    摘要:

    针对勉县至宁强县高速公路所采用的生态恢复类型, 选择土壤有机质、碱解氮、速效磷、植被覆盖度、播种植物的生长状况、当地植物的入侵种数及入侵种生长状况作为评价指标, 用聚类分析的方法对山区高速公路生态恢复情况进行分类评价, 通过聚类使27个代表性样本凝聚为8类, 与路域生态恢复进展情况相吻合, 取得了较好的评价效果。

    Abstract:

    Focusing on the ecological recovery type adopted in the highway from Mian County to Ningqiang County, the authors analyzed the classified situation of the ecological recovery in mountain area using the method of clustering analysis. Soil organic matter, alkali dissolving nitrogen, rapidly available phosphorus, vegetation coverage, and native plant invasion species and their growth state were selected as the evaluation indexes. Through the clustering analysis, 27 representative samples were reduced to 8, which may fit to the situation of the highway ecological recovery. Such an evaluation method has received a positive result.
