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.
