Yitong Volcanic Group

Yitong Volcanic Group

Yitong volcano group is located in Yitong Manchu Autonomous County, only 65 km away from Changchun. It is a volcanic community composed of 16 volcanoes in continuous belts, belonging to the National Nature Reserve.

Introduction to scenic spots

Yitong Volcanic Group covers an area of 765 hectares. It was established with the approval of Jilin Provincial People's Government in 1983 and promoted to the national level in 1992. Its main protected object is the unique volcanic landscape.

It attracts geologists and tourists with its precious and rare volcanic resources. Most of the volcanic mountains are composed of basalt columns with polygonal cross-section. Some of them are tower shaped, and many groups of stone towers form a unique "tower forest". Being in the tower forest is like entering a strange world of gods and monsters. The mountains are like swords, like crouching tigers, like sleeping Lions, and the uncanny workmanship of nature makes people feel awed.

Yitong Volcanic Group is distributed in the area of 600 square kilometers in Yishu graben. There are 16 volcanic domes 230-430 meters high. Their complex and changeable rock columnar joints constitute magnificent, peculiar and rare volcanic scenery and geological landscape.

The typical and unique "extrusive" volcanic genetic mechanism of the Volcanic Group is unique in China and rare in the world, which has important scientific and ornamental value.

geographical environment

The terrain of Yitong Volcanic Group reserve is flat and open, with volcanoes rising from the ground in the NE-SW direction.

The average annual temperature is 4.6 ℃, the frost free period is 140 days, and the annual precipitation is 464-835 mm.

Location of the reserve

Yitong Volcanic Group National Nature Reserve is located in Yitong Manchu Autonomous County, Jilin Province. Its geographical coordinates are 124 ° 50 ′ e to 125 ° 22 ′ E and 43 ° 14 ′ n to 43 ° 35 ′ n.

Nature Reserve

topographic features

Yitong Volcanic Group is located in the south central part of Jilin Province in Northeast China, the West and northwest of Yitong county. It is located in the area of 124o50 ′ to 126o22 ′ e, 43o14 ′ to 43o35 ′ n, Changchun City, Gongzhuling City and Yitong county.

The reserve is adjacent to Yitong county and Yidan town in the East, Jiashan Township and Aimin Township in the south, Gongzhuling and Changchun in the West and North, respectively.

The boundary of the reserve is about 40-70 km away from Changchun and about 8-50 km away from Yitong county. The reserve is only tens of kilometers away from Siping, Liaoyuan and other cities.

There are good roads or highways between the Volcanic Group and the volcanic orifices in the city, county and district, which can pass cars, and the traffic is very convenient. Yitong volcanic nature reserve is located in Yishu basin in the hilly area of Liaoji mountains on the eastern margin of Songliao plain. The distribution area of the Volcanic Group is open and flat, and the volcanic monomers are pulled up in the flat ground of the basin and distributed sporadically along the NE direction.

The area of the monomer varies from about 4 square kilometers to about 0.025 square kilometers.

Generally, the altitude is 230-430m, and the relative elevation difference is below 150m. The distance between volcanic units varies from ten to tens of kilometers.

Most of them are in the shape of hillock or cone. The top of the hill is more slippery, the slope is slower, the gully is not well developed, and the artificial quarrying damage of some hills is strong.

hydrology

There is no perennial surface water in the volcanoes of Yitong Volcanic Group. There are three rivers in the distribution area of Yitong Volcanic Group: Yitong River, Dagushan River and Xiaogushan river.

Among the three rivers, Yitong River belongs to Yinma River system, Dagushan River and Xiaogushan River belong to Dongliao river system. The river flow is generally small.

There are Erlonghu reservoir in the south, Xinlicheng Reservoir in the north, and more than 30 large, medium and small reservoirs in the middle, such as Huanxiling, Sanlian, Fanjia and Yidan.

In addition, some spring outcrops and water bubbles can be seen. The larger spring points are xijianshan spring, dongxiaoshan spring and Jinshan spring.

climate

The reserve has a temperate monsoon continental climate. The four seasons are distinct. It is windy and dry in spring, hot and humid in summer, mild and cool in autumn, and cold and long in winter.

The annual average temperature is 4.6 ℃, the average temperature in the hottest July is 22-23 ℃, and the average temperature in the coldest January is - 6-8 ℃. The annual average precipitation is 464-825 mm, and the annual precipitation days are 107.4 days. The frost free period is 138 days, with southeast wind all the year round.

soil

Most of them are leached chernozem on the flat land, alluvial soil on both sides of the river, forest soil and grass soil on the mountain. Most of the soil in the area is rich in organic matter with high utilization value.

Reserve resources

Biological resources

Biological resources are one of the resources to be developed and utilized in this area.

Except Dagushan, the vegetation of other volcanoes is not well developed.

How to effectively plant trees, lawns and precious medicinal materials to develop the biological resources of Yitong volcano group is not only related to beautifying the environment, but also related to the vital interests of human beings such as natural ecology, social environment and economic benefits.

The development of Yitong Volcano Group coniferous and broad-leaved mixed forest (including garden), medicinal plants and economic plants, such as ginseng, wumaizi and Auricularia auricula, mushrooms and so on.

The reproduction of animals with economic value (such as sable, sika deer, red deer, etc.) in the mountain forest can not only fundamentally change the natural ecology of Yitong volcano group, but also make full and reasonable use of biological resources in this area.

Scenery resources

① Landscape resources: the special volcanic dome formed by basalt magma of Yitong Volcanic Group has the characteristics that ordinary basalt volcanoes usually do not have.

Although it has no obvious lava flow and lava quilt, nor a series of craters, volcanic waterfalls, volcanic lakes and other geological and geomorphic features, it has many unique volcanic geological and geomorphic landscapes endowed by nature. It has a rock columnar joint, xijianshan columnar joint, which is similar to Wyoming's world-famous "Tower of Demons" volcano in the United States, and a unique occurrence The complex and changeable joint morphology of Moliqing mountain, Dagushan and other places, as well as rare natural landscapes such as "peacock Kaiping", "Yingzui cliff", "Lusheng cliff", "talin", "stone Peacock" and "peacock egg", constitute a splendid picture of volcanic landscape and a natural volcano museum, which are appreciated by tourists from all over the world.
