| 1. | Study of hydrosphere , atmosphere and biosphere environments in dabashan mountain 大巴山区生态环境研究报告二 |
| 2. | Status quo and protection programme on daba mountain nature reserve in chengkou 城口大巴山自然保护区现状及保护措施 |
| 3. | High resolution sequence stratigraphy of the lower shaximiao formation in the foreland basin of micang - daba mountain 大巴山前陆盆地下沙溪庙组高分辨率层序地层学特征 |
| 4. | It was shown that there are 247 species ( including varieties and forms ) , 76 genera and 34 families of pteridophytes in dabashan mountain 结果表明,大巴山具有蕨类植物34科76属247种(包含变种和变型) 。 |
| 5. | And its special tectonic conditions contribute to the development of the deep - thick - incompact slopes growing in badong formation 三峡库区位于大巴山弧形构造带与八面山弧形构造带的接合部,构造变形强烈,构造样式多样。 |
| 6. | Dynamic and thermal effect may also play an important role . results show that positive perturbation of potential vorticity in the lower layers which is pro 4地形动力作用的影响表明: ( l )大巴山的各部分对降水的影响都很大,尤其是大巴山西部山脉影响最大。 |
| 7. | In 1990 2005 , a field survey of dabashan mountain was conducted , the specimen of pteridophytes collected in the survey were identified and the data about the specimen were statistically analyzed 摘要于1990 2005年对大巴山进行了野外考察,并对所采集的蕨类植物标本进行鉴定及资料统计分析。 |
| 8. | Dryopteridaceae , polypodiaceae and athyriaceae are the three dominant families in dabashan mountain , containing 113 species , which account for 45 . 75 % of the total of the species in the mountain 鳞毛蕨科、水龙骨科和蹄盖蕨科为大巴山蕨类植物区系中占优势的3大科,共有113种,占总种数的45 . 75 % 。 |
| 9. | Of the temperate elements , east asia elements and china - endemic elements significantly dominate accounting for 84 . 36 % of the total of the species in the mountain , which indicates that dabashan mountain belong to china - japan sub zone of pteridophytes 在温带成分中,东亚成分与中国特有成分显著,共占总种数的84 . 36 % ,表明大巴山应属于中国日本蕨类植物亚区。 |
| 10. | In the end , i discussed the formation and evolution character of long sequence cycles , which had close relation to asynchronous thrust action of longmen mountains and micang - daba mountains 详细讨论了短期、中期和长期旋回层序的结构类型、沉积序列、叠加样式和分布模式,最后探讨了长期旋回层序的形成、演化特征以及与龙门山和米仓山?大巴山两构造带非同步逆冲推覆作用的关系。 |
