摘要:

极小种群野生植物大都分布范围狭窄、个体数量稀少且自然更新困难, 面临随时灭绝的风险, 迫切需要拯救性保护。极小种群野生植物这一概念自提出以来受到了保护生物学领域的广泛关注, 已成为当前中国生物多样性保护的一个热点方向。我国于2010年正式启动实施极小种群野生植物拯救保护工程, 并开展了大量的保护研究和实践。以“extremely small population*”和“plant”为检索词在Web of Science进行了主题检索, 以“极小种群”和“植物”为检索词在中国知网进行了主题检索, 对获取的的学术期刊论文、学位论文和会议论文进行了梳理。本文从极小种群野生植物种群、群落及生境调查与监测、适应性、遗传多样性、繁殖生物学、濒危机制、动态模型6个方面对近年来极小种群野生植物的理论研究工作进行了较为系统的综述。在此基础上, 从就地保护、迁地保护与种质资源保存、野外回归、人工繁育、标准化体系5个方面回顾了极小种群野生植物保护实践及取得的进展。基于极小种群野生植物保护理论与实践研究现状, 我们建议在极小种群野生植物未来保护工作中不断调整和完善保护名录, 加强种群结构的观测和预测、小种群形成和恢复机制的针对性研究以及特定物种的长期系统性研究, 同时促进这一概念在国际上的推广。希望本文能为国家生物多样性保护和生态文明建设提供参考。

Abstract

Aims: Wild Plants with Extremely Small Populations (WPESP) are plant species with high risk of extinction that are in urgent need of conservation. This concept has become a hotspot of biodiversity conservation in China since it was first proposed. In 2010, China officially launched the Implementation Plan of Rescuing and Conserving China’s WPESP (2011-2015), which initiated conservation research efforts and achieved successful progress.
Methods: We conducted a topic search on Web of Science and on China National Knowledge Infrastructure (CNKI) with “extremely small population*” and “plant” as the search terms. We reviewed the research results and achievements from academic papers, dissertations, and conference papers in order to evaluate the conservation of WPESP in China.
Results: WPESP research provides an important theoretical basis to guide conservation practice. We systematically reviewed research on the conservation of WPESP in recent years from six aspects: (1) the survey and monitoring of population, community and habitat, (2) adaptation, (3) genetic diversity, (4) reproductive biology, (5) endangered mechanisms, and (6) dynamic models. In this paper, we reviewed WPESP conservation progress from five aspects: (1) in situ conservation, (2) ex situ conservation and germplasm conservation, (3) reintroduction, (4) artificial propagation, and (5) technical regulation system construction. We also proposed several priorities for future conservation research.
Conclusions: Based on current theoretical and practical research, we propose five priorities for future conservation research of WPESP in China. We suggest that the conservation list should be adjusted and improved periodically. Researchers should highlight the observation and prediction of population structure, reinforce research on the formation and recovery mechanisms of small populations and conduct long-term systematic studies of specific species. The WPESP concept should be promoted at international levels to increase its influence. We hope this review may provide a reference for national biodiversity protection and ecological civilization construction.
