| 摘 要： | 通过对北京首云铁矿沙厂矿区3个不同自然恢复年限植物群落的实地调查,计算分析自然恢复植物种群生态位宽度、生态位重叠程度,总结自然恢复植物种群的生态位变异规律。结果表明：自然恢复5-15 a的植物群落中,籽蒿、榆树的生态位宽度较大;自然恢复16-25 a的植物群落中,榆树、猪毛蒿、臭椿、荆条生态位宽度较大;自然恢复26-35 a的植物群落中,荆条生态位宽度较大。随自然恢复年限的增加,沙厂矿区自然恢复植物种群之间的生态位重叠程度逐渐升高。

| Abstract: | Based on the investigation of vegetation under 3 natural restoration periods on Shachang mining area in Beijing Shouyun Iron Ore,the niche breadth and the niche overlap were researched for analyzing the niche discipline of plant populations under natural restoration.The results show that the species of big niche breadth during 5 to 15 years restoration include Artemisia sphaerocephala,Ulmus pumila.The species of big niche breadth during 16 to 25 years restoration include Ulmus pumila,Artemisia scoparia,Ailanthus altissima,Vitex negundo.The specie of big niche breadth during 26 to 35 years restoration includes Vitex negundo.The niche overlap between the plant populations increases with time going on. |
