Loess landform tourist attractions

Loess landforms are landforms developed in loess strata (including loess-like soil). China is the earliest country in the world to study loess landforms. The following is the content of loess landform tourist attractions, welcome to read!

1. Luochuan Loess National Geological Park

Shaanxi Luochuan Loess National Geological Park Luochuan Loess Park is characterized by loess profiles and loess landforms and landscapes. It is a research center for studying mainland China and even Europe. A typical geopark of Quaternary geological events in the subcontinent.

Shaanxi Luochuan Loess National Geopark is located in Luochuan County, south of Yan'an City, Shaanxi Province, with a total area of ??5.9 square kilometers. Luochuan County is 135 kilometers away from the revolutionary holy land Yan'an in the north, and the surrounding area has a good tourism environment.

The loess landscape is formed by long-term geological erosion. Loess is a gray-yellow soil-like accumulation with a uniform texture. Large areas of loess are formed from the accumulation of wind-blown dust and sand in the Quaternary Period. The Luochuan area is a large area of ??loess platform, that is, the loess plateau. After long-term water erosion and division, the loess plateau formed a fragmented landscape with thousands of ravines. Along with various landform formation processes such as landslides, collapses, and sedimentation, the loess landscape was finally formed.

The Heimugou loess section is a comprehensive product of various geological processes in geological history. It is a true portrayal of tectonic movements and landform evolution over more than 2 million years. The loess strata in each period are fully exposed and the layers are stable. It truly records various information such as paleoclimate, paleoenvironment, paleogeography, paleovegetation and important geological events since the Quaternary. It can be used as a standard loess stratigraphic section and the Loess Plateau. Comparison with the loess layer above. Heimugou loess is clearly exposed, with continuous and complete strata, clear ancient soil layers and strong comparability. The depth of the ravine is 80 to 100 meters, and the valley slope is steep. It is eroded by precipitation and surface water, forming a unique and strange loess karst landform. It has high academic value.

2. Loess Plateau

The Loess Plateau is located in the northern part of central China. It is one of the four major plateaus in China. It is one of the birthplaces of the ancient civilization of the Chinese nation and the planet. The loess area is the most concentrated and largest loess area in the world, with a total area of ??640,000 square kilometers, spanning most or part of the seven provinces and autonomous regions of Qinghai, Gansu, Ningxia, Inner Mongolia, Shaanxi, Shanxi, and Henan. It is mainly composed of the Shanxi Plateau, Shaanxi It consists of Ganjin Plateau, Longzhong Plateau, Ordos Plateau and Hetao Plain.

The Loess Plateau is more than 1,000 kilometers long from east to west and 750 kilometers wide from north to south, including the vast area west of the Taihang Mountains in China, east of the Riyue Mountain in Qinghai Province, north of the Qinling Mountains, and south of the Great Wall. It is located on the second level of China's ladder Above, the altitude is 800 to 3,000 meters. The Loess Plateau belongs to the arid continental monsoon climate zone. The geotectonic units mainly include the northern Shaanxi Longdong Platform, the Variscan Fold Belt, the Pacific Yanshan Fold Belt, the Longxi Block, the Zhongtiao Mountain Block, the Luliang Mountain Block and the Fenwei Mountain Block. The downstream subsidence zone, etc., and the Qinling axis and the Ordos platform are the two major boundaries between the north and the south. [2-3]

The Loess Plateau is one of the areas with the most severe soil erosion and the most fragile ecological environment in the world. The terrain slopes from northwest to southeast. Except for many stony mountains, most of them are thick layers. Covered by loess and long-term strong erosion by running water, it gradually formed a special natural landscape with thousands of ravines and fragmented terrain. The landform is highly undulating, with mountains, hills, plains and broad valleys coexisting, and is surrounded by mountain systems. [2]

The Loess Plateau is an important energy and chemical industry base in China. Loess has fine particles, soft soil, and is rich in mineral nutrients. It is conducive to farming. Basin and river valley farming has a long history. Except for a few stony mountainous areas, the thickness of loess ranges from 50 to 80 meters, with the thickest reaching 150 to 180 meters. The Loess Plateau gave birth to the unique culture of the Loess, producing folk houses represented by "cave dwellings" and folk literature and art represented by Xintianyou and Ansai waist drum.
