摘要
随着全球气候变暖,局部极端高温天气对植被的影响越来越受到关注。本文论述了高温胁迫对植物生长、光合作用、生理生化和分子机制的损伤与限制,以及为缓解高温胁迫下的限制作用,接种丛枝菌根真菌(AMF)对促进植物生长、抗氧化物的活性和含量、抗病虫害的能力、光合效率以及耐热基因等系统的影响。考虑西部煤矿开采破坏区域地质结构,严重影响植被生理生态的健康发展,降低植物覆盖度,更容易引起极端高温气候的发生,严重限制矿区生态环境修复,进一步探讨了接种AMF对矿区植被、土壤生态修复的作用,展示了未来深入研究AMF的方向,为西部矿山恢复生态的可持续发展提供了理论依据。
With global warming,more attention has been paid to the effect of extreme high temperature weather on plants.In this paper,the damage and limitation of high temperature stress on plant growth,photosynthesis,physiological and biochemical,and molecular mechanisms were discussed.In order to promote the resistance of plants to high temperature stress,inoculating arbuscular mycorrhizal fungi(AMF)to promote plant growth,the activity and content of antioxidants,the ability to resist plant diseases,photosynthetic efficiency,heat-resistant genes systems.The coal mining in the west destroys the regional geological structure,seriously affects the healthy development of vegetation physiology and ecology,reduces the plant coverage rate,and is more likely to cause the occurrence of local extreme high temperature climate,which severely restricts the ecological environment restoration of the mining area.We discussed the effect of AMF inoculation on the ecological restoration of vegetation and soil in the mining area,and showed the direction for in-depth study of AMF in the future,which provided a theoretical basis of the sustainable development of mine ecological restoration of western China.
