Based on on-farm observations and experiments, SWAP Model was used to analyze the seasonal variation of soil salt and impact of groundwater table on the distribution of soil salt under conditions of drainage water reuse in Bojili Irrigation District in the lower reaches of the Yellow River, and simulate the effect of supplementary irrigation by surface drainage water on crop s yield.

This paper introduces the development of reuse water at home and abroad and summed up the problems in using of reuse water in China.

One of the key solutions is water conservation and wastewater reclamation and reuse in China,which are the scientific basis to formulate the new integrated management strategy of water resources.

The status of wastewater reclamation and reuse in China is overviewed.

Therefore, there is a need for treated wastewater reuse for such purpose to mitigate urban water shortage, especially in the newly developed housing area, where a high green coverage is often required for both commercial value and living condition improvement.
