基于植被重建的宁东矿区煤矸石山立地类型及其特征

以宁东矿区煤矸石山为研究对象，选取微地形、海拔、覆土厚度、土壤质地等10个立地因子进行调查分析，利用主成分分析和聚类分析等方法，划分煤矸石山立地类型。应用主成分分析法确定出主导立地因子为：微地形、覆土厚度、土壤质地；再依据主导因子对研究样地进行聚类分析划分出宁东矿区煤矸石山３个立地类型组，５个立地类型亚组，８个立地类型。

Taking the coal gangue piles in the Ningdong Mining Area as the research object, 10 site factors including micro-topography, altitude, thickness of soil cover, and soil texture were selected for investigation and analysis. Principal Component Analysis (PCA) and Cluster Analysis were utilized to classify the site types of the coal gangue piles. The dominant site factors were determined as micro-topography, thickness of soil cover, and soil texture through PCA. Subsequently, cluster analysis was conducted on the study plots based on these dominant factors, dividing the coal gangue piles in the Ningdong Mining Area into 3 site type groups, 5 site type subgroups, and 8 site types.
