抚顺西排土场矸石山阴坡随着排矸年限的增加,物种多样性发生变化,物种数由初期的4科5种增至后期14科29种。植被由最初的鹅绒藤+豚草+刺蒺藜群落,逐步演变到榆树群落。在阴坡,不同排矸年限的样地,植物群落多样性指数随着排矸时间的延长而增加;物种综合多样性指数、丰富度指数与排矸年限呈显著正相关关系。
撫順西排土場矸石山陰坡隨著排矸年限的增加,物種多樣性髮生變化,物種數由初期的4科5種增至後期14科29種。植被由最初的鵝絨籐+豚草+刺蒺藜群落,逐步縯變到榆樹群落。在陰坡,不同排矸年限的樣地,植物群落多樣性指數隨著排矸時間的延長而增加;物種綜閤多樣性指數、豐富度指數與排矸年限呈顯著正相關關繫。

On the shady slope in Fushun Western Waste Dump, with the scheduled length of the waste rocks, the number of species from the initial four families and five species increased to 14 families and 29 species. Vegetation from the very beginning of Cynanchum chinense, Ambrosia artemisiifolia L. , Puncturevine caltrop fruit community turned to the Ulmus pumila L. community. The species diversity index, richness index and dumping years have significantly positive correlation.
