摘要: [目的]探讨不同修复措施对退化草地的恢复效果。[方法]以内蒙古通辽市扎鲁特旗境内的中、重度退化草地为研究对象,采用围封(TW)、围封+补播(TB)、围封+补播+施肥(TBS)3项措施进行修复。以外围放牧样地作为对照(CK),于2016—2019年连续监测并比较不同修复措施下退化草地的植被高度、盖度、地上生物量。[结果]2016—2019年,TW、TB、TBS处理的植被高度、盖度、地上生物量均显著(P<0.05)高于放牧(CK)处理;修复当年(2016年),TB和TBS处理的植被高度、盖度、地上生物量均显著(P<0.05)高于TW处理,并且TBS处理的植被高度、盖度显著(P<0.05)高于TB处理;2017年,TBS处理的植被高度和地上生物量显著(P<0.05)高于TW和TB处理,TB和TBS处理的植被盖度显著(P<0.05)高于TW处理;2018年,TB和TBS处理的植被地上生物量显著(P<0.05)高于TW处理,TBS处理的植被地上生物量显著(P<0.05)高于TB处理;2019年,TB和TBS处理的植被盖度和地上生物量显著(P<0.05)高于TW处理。[结论]围封、围封+补播、围封+补播+施肥3项措施对中、重度退化草地都表现出较好的修复效果,以围封+补播+施肥的修复效果最佳。

Abstract: [Objective] This study was conducted to assess the effects of different remediation measures on the restoration of degraded grassland. [Method] A restoration trial with three measures, including enclosure (TW), enclosure+supplementary sowing (TB), and enclosure+supplementary sowing+fertilization (TBS), was performed on the moderately and severely degraded grasslands in Jarud Banner, Tongliao City, Inner Mongolia. Using the peripheral grazing plots as control (CK), the vegetation height, coverage and above-ground biomass of the degraded grasslands were continuously monitored and compared under different remediation measures from 2016 to 2019. [Result] During the whole monitoring period, the vegetation height, coverage and above-ground biomass of TW, TB and TBS treatments were all significantly (P<0.05) higher than those of CK. In the current year of restoration (2016), the vegetation height, coverage and above-ground biomass of TB and TBS treatments were significantly (P<0.05) higher than those of TW treatment, and the vegetation height and coverage of TBS treatment were significantly (P<0.05) higher than those of TB treatment. In 2017, the vegetation height and above-ground biomass of TBS treatment were significantly (P<0.05) higher than those of TW and TB treatments, and the vegetation coverage of TB and TBS treatments was significantly (P<0.05) higher than that of TW treatment. In 2018, the vegetation above-ground biomass of TB and TBS treatments was significantly (P<0.05) higher than that of TW treatment, and the vegetation above-ground biomass of TBS treatment was significantly (P<0.05) higher than that of TB treatment. In 2019, the vegetation coverage and above-ground biomass of TB and TBS treatments were significantly (P<0.05) higher than those of TW treatment. [Conclusion] The remediation measures of enclosure, enclosure+supplementary sowing, and enclosure+supplementary sowing+fertilization all had good restoration effects on moderately and severely degraded grasslands, with enclosure+supplementary sowing+fertilization having the best restoration effect.
