The main measures to solve the uneven time distribution of water resources are: building reservoirs; (b) Inter-basin water transfer; Artificial rainfall; And (d) a large flow of water.

Analysis of test questions: The distribution of water resources in China is affected by precipitation, with more distribution in summer and autumn, less in winter and spring, and great interannual changes. In order to solve the problem of uneven spatial distribution, water can be transferred from water-rich areas to water-deficient areas by means of inter-basin water transfer, so as to balance the spatial distribution of water resources and make more rational use of water resources.
