摘要
针对西北干旱荒漠区排矸场生态型植被模式生态恢复效果不明确的问题,在宁东煤炭基地排矸场选取25个样地进行调查,利用二段式命名法划分立地类型,利用双向指标种分析法划分不同生态型植被模式,并从生态适应性、生态功能性、经济性3个层面选取指标对生态恢复效果进行评价,构建层次分析—熵权组合赋权模糊物元模型对各样地生态恢复综合效果进行评价。立地类型划分为8类;生态型植被模式包括4类乔木模式和4类灌木模式;不同模式的生态适应性和生态功能性存在明显差异,生态型植被模式的筛选应更加侧重于植被的生态适应性;根据综合效果评价结果,分别筛选出不同立地类型最适宜的生态型植被模式。
Responding to the problem of unclear ecological restoration effect of different ecotype vegetation patterns in the coal gangue dumpings of mining areas in the arid desert area of Northwest China;25 sampling sites were selected in Ningdong Coal Base to investigate, site types were divided by two-stage nomenclature, two-way indicator species analysis was used to classify different ecotype vegetation patterns, the restoration effects of different ecotype vegetation patterns were evaluated from the three levels of ecological adaptability, ecological functionality, and economy, and a hierarchical analysis-entropy combination weight fuzzy matter element model was constructed to comprehensively evaluate the restoration effects of each sample site;site types were classified into eight categories, ecotype vegetation patterns included 4 types of tree patterns and 4 types of shrub patterns, there were significant differences in the ecological adaptability and ecological functionality of different patterns, the economic ratio is negligible, and based on the results of the comprehensive effect evaluation, the suiTab. ecological vegetation patterns for each of the eight land types were screened out.
