How to evaluate the cloud seeding effect is a key issue of weather modification activities. This paper summarizes the quantitative evaluation studies of artificial precipitation enhancement in China in recent years. The concept, approach, impact factors, and disadvantages of quantitative evaluation are systematically introduced. The increment rate in every literature is studied intensively to give a brief review on the quantitative evaluation of weather modification operations carried out in China. Moreover, some aspects for development and improvement of evaluation technology are discussed in detail to provide help and advice for future cloud seeding evaluation studies.
