- 摘要:
- 量化分析和识别自然植物群落所处的状态，对于植被自然恢复人工调控具有重要的指导意义。利用灰色关联分析法（Grey Relational Analysis，简称GRA法），通过建立参照系，对安塞5个不同恢复时间的自然群落所处的状态进行分析，结果表明，该方法可以比较准确地识别不同自然恢复群落在演替中的位置和状态，5个自然群落的排序为：沙棘>铁杆蒿>白羊草>赖草>猪毛蒿。就不同指标对识别指标的贡献率看，衡量植被演替程度的指标，如演替指数、演替度贡献率较大。而有机质、含水量、重要值、丰富度指数及恢复度与植被恢复状态的识别指标的关联系数都在0.5以上。这表明，除传统的演替指标外，要准确识别植物群落所处的状态，物种之外的其他因素亦具有非常重要的地位。但灰色关联分析法作为一种基于参照系与系列数据间相似度的有效而准确的识别模型，在植被研究中的应用较少，仍需开展较深入的工作。
- Abstract:
- Understanding and identification of the natural communities in vegetation succession is of great importance to the acceleration of vegetation succession by human intervention.This paper aims at exploring a new method,Grey Relational Analysis (GRA),to analyze and identify the state of 5 natural communities in vegetation succession in Ansai County,a loess hilly region.In order to do this,a reference system has been established and used as a yardstick to measure these 5 communities’ state.The results showed that GRA is effective and accurate in identifying the state of natural communities in vegetation succession.The 5 natural vegetation communities showed an order as follows according to their values: Hippophae rhamnoides communities>tripolium vulgare communities>bothriochloa ischaemum communities>Leymus scalinus communities>Artemisia scoparia communities.However,the components of indicators have different contributions to the evaluation.The succession indexes contribute more than other indexes.Yet the soil organic matter,soil water content,importance value,richness and restoration degree also have higher conjunction index value (>0.5).This indicates that environmental factors such as soil are as important as succession indexes in determining the state of natural communities in vegetation succession,especially for the human intervention of vegetation succession.However,the Grey Relational Analysis,as a model based on the similarity between the reference system and time series data,was applied in few vegetation science studies,thus needing more further research in the future.
