| 摘 要： | 雅安山地面积占94%,地势高低悬殊大,河流深切,水流湍急,大地构造位置跨西部地槽,东部地台。地质构造复杂,褶皱、断裂发育,岩石出露齐全。地学背景对自然景观影响明显,如地质构造影响生物、水系、泉水等景观的出现。流水的作用,在新构造运动和岩性影响下,形成美妙的峡谷;不同岩石形成不同特色的地貌景观,明显反映出岩石性质。

Natural Landscape and Geography Background in Yaan |
| |
| Abstract: | The mountainous area accounts for 94% in Yaan. There is a great difference in the height of hypsography, and stream is rapid, and the tectonics cross the west geosyncline and east platform. Geological structure is complex, fold structure and rupture structure develop well, rock exceeds variously. Geography background has deep influence on natural landscape, for example, geological structure affects the appearance of biology, water system, spring, and so on. Under the influence of new tectonics and lithology, the beautiful gorge has formed by water action and different rock has made different land from which in turn the characteristic of rock is reflected. |
