| 摘 要： | 通过在鄂尔多斯市准格尔旗暖水乡露天矿区对不同立地条件下不同树龄沙棘生物量以及树高、冠幅、地径的调查,研究沙棘在煤矿特定立地条件下的生长状况。结果表明：苗圃地沙棘长势最好,矿区道路旁和矿区排土场外侧边坡次之。通过分析相同立地条件下不同树龄沙棘地上生物量与地下生物量的相关性,表明5年生沙棘的相关性最好（R2=0.9399,P=0.0064）,2年生次之,4年生最差（R2=0.6928,P=0.083）。沙棘树高、冠幅、基径三者之间的相关性显著,相关系数均大于0.9。

| Abstract: | Based on investigating the biomass,tree height,diameter and crown of different-age Hippophae rhamnoides in Nuanshui Opencast Coalmine,Zhungeer Qi,Erdos in different site conditions,the growth of Hippophae rhamnoides had been studied in specified site condition in coalmine.The results showed： the best conditions for the growth of Hippophae rhamnoides was nursery land,and mining area near the road and the dump area were worse than nursery land.Comparing the correlation of Hippophae rhamnoides about underground biomass and ground biomass for different-aged Hippophae rhamnoides under the same site condition,we found that the correlation in 5-year was the best（R 2=0.9399,P=0.0064）,2-year Hippophae rhamnoides was worse,4-year was the worst（R 2=0.6928,P=0.083）.The correlation of tree height,crown,base diameter of Hippophae rhamnoides was significantly,and the correlation coefficient is higher than 0.9. |
