Based on field experiments of the water irrigation which have been conducted in the LuanCheng Agriculture Experimental Station of Chinese Academy of Sciences, SWAP (Soil-Water-Atmosphere-Plant) model developed by Wageningen Agricultural College was used as an analysis tool. The parameters in the model were calibrated with the data of irrigation experiment. Some kinds of irrigation schedules in different flow years and certain irrigation quotas in this region were developed. The different irrigation quotas based on different irrigation schedules were simulated with SWAP model. The guidance irrigation schedule was put forward as five irrigation times in winter-wheat field and one irrigation time in the summer-corn field in median flow year. The optimal irrigation schedule would be useful for reference of water use of the farmland in this region. © 2011 Published by Elsevier Ltd. Source

Based on numerous actual data collected from long-time field investigation in source region of the Yangtze River and refering to the former research achievement, we analyzed the neotectonics movement characters in source region of the Yangtze River using the structural analysis. The results show that the tectonic motion has been very intensive in source region of the Yangtze River since the Quaternary period. Except for the vertical movement with integrity, differences, and periodical uplift, the Neotectonics Movement also shows a horizontal movement which experienced a period like Crustal shortening-nappe fold and fracture-block sliding. The whole tectonic movements shows both the successive revival and a certain reconstruction and regeneration. Overall, the Neotectonics Movement shaped the landform and Drainage pattern of source region of the Yangtze River. Source
