Rich in resources, now 25 kinds of proven mineral resources, is the national key coal-producing counties (cities), high-quality bauxite export base and limestone storage area. Superior location, convenient transportation, industrial supporting capacity. Jiaoji Railway, Ji-Qing, Ji-Wang Highway and Ji-Qing Expressway run through the east and west, 0-9 Road, Zhanglai Highway runs through the north and south; Jinan International Airport is 35 kilometers away from Mingshui. With a strong industrial base, it has formed four major industries, namely transportation equipment, machinery manufacturing, fine chemicals, food and beverage. 2008 GDP was 37.4 billion yuan, local revenue was 2.003 billion yuan, and it ranked 40th among the top 100 small and medium-sized cities in China in terms of comprehensive strength in 2008, and it was awarded as one of the top 100 small and medium-sized cities in the country in terms of investment potential, one of the top 100 cities in the country in terms of regional power and one of the top 10 economizing small and medium-sized cities in the country.
Geographic location
Zhangqiu City is located in the middle of Shandong Province, 50 kilometers east of Jinan City, 70 kilometers long from north to south and 37 kilometers wide from east to west, with a total area of 1855 square kilometers. From the point of view of geomorphology, Zhangqiu belongs to the west of Shandong Province fault block area, in the west of Shandong Province fault block area within the Tai Lu block rung, the Paleozoic strata from new to old exposed, the oldest for the Middle and Upper Cambrian chert outcrops constitute the southern cell: the Devonian system of the Middle and Upper Limestone System sand shales exposed in the area near the Mingshui, and to the north in the vicinity of the small Changbai Mountain is dominated by igneous rocks. The former easy permeability, the latter does not work, coupled with the terrain of the south high north low, groundwater convergence from south to north, in the Mingshui blocked near the head of the exposed ground, the line into the springs, so the Mingshui more sweet springs, more water.
The climate
Changqiu is a warm temperate monsoon zone of continental climate, four distinct seasons, rain and heat in the same season, spring drought and windy, summer rainfall is concentrated in the fall, mild and cool, winter snow less dry and cold. The average annual sunshine is 2647.6 hours, the average temperature is 12.8℃, the average annual precipitation is 600.8mm, the relative humidity is 65%, and the frost-free period is 192 days.
Geology
The southern part of the Ruxi uplift area, the northern part of the Jiyang depression area, is a rotational torsion tectonics Ruxi system of the outer
spinning part of the north-south and north-west compression and torsion fault development. In particular, the Wenzu fault, two discs of north-south displacement
moved 15 kilometers, so that the two sides of the fault in the topography, geology and groundwater sources and other Wan face, the formation of significant differences between east and west.
Geological formation is generally monoclinic rock formation, to block break mainly, folds are rare. The rock strata are oriented to the north-west 60° inclined
toward the north-east 30°, the inclination 7° ~ 13°. The strata of various geological eras are complete. From south to north, the mountainous region is characterized by
metamorphic rocks, limestone, shale, coal seams, and volcanic eruption rocks. The hilly valleys and alluvial plains are extensively
distributed with mudstones, freshwater tuffs in the lower part, and sand and gravel layers and various types of soils in the upper part.
Topography
Located in the northern foothills of the Taiyi Mountains, bordering the North China Plain, the Great Wall Ridge stretches to the south, and Changbaishan Mountain stands
in the east. The terrain slopes from southeast to northwest. From south to north for the mountains, hills, plains, depressions,
respectively accounted for 30.8% of the city's total surface, 25.9%, 30.7% and 12.6%. The highest peak is the Jizhu
top in the south, with an elevation of 924 meters; the lowest place is the area of Zhu Jiawa in Xinzhai Township in the north, with an elevation of 15 meters.
Climate in the middle latitude, is a warm temperate monsoon zone of continental climate. Four distinct seasons, winter and spring, less rain and snow,
Rainfall is concentrated in the summer. The average annual sunshine is 2647.6 hours; the average annual temperature is 12.8℃, 13.6℃ in high temperature year and 11.7℃ in low temperature
year; the average annual precipitation is 600.8 millimeters, generally 500-700 millimeters. Monsoon, due to the terrain
influence, reflection is not obvious, except in May to C (quiet wind) and SSW (South-South West) as the most wind direction, other months
C (quiet wind) and ESE (South-East-East) as the dominant wind direction. The relative humidity is 65% and the frost-free period is
192 days.
