Feasibility Study on Urban Development in the Area of Qinwangchuan;

Effect of different green-cover patterns on soil secondary salinification in Qinwangchuan irrigated area;

The results surveying non visible faults at east and west sides of Qinwangchuan basin and the comparison of terraces of rivers in the region indicate that the basin was formed in Neogene and became a close fault basin in late period of mid Pleistocene by the compression and thrust of faults at east and west boundaries of the basin.

Water resources makes a great contribution to the development of Qinwangchuan irrigated area.

Taking the irrigation with trans-basin water diversion for Qinwangchuan Basin in Gansu Province as the studying case, a hydrodynamic model for simulation of the response from groundwater therein is established herein, and then the effects from different developing prospects on the local groundwater are analyzed.

economic ones in the Qinwangchuan basin, the region s existent capacity was discussed, the possibility of the sustainable development and based on the analysis was speculated.

Based on field experiment the benefit of growing alfalfa under regulated deficit irrigation(RDI) was analyzed primarily in Qinwangchuan irrigation region in order to obtain high yield,high quality and high efficiency.

, The emergence of the Zhenguang Prosperity and Peace and of its latter boom in economy and culture had closely been connected with the activities of the scholars in the Government of King Qin in the early Tang Dynasty.
