Abstract
The evaluation of the efficient utilization of the generalized water resources is to assess the water resources at regional/basin scale. The evaluation based on the simulation of water resources cycle reveals the hydraulic relationship among the regions,industries and sectors,whose water resources are generalized water resources,the evaluation objects are the natural ecosystem and artificial ecosystem,and the evaluation indexes include efficiency and benefit of the generalized water resources in different industries,sectors and regions. The paper divides water consumers into the high efficiency parts and low efficiency ones according to the different evapotranspiration,puts forward the generalized water resources evaluation index which includes the different users,sectors and regions of natural and artificial ecosystem,and takes Ningxia plain as the case study to evaluate the current efficient utilization of the generalized water resources in Ningxia plain.
