What is the terrain like in Zoucheng City?

Zoucheng City is located in the southwest of Shandong Province. It is a national historical and cultural city, an outstanding tourist city in China, and one of the top 100 counties and cities in terms of comprehensive strength in the country. It is known as "the homeland of Confucius and Mencius and the birthplace of culture" , the city has jurisdiction over 13 towns, 3 streets, and 2 provincial economic development zones.

The total area is 1,616 square kilometers and the total population is 1.16 million.

Zoucheng City is located in the low mountainous and hilly area of ??central and southern Shandong. The terrain is higher in the east and lower in the west, and the altitude is mostly between 200 and 300 meters.

The terrain is complex and varied.

Mountains and hills account for about 70% of the city's total area, and plains account for about 30% of the city's total area.

Mountainous areas are mainly concentrated in the east and south.

The highest peak of Phoenix Mountain is 648.2 meters above sea level.

There are many types of mountain vegetation and forestry resources, and it is the main base for the development of forestry, fruit industry and animal husbandry.

The hilly land is sandy and has good arable performance. It is suitable for the development of economic forests. It is also the concentrated production area of ??peanuts and sweet potatoes in the city.

The plain includes the Zouxi Lake East Mountain Piedmont alluvial plain, which is surrounded by mountains on three sides in the east, south and north. The soil is fertile and it is an important grain and vegetable production area.

? The geological structure within the territory is complex, and the strata are relatively complete. From the Archaean to the Quaternary, strata are developed in all stages.

There are six mountain systems in the whole territory: Changping Mountain, Ni Mountain, Lianqing Mountain, Fenghuang Mountain and Fu Mountain.

Among them, 4 are above 500 meters above sea level, with beautiful scenery; the water system is distributed in a vein shape, and the rivers include Baima River, Si River, Wangyun River, Shiqiang River, Liaohe River and Xiaoyi River. There are two major water systems, Si River and Yi River.

Provide favorable conditions for the development of agricultural production in Zoucheng City.

There are 110 large and small reservoirs in the territory, which play a good role in drought and flood control.

?Zoucheng City has a warm temperate transitional monsoon climate, with obvious continental climate characteristics, with four distinct seasons, concentrated rainfall, and synchronized rain and heat.

Spring warms up quickly, with more wind and less rain, and spring drought often occurs; summer is mostly controlled by the ocean monsoon, with high temperatures and rain; autumn is crisp and cool, but the temperature drops quickly, but autumn drought and continuous rainy weather also occur; winter is controlled by the continental monsoon , rain and snow are scarce, cold and dry.

According to statistics, the average annual precipitation over the years is 752 mm.

There is sufficient sunlight, the average accumulated temperature >0℃ is 5316.9℃ per year, the average accumulated temperature >10℃ is 4785℃ per year, the sunshine hours are 2431.3 hours, and the annual frost-free period is 202 days.

Drought, flood, dry hot wind and hail are disastrous weather in this city, which poses a great threat to agricultural production

? Due to the complex topography, strong tectonic activity and fragile geological environmental conditions , coupled with the frequent engineering and economic construction activities, the development of geological disasters is more obvious. The mountainous area in the east of Zoucheng City and the coal mining subsidence area in the west are both prone to geological disasters. There are many hidden danger points for geological disasters such as landslides, collapses, and ground collapse, and they are widely distributed. Sudden and destructive.

?The Zoucheng city magmatic rocks are mainly distributed east of the Yishan fault in the eastern part of Zoucheng city. The magmatic rocks in the area mainly include: the Cenozoic Xishan period Babuzhuang super unit, the Mesozoic Yanshan period Yinan super unit, Paleoproterozoic Luliang period Hongmen superunit, Sihaikou superunit, Aolaishan superunit, Neoarchaean Wutaishan period Yishan superunit, Neoarchaean Fuping period Nanluopo superunit, Mengshan superunit, Wanshanzhuang super unit.
