Quantitative Research of Water Resource Allocation Response Caused by Water Cycle System

Water resource allocation was carried out by a serious of engineering and non-engineering measures. These measures would influence region water cycle on two aspects, cycling process and cycling ways. Based on the data of Ningxia, water cycle changes in different areas caused by different water resource allocation measures were analyzed. A quantificational method about how to affect region water cycle by water resource allocation was also presented. At last, the water cycle changes happened in plain area, Yanghuang area, and south mountainous area were forecasted, that would give some special support for people to carry out water resource allocation rationally.
