过牧及封育对红砂荒漠植被演替的影响 |
| 2. | Spatial distribution characteristics of stable carbon isotope compositions in desert plant reaumuria soongorica
荒漠植物红砂稳定碳同位素组成的空间分布特征 |
| 3. | Seed germination responses of reaumuria soongorica and zygophyllum xanthoxylum to drought stress and sowing depth
红砂和霸王种子萌发对干旱与播深条件的响应 |
| 4. | Moreover , the effect of heavy metal pollution on soil microbial indexes was significant in red sandy soils
两种土壤比较，以上微生物活性指标对重金属胁迫的响应程度在红砂泥上表现更为明显。 |
| 5. | Reaumuria soongorica and haloxylon ammodendron were dominant species occupying big niche breadth , and other species are companion
2769 ) 。生态位宽度较大的红砂和梭梭为优势种，其余草本植物为伴生种。 |
| 6. | 4 reaumuria soongorica and haloxylon ammodendron in desert - oasis ecotone show random distribution . the seedling of h . ammodendron shows clump distribution
4 、过渡带红砂和梭梭服从随机分布，梭梭幼苗表现为聚集分布。 |
| 7. | Two incubation experiments were conducted to evaluate the effect of cadmium and lead applied singly on soil microbial activities and functional diversity of microbial community in red clayey soil and red sandy soil
以红黄泥和红砂泥两个土属作为供试红壤，采用室内培养方法对外加镉、铅污染红壤的微生物活性及群落结构进行了研究。 |
| 8. | The results showed that the higher genetic diversity and the genetic differentiation existed in the population of reaumuria soongorica , which was composed of 7 subpopulations and 136 individuals , generated by 15 primers . 71 loci had been detected and 69 were polymorphic
15条随机引物对红砂7个亚种群的136个个体进行扩增，共检测71个位点，其中多态位点69个。 |
| 9. | Additionally , through the use of clustering analysis , principal factor analysis and the correlation analysis , we found that the genetic structure of natural population reawnuria soongorica was related to the ecological factors ( soil factors mainly ) of the oasis - desert transitional zone
而其它土壤生态因子则与红砂的遗传多样性指数的相关性均不显著( p 0 . 05 ) 。表明红砂个体的分布可能与过渡带土壤的某些易溶性盐分相关。 |
| 10. | The results showed that the capability of reaumuria soongorica in seed actual reproduction and artificial restoration was positively correlated with disturbance levels ; the capability of restoration varied with the characteristics of disturbance factors , of which water was the key factor
结果表明，红砂种子更新恢复能力与干扰水准呈正相关；干扰因数的特徵不同，则更新恢复能力不同；尤其水分因数参与对红砂种群的自然更新与人工辅助恢复起著关键性的作用。 |
