| Outline of Final Research Achievements |
The study object is to examine the wise use of land and water for establishment of sustainable irrigation agriculture with preventing a soil salinization in an arid area. The field research is carried to grasp of the agricultural water use and the relations with salinization and irrigation on the cultivated field in Turpan district, China.
As results, (a) farmers participation water management introduced in late years is effective in water distribution, (b) diffusing of well and increasing of groundwater use affect the decreasing of Karze (Qanat) discharge and (c) water quality in well is different by wells depth and location, were become clear. Then, it was confirmed that accumulating saline between soil surface and about 60cm depth occurs the salinization in the field. This reason is that sufficient water volume for leaching could not be secured because of the drip irrigation introduced by rearranging from border irrigation.
