摘要
选取稀土矿治理地为研究对象,探讨了不同治理年限的稀土矿治理地植被恢复状况及其植物多样性变化。结果表明,从时间上看,随着治理年限的增加,草本层Patrick丰富度指数呈上升的趋势,Alatalo均匀度指数则反之,灌木层Alatalo均匀度指数、Shannon-Wiener多样性指数呈上升的趋势;从空间上看,Alatalo均匀度指数、Shannon-Wiener多样性指数和Simpson优势度指数,灌木层均大于草本层;芒萁的盖度与高度随着治理年限的增加,呈现上升的趋势。
The rare earth elements mining area of Fujian Province were selected, and the change of plant recovery and diversity in ditlerent management period was analyzed. The results showed that： in terms of time, Patrick richness index of field layer was higher with increasing of management time, but Matalo homogeneity index was opposite. Matalo homogeneity index and Shannon-Wiener diversity of shrub layer would drop with the time being. In the aspect of the space, the Matalo homogeneity index, Shannon-Wiener diversity and Simpson dominance index of shrub layer was bigger than field layer. The covering degree and height of Dicranopteris dichotoma were on the rise with management time growing.
