Diversion Water Channel Engineering Construction And Organization Of Saline Uncultivated Land Transformation In Daan Irrigation Area

Daan irrigation area is located in the right bank of Nen river downstream of western of Song-Nen plain, which is in the middle part of the city of Daan in Jilin province. It belongs to ancient channel of Nen river. At the same time, it is also the core area of saline soils in the west of northeast China. Under climate change and man-made unreasonable use of the dual factors action, ecological environment of the region is deteriorating.Farmland,wetlands,grasslands and reed have changed originally part of the saline into a comprehensive of it. Degree of salinization converts from mild degree to severity quickly.The paper aims at present situation of saline uncultivated in Daan irrigation region, on the basis of investigation and survey, constructing the diversion water channel to improve the situation is determined. This paper introduces in detail the diversion water channel engineering overall layout principle, basis and layout details. In the engineer, how to conduct field management, engineering surveying control, construction methods and how to conduct quality control; the measures of environmental protection. Combined with the construction process of the diversion channel engineering and the benefits after the completion of it, irrigation area of how to reconstruct the right conclusion and rational Suggestions are given about transformation of the irrigation saline uncultivated.After the project of the ancient river irrigation of Daan is carried out, the large rice base,artificial grassland pasture base,Irrigation reed base and efficient breeding base will be formed in the west of northeast China. Relying on these material production base, powerful rice processing, livestock processing, aquatic products processing will be formed, and bringing the rise of industry, forming grade and efficient modern structure of agriculture and industry.
