With the acceleration of global sustainable development, the shortage of water resources especially the city has become the focus of attention in all countries since water is the key to build a resources-saving ecological city. The article improved the existing "rain garden" project and replenished the purification of the rain in order to realize the urban water cyclic utilization ,through recycling rainwater, which can manage rainstorm effectively , improve the urban water cycle system, as well as supply urban irrigation and underground water. Besides, the combination of urban landscape and stormwater management system, if widely accepted, will not only improve the urban water problem, but also improve the urban environment, alleviating the urban heat island effect and improving the local climate. It can shape a new resources-saving ecological city and then realize the sustainable development of resources.

<p>Understanding the impacts of human regulation on development and recovery characteristics of hydrological drought is crucial to detect the relationship between hydrological drought and the regional water cycle system. In this study the standardized streamflow index (SSI) which based on the observation and SWAT simulated runoff data were used to represent the hydrological drought under human disturbed and naturalized scenarios, respectively. Furthermore, the hydrological drought events under each scenario was divided into the development and recovery stages by the run theory. Comparing two scenarios under the stage Ⅰ (1980-1989) and stage Ⅱ (2007-2016), the human disturbed scenario presents a more severe hydrological drought than the naturalized scenario at stage Ⅱ. Our study further found that the reservoir operation was the irreplaceable factor that affected hydrological drought development and recovery in the study area. The reservoir has the strong ability to alleviate the long-duration hydrological droughts, however, the recovery ability of drought has been weakened. To be noticed that though the water intake from the river by the reservoir has been reduced, the drought alleviates ability of the reservoir still become weaker than prototype after working for 30 years. Therefore, as time goes on the effects of reservoir will become progressively more important. The results of our study could be a hint for policymakers and stakeholders to enhance the drought early warning and forecasting system to optimal reservoirs’ management at semi-arid areas.</p>

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.
