摘　　要：A Logistic equation gray prediction model was established for prediction of reuse and reclamation rate of urban sewage in Ningxia.Based on the data of reuse and reclamation of urban sewage in Ningxia in 2006-2013,it analyzed and predicted the development trend of reuse and reclamation of urban sewage in the whole region of Ningxia. The prediction results indicate that: according to the current development trend,the reuse and reclamation rate of the whole region of Ningxia has become close to saturation,the development space is limited,there is a huge gap with the planned objectives,thus it is required to actively adjust the development strategies. On this basis,the main limiting factors affecting the reuse and reclamation of urban sewage in Ningxia were determined by analytic hierarchy process( AHP) method,in order to provide a reference for the rapid development of reuse and reclamation of urban sewage in Ningxia.A Logistic equation gray prediction model was established for prediction of reuse and reclamation rate of urban sewage in Ningxia.Based on the data of reuse and reclamation of urban sewage in Ningxia in 2006-2013,it analyzed and predicted the development trend of reuse and reclamation of urban sewage in the whole region of Ningxia.
