| 摘要: |
| 【目的】 分析陕西天华山自然保护区的地质及地貌特征，为合理规划和利用其资源提供基础依据。【方法】 根据调查分析并参考有关文献，对陕西天华山自然保护区的地质构造、地层与地貌类型进行分析。【结果】 天华山自然保护区在大地构造上属于秦岭褶皱系南秦岭印支冒地槽褶皱带。该区的地层主体部分是巴颜喀拉-秦岭地层区（Ⅶ）南秦岭地层分区（Ⅶ2）宁陕-白河地层小区（Ⅶ23）的一部分，其地貌属于秦岭山地区、秦岭南坡中山亚区的侵蚀剥蚀中起伏-大起伏花岗岩中山地貌;地貌类型主要分为山岭系统和沟谷系统，中、小型地貌甚为发育。【结论】 天华山自然保护区的地质构造为冒地槽褶皱带，地貌类型比较简单。 |

| Abstract: |
| 【Objective】 This paper analyzed the geological geomorphic character of Tianhuashan Mountain Natural Reserve and provided basis for programming and taking advantage of the resources.【Method】 This paper studied the tectonic structure,stratum and geomorphologic type of Tianhuashan Mountain Natural Reserve by site investigating and analyzing related literatures.【Result】 The tectonic structure belongs to South Qinling Indosinian miogeosynclinal folded belt of Qinling fold system.The main stratum is a part of Ningshan-Baihe stratigraphic microprovince(Ⅶ23) in South Qinling stratigraphic area(Ⅶ2) under Bayanhar-Qinling stratigraphic zone(Ⅶ).The geomorphologic region is a part of South Qinling middle mountains subregion and the geomorphic type is mainly mountain system and ravine system.【Conclusion】 The tectonic structure of Tianhuashan Mountain Natural Reserve is miogeosynclinal folded belt and the geomorphic type is simple. |
