- 摘要:
- 通过在共和县沙珠玉乡实施的荒漠化综合治理试验，探讨了在高寒干旱荒漠地区采用深栽造林和不同沙障类型的不同沙障形式的荒漠治理技术，同时采用了保水剂措施进行试验。结果表明：深栽造林树苗的成活率高达91.7%，比常规植苗造林的成活率提高29.2%，而沙障类型中格状式沙障形式比行列式沙障形式苗木的成活率提高30%～56%，并且粘土格状式1.5 m×2 m的沙障第2年不同生境的造林地植被盖度达到65%～70%，得出格状式黏土沙障和深栽造林是荒漠区植被恢复的首要措施.
- Abstract:
- Through implementing comprehensive control of desertification experiment in Shazhuyu township of Gonghe County, the afforestation and the different sand barrier are used in the high and cold arid wilderness area, simultaneously used the water retention agent measure to carry on the experiment.The result indicated that, the deep afforestation seedling, the survival rate reaches as high as 91.7%, compared to the convention, the survival rate increased by 29.2%.But in the sand barrier type the standard shape type sand barrier form enhances survival rate 30%～56% compared to the determinant sand barrier form, and the clay standard shape type 1.5 m×2 m sand barrier in second year in different habitat area vegetation degree of cover achieves 65%～70%.The shape type clay sand barrier and deep afforestation is the most important measure which restores wilderness area vegetation.
