摘要
武陵山喀斯特区域是石漠化重点治理区之一,探讨全球变暖情景下武陵山喀斯特石漠化地区植物群落演替是维持生态可持续发展的关键问题。本文以武陵山喀斯特地区为背景首次提出了物种生态位宽度的概念,并分别从武陵山喀斯特地区植被时空变化、气候与环境、植物群落抗旱生理因素三个方面分析了武陵山喀斯特地区植物群落干旱性特征。在此基础之上,本文构建了基于Beverton-Hot和Lotka-Volterra模型的生态位宽度演替模型和NDVI演替模型,并展示了演替模型的应用性。本研究对全球变暖情景下武陵山喀斯特地区的生态保护具有一定的参考意义。
The karst area of Wuling Mountain is one of the key control areas of rocky desertification. It is a key issue to maintain sustainable ecological development to explore the succession of plant communities in the karst area of Wuling Mountain under the global warming scenario. In this paper, the concept of species niche width was proposed for the first time in the karst area of Wuling Mountain. At the same time, the aridity characteristics of plant communities in the karst area of Wuling Mountain were analyzed from three aspects: spatiotemporal variation of vegetation, climate and environment, and physiological factors of plant community drought resistance. On this basis, this paper constructs a niche width succession model and a succession model based on the Beverton-Hot and Lotka-Volterra, and demonstrates the applicability of the succession model. This study is useful for the ecological conservation of the Wuling Mountain Karst region under the global warming scenario.
