| 8. | Soil nitrogen regime and the relationship between aboveground green phytobiomass and soil nitrogen fractions at different stocking rates in the xilin river basin , inner mongolia 退化草地恢复过程中土壤氮素状况以及与植被地上绿色生物量形成关系的研究 |
| 9. | A case study in the xilin river basin of inner mongolia showed that this model could quantitatively analyze the degradation degree , risk degree and easy - restoration degree of the grasslands under different optimizing management levels , which was of significance for applying rational measures with pertinence , and beneficial to the optimal allocation of resources during the management of degraded grassland 结果表明,通过构建退化草地优化管理模型,定量分析流域内不同优化管理等级退化草地的退化程度、危害性和易恢复性,可以有针对性地采取合理的治理措施,有利于退化草地治理中的资源优化配置。 |
| 10. | The study of different deteriorated grasslands showed , although occurring genetic differentiation and reduced genetic diversity , biodiversity in deteriorated population can still maintain a high level . additionally , it had gene exchanges with normal populations . the deteriorated grassland can restore its vegetation as normal if rational management was adopted 不同退化系列,克氏针茅种群虽发生了遗传分化,遗传多样性略有降低但仍维持较高的水平,且与正常草地间有基因流,只要采取合理的草地利用措施,减轻放牧压力,退化草地即可恢复,若采取人工补播正常种群种子,将会加快退化种群的恢复进程。 |
