Changchun, located in the eastern part of the natural hilly plains to the west platform of the transition zone.Plain the larger, slightly undulating plateau, is flat, to facilitate traffic.Apart from Changchun in the eastern part of a small hilly area, most of the platform, the second Songhua River, Yin Mahe, Iraq Tonghe longitudinal Meanwhile, the two sides along the river is flat alluvial plain.Is flat, convenient traffic.Ease of natural areas in the Changchun Economic development is very beneficial.Changchun natural areas have two characteristics: first, small undulating terrain.The relative surface height difference of not more than 40-50 meters, ground slope of not more than 4 degrees to 5 degrees, is conducive to the development of urban transport.The second is that endurance is better.Changchun Geological solid basis for comparison, the endurance for 15 to 20 tons / sq m and is conducive to urban infrastructure.Surface morphologyChangchun to Siping deep fault is a division of the mountains and plains of the main structure, for the uplift in the east, west of the settlement, located in Changchun and Shenyang-long uplift in between.Geological structure of the interim decision of the Changchun types of landscape diversity, the formation of the East West low geomorphological features.Regional landscape in Changchun by the mountain landscape, and plain platform components to form a "mountain four-fifths Kong," the landscape pattern.Changchun little mountain area, about Changchun total land area of nine percent.Among them, accounting for 2.56 percent of low mountains, hills of 6.44 percent.Montenegro and the main Jilinhada Ridge.Changchun Taiwan ground only larger, the total land area of about 41 percent.Among them, 35.23 percent of the flat platform, high plateau of 5.77 percent.Elm main platform, Changchun platform, double-balcony and gifted Longquan platform.Plain largest area of Changchun, the total land area of about 50 percent.Among them, 39.4 percent of the valley plain, low-end to account for 7.5 percent, Lake plot Plain 3.1 per cent.Shuangyang main basin, the Songhua River valley plains, Lalin River valley plains, plains and valleys Yinma He Nong'an plot Lake Plain.City landforms eastern part of Changchun City in the western plains to the mountains of Taiwan on the transition.Low-lying East West, the landscape of plains and from the platform.The platform accounted for 70 percent, accounting for 30 percent plains.Different types of landscape of urban construction plays a different role of the constraints.Changchun City landscape is divided into seven district.Central high-level watershed areas.Changchun City in the southwest, the bridge is located in Kuan-ping, to the east along the northern extension.The highest point in the wide-Bridge and the West Chaoyang Bridge area, elevation 240 to 250 meters.Highland top of the watershed, is flat, respectively, on both sides of Highlands to the northwest, southeast slowly tilt.Micro-Western tilt Taiwan region.Highlands watershed in the west, in the west of the railway, textile mill north of Changchun City, elevation 220 meters.Caijiagou river flowing through the middle from the platform, the second Miao-fu, Dafangshen Reservoir, Tuen Crescent and songjiawazi, in a two nearby Fort Tonghe into Iraq.Caijiagou river wide-shallow, slow-slope, the ground than the drop of less than 5 ‰, for the complexity of the 4-5, supply of construction.Lvyuan Qu is located here, the land utilization rate is not high.Micro-ups and downs in the eastern part of Taiwan.Highlands watershed in the east, elevation 220 to 230 meters, the slope in more than 30 'to 1 ° between the complexity of the 4-6, is the town centre and railway construction area north of the location.On the three-cutting, the ground was microwave-ups and downs.First Toudaogou shallow valley.About four kilometers, Victory Park from the west side of the river, a scenic park of the victory.After the recovery path, the Kyrgyz Railway, in Changchun City, steel mills into the north of Iraq Tonghe.Second, the two Daogou shallow valley.About five kilometers, the river from the west side of First Machine Tool Plant, the formation of the North Park Scenic Area, the North Rail Park in Changchun City smelter north into Iraq Tonghe.Third, it is shallow ditch Nanhu Lake Valley, there are three origins, has a convergence of the artificial lake, formed a South Lake Scenic Area.The artificial lake, the people of the street, through the Zoological and Botanical Gardens in the east of Wing On Bridge into Iraq Tonghe.Ups and downs in southwestern Taiwan.2 watershed in the highlands, including Bangladesh and West New South ditch ditch two parts.New West Highlands watershed in the west ditch by a series of wide-shallow ditch of the Au; Bangladesh Southern Highlands watershed in the east ditch, formed by two shallow valley.Undulating terrain here Obviously, the slope 1 ° to 2 °, the complexity of 7-8, not construction.Taiwan-cutting southeastern region.NO Diao in the area, the area do not.Au-ditch here, growing, cutting more, cutting density in the 4 km / 2 kilometers above, cutting the depth of 10-15 meters, the complexity of the ground for nine, not construction.Au individual has built a ditch Tangba, irrigation and farmland near the vegetable.Northeast Valley flat plain.Iraq Tonghe River Valley in North Plains, and from flood plains to form a band, is Erdaohezai, Bali Bao location of the construction area.Iraq-bend flow development, meandering bandwidth of 600 meters, bending coefficient of 1.5, the river channel under the cut, obviously Pianyu the west side of the valley.Plain west side of a narrow, steep slopes significantly, up to 3 meters.Broad plains east, west toward the river floodplain and the gradual transition to form a band, no significant scarp, only 190 meters above sea level.Here poor drainage, and often threatened by floods, have built embankments along the river.Low-lying area, building its weak foundation, the foundation underlying the general need to reach bedrock.Light southeast cutting valley plain.Plain in southern Iraq Tonghe of the valley, slightly higher than the northern section of the terrain, about 200 meters above sea level.Surface morphology and the northern section of similar, but more low-lying river trace paste and wetlands, there are many tributaries and creeks, streams caused deep cut under 4-5 meters of Doubi Channels, has a reservoir, formed a new legislature Reservoir Scenic Area , Changchun region is the main source landscape.Monsoon climateChangchun City, a pleasant climate, has been called the "North Spring City" reputation.Changchun City in Northeast China's Songliao Plain is located in the heart of urban elevation in the 250 - 350 meters, is flat open.A continental monsoon climate, in the wet and dry climate in the district, located in sub-humid areas to the arid areas of the transition zone.East to west since the temperature increases, precipitation from east to west decreasing.The spring dry windy, hot and humid summer rainy autumn day high Qishuang, the long cold winter, with four distinct seasons, the same quarter of rain, wet and dry moderate climate characteristics, for the development and use of human nature has provided a good climate and environment.Because of its geographical location, topography and atmospheric circulation structure fit the role, has the following basic features: four distinct seasons.Spring shorter, dry windy, rainy summer hot, hot weather limited; Qishuang autumn, the temperature difference between day and night; than the long cold winter.Significant monsoon rain of the same quarter.Mongolia's winter in a strong high pressure under control, cold and dry climate.Western Pacific subtropical high summer and the regular movement of Lake Baikal, southeast of the intersection of this cold air, rich and concentrated rainfall.Strong continental climate, the temperature difference in the larger.Winter temperatures lower than the same latitudes, summer is higher than the same latitude.Climate things transition, moderate heat water.As Changchun City in Jilin Province, the eastern mountains to the west of the transition zone Songnen Plain, with the eastern mountain humid climate in the western semi-arid climate characteristics of the transition.Transitional climate so that adequate Changchun City of Light, heat conditions better than the east, and rain in the western又好conditions for agricultural production provides a good climatic conditions.Changchun City, the average temperature 4.8 ° C, the highest temperature of 39.5 ° C, the lowest temperature of -39.8 ° C, bright sunshine duration of 2688 hours.Summer, prevailing southeast wind, but also the added moisture crossing the Bohai Sea.The average annual precipitation from 522 to 615 mm, the annual rainfall in summer rainfall of more than 60 percent; hottest month (July) the average temperature of 23 ℃.Fall, continued to be a few days of sunny and warm weather, temperature greater than the spring on the wind speed.Official website: http://www.changchun.gov.cn/
