Historical evolution

During the spring and Autumn period and the Warring States period, Kailu County was located in Donghu; during the Han Dynasty, it was located in the northwest of Liaodong County in Xianbei at the beginning, and in Yanbei at the end.

In Sui Dynasty, it was under the jurisdiction of Fanyang Jiedushi; in Tang Dynasty, it was under the jurisdiction of songmo Dufu; in Liao and Jin Dynasties, it was under the jurisdiction of shangjingdao linhuang.

In the Jin Dynasty, it belonged to linhuangfu on Beijing Road in administration and linhuanglu in defense; in the Yuan Dynasty, it was first granted land by the king of Liao, and then it was under the jurisdiction of quanninglu; in the Ming Dynasty, it belonged to Tainingwei under the jurisdiction of wuliangha Sanwei.

During the Qing Dynasty, it belonged to the Royal territory of Arhorqin banner, East Zhalute banner and West Zhalute banner in Zhaowuda League under the control of Rehe city.

geographical environment

Location context

Kailu County is located in the west of Tongliao City, Inner Mongolia, between 120 ° 25 ′ - 121 ° 52 ′ E and 43 ° 9 ′ - 44 ° 10 ′ n, adjacent to Horqin district in the East, Wengniute Banner and aruhorqin banner in the west, Naiman Banner and kezuohou banner in the South and Zhalute banner and KeZuoZhong banner in the north. The total area of the county is 4488 square kilometers.

Geology and geomorphology

The tertiary sandy gravel and mudstone in Kailu Basin overlap the Mesozoic sedimentary range, and the Quaternary loose sediment is 208 m thick, which overlaps the Tertiary sedimentary range and connects directly with the surrounding mountain sedimentary rocks. The basement on the west side of the basin is mainly granite (R), and the basement on the east side is basaltic rock (DI). The gravel layer on the lower basement is shallow, even extinct.

structure

Kailu Basin is located in the southwest corner of Songliao plain, which is the junction of the western margin of the second subsidence zone and the northern segment of the third uplift zone of the Xinhua Xia system. Its main body is located at 42 ° 30 'to 44 ° 30' in Beiwei and 120 ° 00 'to 123 ° 30' in east longitude.

Kailu Basin is a secondary structure, which can be subdivided into three structural units: western slope zone, Lujiapu sag, jiamatu uplift, Zhezhong sag and zhedongnan uplift. The north and south mountain areas of the West Liaohe subsidence zone belong to two different tectonic systems. The southern mountainous area belongs to the northern margin of the Yinshan Tianshan EW complex structural belt (40 ° 36 ′ to 42 ° 30 ′ n), and the northern mountainous area belongs to the southern margin of the central part of the Daxinganling uplift belt of the Xinhua Xia system. The Yinshan latitudinal structural belt, which is composed of large-scale fold belts and large-scale compression and compression torsion faults parallel to these fold belts, runs across the area from south to North equidistant, and is pressed down by the subsidence belt of Xinhua system.

Lujiapu sag, the deepest part of the Neocathaysian subsidence zone, is more than 4000 meters deep. Different systems and different levels of deep faults crisscross, forming a number of blocks of different sizes in Kailu Basin, forming a special structural pattern of "Duo" shaped fault zone of compression torsion system, which is conducive to the accumulation and concentration of stress, and is an area prone to moderate strong earthquakes.

landforms

Kailu County is located in the west of the alluvial plain of the Xiliao River. The geomorphological origin belongs to the accumulation type. The flood deposition of the Xiliao River system makes the wide floodplain appear on both sides of the river. Due to the action of wind transport and accumulation, the vertical structure of sand superimposed on the flat land appears in the middle and micro terrain. The modern geomorphic outline of plain and marsh is formed. The geomorphic features of lake water accumulation in flood plain are very distinct. The terrain of the county is high in the West and low in the East, with a slight inclination from north to south to the middle. The altitude from taihekou to Xing'an township is 330-250-210 meters, with a height difference of 120 meters and an average height of 242 meters. The natural gradient is about 1 meter / km.

hydrology

Kailu County belongs to the Xiliao River Basin. Xiliao River, Xinkai River, Xilamulun River, Jiaolai River and wulijimuren river flow through the territory, with a total length of 320 km.

The area of natural paozi water in the county is 106000 mu. Among them, there are 26 places with water surface above 100 mu. Most of the natural bubble seeds are available water surface, and 13 water surfaces have been used, covering an area of 37800 mu.

According to the water quality of Xinkai River and Xiliao River, the annual average total amount of ions is 412 mg / L and 401 mg / L respectively; the annual average total hardness is 3.40 mg equivalent / L and 4.01 mg equivalent / L respectively; the annual ion runoff is 134000 tons and 129000 tons respectively; according to the water quality chemical classification (alegin classification), the annual average total hardness of Xinkai River and Xiliao River is cca1-ii and cca1-i respectively.
