- Abstract:
- According to the six regions of Northeast, North, Northwest, Southwest, Central and Southeast of China, the spatial and temporal distribution characteristics of Chinese urban water saving from “11th FiveYear Plan” to “13th Five-Year Plan” were analyzed from the aspects of water saving city construction, urban water saving quantity and capital investment, water use structure and efficiency, public water supply pipeline network leakage and pipe materials, reclaimed water utilization. Among them, the Southeast and North of China have become the “leaders” of urban water saving work, and have achieved remarkable results. By using the two-variable analysis method of SPSS and systematic clustering method, the interrelationships between the major factors were analyzed, indicating the importance of the synergy of factors. Meanwhile, the similarities and differences of urban water saving influencing factors for the six regions were revealed, reflecting the comprehensiveness, complexity and systematicness of urban water saving work. In view of the characteristics and potential of urban water saving work in the six regions, the key work and development prospects of each region was studied. This study also provided data support and scientific basis for the effectiveness of urban water saving work in “13th Five-Year Plan” and carrying out the urban water saving plan for “14th Five-Year Plan”.
