(b) Plain
County Department of Yimeng Mountain alluvial lake plain plain as plain Lunan a Pro Tan Cang, located in the hinterland areas of the plains. Slowly from the northeast to the southwest of natural terrain is low, lower middle, roughly forming a trough-shaped irregular area of 1123.55 square kilometers, accounting for 84.7% of the total area of the county, including depression 514.84 square kilometers, the total area of 39.4%, accounting for the plain area 46.5%. In accordance with the County Soil Survey on micro-landform types, unit requirements, can be divided into post, the floodplain, along the high plains of several types of land and Xiaolaowa.
Gang Gang horizon original type relative height of the foot and the Dom Pedro V 2 to 10 meters, the slope of 2 to 5 degrees, can be divided into a small garden and a long-shaped hillock hillock and two, can be divided into loess Kong, sand Kong Kong and other types of clay. Area of 42.65 square kilometers, accounting for 3.8% of the plain area. Most of them are in the plains or river flood plains Xiaolaowa above, and mostly dating back 25 million years ago, the Tertiary red clay sand of residual material. These plains suitable for wheat, corn, peanuts, sweet potatoes and other crops, due to the short age of soil formation, sedimentary stratification evident in the barrier layer of soil, nutrient content, is an important county of grain, cotton, oil-producing areas .
floodplain mainly in the plain of the scope of Yi, Shu River levee within the terraces, beaches and Diwai the burst flooding land. PI Cang River flood diversion channel, and the territory of other similar cases are among them, but fewer. Such plain area of 108.15 square kilometers, accounting for 9.6% of the total area of the county plains, the sand on the main part of homogeneous alluvial sandy loam soil and alluvial soil heterogeneity. This type of system Yi, Shu, Wu Zhu River and Baima River alluvial rivers such as the new generation product of the Quaternary, 1.2 million years ago or so. The division of soil texture and structure type species, by the water deposition Such as near river at the fast-flowing traffic flow on the deposition of sandy soil; distant water slowly into the clay soil to deposit; and as such the construction of reservoirs and rivers burst their structure and texture of soil erosion by the river siltation, caused as Soil rule is broken, so the more complex forms of these plains, the soil by the Yi, Shu River, etc. come from the upstream alluvial Yimeng Mountain, mostly light texture of the sand, loamy sand soil or medium, less parent material itself with nutrients, formed on these parent materials of soil, although easy to cultivate, etc., but
high plains along the river, also known as the alluvial plain. This type of slope less than 3 degrees, and the relative height of the plain depressions 1 to 2 meters, can be divided into near sandy terraces and along the river to the two high-end, all along the river on both sides of the vertical distribution in the river outside the 0.5 to 3 km area. An area of 449.33 square kilometers, accounting for 39.9% of the county Plain area, of which more than 90% alluvial soil, and another part of the light soil of the paddy soil homogeneous soil types and other soil species. The type of plain also increased from Yi, Shu River and the alluvial silt from flood, surface with deep Quaternary alluvial materials, the relative height of less than 20 meters deep fertile soil, suitable for growing wheat, corn, cotton , peanuts, etc. for the county mainly grain, cotton, oil-producing areas. Because of its sandy soil species mainly distributed in the lower part of soil and clay soil of the upper, middle soil nutrient content, porosity is good, it is not suitable for cultivation of various crops, is also a landscape of settled land and the main villages of the county by.
Xiaolaowa plain can be divided into trough depression, closed depressions, inter-ridge depressions, several types of small depressions, also referred to Hejian (LU rooms) depressions. Such plains mainly in the southern Tan, and Tan-Tan in Hejian between the parts of Northridge, an area of 514.84 square kilometers, accounting for 46.5% of the county Plain area, accounting for 39.4% of the total area of the county. Plain as the most important type county, and its less than 50 meters above sea level, the relative height of less than 20 meters lower than 4 ‰, its all on the lime concretion black soil, wet soil, the Kuroshio paddy soil and most of all, and tidal Brown part of the soil species, mostly early Quaternary, that is, 1 million years ago, before the flood, lacustrine loess parent material. The formation of the soil parent material, texture, sticky, farming difficult, easy to plot flood, but the nutrient rich, high fertility potential, but Before the founding, the Yi, Shu River regularly burst, each to the flood season, a sea of such plain, known as After the founding, through the comprehensive management of landscapes Tin Lin, an important food grain producing areas.
In addition, the county is still a small mountain valley plains and other types of plain 8.58 square kilometers, accounting for only about 0.2% of the total area of the plain.

Yihe River Huaihe River, Shu River, the canal water, flows mostly from north to south, are the seasonal rivers, major rivers in the county 45, length 620.7 km. Yi River, Shuhe longitudinal County, the main channel for the transit. Second, there is sub-Shu Yi into the waterways, Wuli, the new Su River, Wu River, the Wu River flood channel, etc.; Sulu exit channel are old Mexican border river, the White Horse Creek, Shagou River, Qinghe waves, Tan New River , Liu Gou, Huang Tun River, Wong Nai ditch. After the founding, by several large-scale governance, while in the excavation of old river dredging New River, the county formed a more reasonable river drainage network layout, passengers have to undertake basic water, drainage water logging functions.
Yi River crossing the county's largest river. Lushan originated in Yiyuan County, flows through the Yishui County, Yinan County, Linyi City, and, in the county of crossing the village into the County Town Liu, Fang Zhen Wu in the re-crossing into the village of the county of Jiangsu Province, to import Luoma eastward into the sea. within the reach length of 57.14 kilometers, the average width of 1240 m bed, maximum flow 8000 m3 / s, the drainage area of 546.54 square kilometers, on both sides of dikes.
Coping county's second largest river crossing. Yishan originated in the south, through Yishui, Juxian to Linshu divided into two large Xiaoguanzhuang, the East branch of Xinshu, tributaries to the south southwest Linshu Lingnan Village, the right bank into the Tancheng County environment, Dai Ka from the left bank of the small southwest Linshu Tancheng source of rural income, line 5 km to the southwest of the village into the Shetzu Donghai County, Jiangsu Province, south 4 km to the re-entry Tancheng Guanzhuang Lu, traveling 34 kilometers to the southwest into the old Zhuang Village, Jiangsu Province Xinyi City, south to the filling into the Xinyi River estuary into the sea. Total length of 50 km within the reach of the right bank, left bank of the 39 km long, average width of 800 meters river drainage area of 612.28 square kilometers, maximum flow 5000 cubic meters / second.
Wu River in the western county, is in the canal water. Su upstream water, also called Wu Zhang River.
