摘要
以南京幕府山矿区废弃地自然恢复的植被优势种群为对象,对构树及其伴生树种的生态位宽度和生态位重叠进行了研究。结果表明:研究的9个树种的生态位总体比较接近,都有比较宽的生态位,从群落形成的时间分析,这些树种是在矿区废弃地上的先锋树种,对废弃地有较强的适应能力。因此,在人工恢复这一地区矿区废弃地植被时,可以选用这些树种。构树的生态位较宽,而其与其他树种的生态位重叠却不是很大,构树在一定时期内,还是矿区废弃地上植物群落的最主要的优势树种,是矿区废弃地最适应的树种之一,可以作为本地区矿区废弃地植被恢复的首选树种。
Basing on the investigation on 5 plots of Broussonetia papyrifera population and main associated species naturally revegetabled in mine spoil Nanjing Mufu Mountains, the niche breath and niche overlap of the main species were studied. The results showed that the niche breath of 9 species are wide, and that the species are pioneer in mine spoil Nanjing Mufu Mountains, the niche breath of Broussonetia papyrifera is wide, but the niche overlap with other species is little. Broussonetia papyrifera is the best species for the revegetaion in mine spoil in Mufu mountain of Nanjing.
