交防风固沙林、带状混交防风固沙林和常规造林不同造林模式的推广示范,达到改造沙地原有植被、增加防护植被类型、改变林分结构、探讨沙地矿区植被恢复造林模式的目的。提出多树种混交格状防风固沙林为最优模式,株行距5m×25m,建议推广应用。

| Abstract: | Taking Xiaojihan Sandy Land Mining Area in Yuyang District as an example, this paper chooses Pinus sylvestris Linn.var. mongolica Litv., Pinus banksiana and Pinus densiflora var. zhangwuensis as the main planting species. Through the mixed lattice windbreak and sand fixation forest with multiple tree species, such as blocky mixed windbreak and sand fixation forest with multiple tree species, multi-tree species mixed belt windbreak and sand-fixing forest, conventional afforestation and so on, the original vegetation is reformed, the type of protection vegetation is increased, and the stand structure is changed. As an innovative point, the optimummodel of mixed lattice windbreak and sand fixation forest with multiple tree species was put forward, plant-row spacing 5 m× 25 m, which was recommended to be popularized and applied. |
