目的
2
研究草皮掘取后的多层堆置技术以及迹地草皮回植关键技术,为高寒草甸资源保护和工程创面修复提供科学依据和技术支撑。
方法
2
以西藏自治区芒康县拉乌山山顶高寒草甸为研究对象,通过实施草皮人工剥离、开展不同草皮叠置层数(2~5层)的叠置试验以及草皮回植试验,并对不同叠置层数下草皮叠置保存率、草皮回植存活率和不同时期植物物种种类进行比较分析,分析草皮剥离、堆存、回植的技术要点。
结果
2
草皮叠置整体保存率为96.89%,在叠置层数超过2层时保存率显著升高。草皮回植试验的整体存活率为87.96%,不同叠置层数之间的存活率差异并不显著。草皮堆叠导致物种种类减少,群落结构趋于简化;草皮回植后,物种种类逐渐恢复到与原生植被相近水平。综合空间利用和存活率因素,本研究推荐草皮叠置5层堆存。
结论
2
高寒地区草皮剥离后回植是有效的植被恢复措施,推荐采用叠置5层的堆存方式。
Objective
2
The multi-layer turf stacking techniques after turf stripping and key techniques for turf replanting on disturbed sites were investigated, in order to provide a scientific basis and technical support for alpine meadow conservation and engineering surface restoration.
Methods
2
Taking the summit alpine meadow of La’u Mountain at Mangkang County, Xizang Autonomous Region as the study site, artificial turf stripping, stacking with 2—5 layers, and turf replanting experiments were conducted. Turf preservation rates during stacking, survival rates after replanting, and plant species composition across different stacking layers and periods were compared, and key technical points of turf stripping, stacking, and replanting were analyzed.
Results
2
The overall preservation rate of stacked turf was 96.89%, and it increased significantly when more than two layers were stacked. The overall survival rate after turf replanting was 87.96%, with no significant difference among different stacking layers. Turf stacking reduced species diversity and simplified community structure. After replanting, species diversity gradually recovered to a level similar to that of the native vegetation. Considering spatial efficiency and survival rate, this study recommended stacking turf in five layers.
Conclusion
2
In alpine meadows, replanting after turf stripping is an effective measure for vegetation restoration. It is recommended to use a stacking method of five layers.
