目的
2
综合评价不同恢复治理措施在退化草场的应用效益,明确冀北坝上地区天然退化草场治理技术和应用条件,为坝上地区草场生态治理提供技术和应用经验,助力生态环境和乡村振兴协同发展。
方法
2
2022—2024年,选择沽源县白土窑乡新华村和九连城镇绿园村为试验样地,以围场、丰宁、张北、康保、尚义县5处自然草地为对照,设置切根+围封、施肥+围封、种草+围封、围封4种处理措施,分析不同措施的样地群落特征、地表特征、产草量及适口性等指标。
结果
2
①2 a年内,种草+围封可显著提高退化草地质量,且退化典型草原的效果优于退化草甸草原。应用种草+围封处理,退化典型草原和退化草甸草原年产草量干重分别增加54.25%和48.18%,适口性牧草干重年增长量分别为2.10%和1.20%; ②退化典型草原施肥+围封和退化草甸草原施肥+围封处理的植被覆盖度分别增加1.20%和1.60%,地表裸露占比分别减少0.60%和0.80%; ③切根+围封措施在一定程度上可提升植物群落多样性,但效果因地而异; ④围封措施效果最差,但优于对照样地。
结论
2
相比自然恢复,人为干预短期内可显著改善植物群落特征和生产力,但对植物群落多样性的影响总体不显著。对于冀北坝上轻度退化典型草原,有生产需求的推荐恢复措施顺序为:围封+种草、围封+施肥、围封+切根;无生产需求的草地宜采用围封。对于有旅游价值需求的退化草甸草原,宜采取施肥+围封,可改善群落特征,提升景观效果。
Objective
2
The application benefits of different restoration and management measures in degraded grasslands were comprehensively evaluated, and the technical and application conditions for the management of natural degraded grasslands in the Bashang area of northern Hebei Province were analyzed, in order to provide technical and application experience for the ecological management of grasslands in the Bashang area, and to support the coordinated development of the ecological environment and rural revitalization.
Methods
2
From 2022 to 2024, experimental plots were established in Xinhua village in Baituyao Township and Lvyuan Village in Jiuliancheng Town, Guyuan County, with five natural grasslands located in Weichang, Fengning, Zhangbei, Kangbao, and Shangyi counties as control plots. Several intervention measures were implemented, including enclosure + root cutting, enclosure + fertilization, enclosure + grass planting, and enclosure only. Indicators such as community characteristics, surface characteristics, grass yield, and palatability of each plot were systematically investigated and analyzed.
Results
2
① Within two years, the quality of degraded grasslands was significantly improved by enclosure + grass planting measures, with greater effectiveness observed in degraded typical grasslands compared to degraded meadow grasslands. The annual dry weight of grass yield increased by 54.25% and 48.18% in the degraded typical grasslands and degraded meadow grasslands under this treatment, respectively, while the annual dry weight of palatable forage grass increased by 2.10% and 1.20%, respectively. ② Enclosure + fertilization measures effectively increased vegetation coverage and reduced the proportion of bare ground, with vegetation coverage increasing by 1.20% and 1.60% annually, and bare ground decreasing by 0.60% and 0.80% annually in degraded typical grasslands and degraded meadow grasslands under this treatment. ③ Enclosure + root cutting measures could improve the plant community diversity to some extent, but the effectiveness varied by location. ④ Enclosure only was the least effective among the four measures, but still performed better than the control plots.
Conclusion
2
Compared with natural restoration, human intervention can significantly improve the plant community characteristics and productivity in the short term, but the overall impact on community species diversity is not significant. For the slightly degraded typical grasslands in the Bashang area of northern Hebei with production demands, the recommended order of restoration measures is enclosure + grass planting, enclosure + fertilization, and enclosure + root cutting. For grasslands without production demands, the measure of enclosure only is recommended. For degraded meadow grasslands with tourism value, the enclosure + fertilization measure is recommended to improve the community characteristics and enhance the landscape aesthetics.
