极小种群野生植物保护研究进展与未来工作的思考.

Biodiversity conservation is one of the hottest topics all over the world. In order to rescue the most threatened plant species in the wild, to guide the China's biodiversity conservation and to serve the construction of national ecological civilization, a new concept of plant species with extremely small populations(PSESP)was proposed in China, which is attracting the widespread attention internationally in plant species conservation. In the past “13th Five-Year Plan” period, China launched the comprehensive program for rescuing and conserving PSESP. And in the coming 14th Five-Year Plan for National Economic and Social Development and the Long-term Targets for 2035 of the People's Republic of China, the rescue of PSESP is explicitly incorporated into the special aims at the conservation of important ecosystem and ecological restoration. The PSESP rescue and protection is a long-term systematic work with strong science, high technical and professional requirements. For scientifically conserving PSESP, rescue protection and system study should be given an equal weight. Undoubtedly, systematic research on the PSESP conservation is an important task to support their effective conservations. This paper is trying to systematically review the recent research works on the PSESP conservation, focusing on the surveys and assessment of the current populations or individual status(including confirmation of species taxonomic status), eco-biological characteristics, propagation techniques and genetic diversity, with the aim to find new theories and to form new ideas for the PSESP conservation. Finally, three insights into priorities for future conservation research of PSESP in China are proposed, which could be a reference for further PSESP conservation research. [ABSTRACT FROM AUTHOR]
