Abstract: Based on the data of captive grey crowned crane（Balaerica regulorum） population in China in 2018, with SPARKS v1.66 and PMx v1.2 the demographic and genetic analyses of population were conducted. The results of pedigree analysis showed that, as of December 31, 2018, there were 332 captive grey crowned crane maintained at 41 institutes in China. There were 16 founders whose numbers of descendants and contribution values were uneven. Although the genetic diversity of the population was 85.97%, the development trend over past 30 years indicated the population genetic diversity would decline continuously. The models predicated that after 100 years the number of population wouldn^,t reduce a lot but the genetic diversity would decline to 78.80%. Aiming to increase the number of captive gray crowned crane population and promote the healthy development of the population, some suggestions are put forward, such as improving the individual mark; Conducting sex identification for individual of unknown sex; Increasing breeding opportunities of potential foundersby encouraging inter-institutional cooperation; Improving environmental conditions; Avoiding possibility of hybrid offspring.
