摘要:

植物是入侵生物中种类和数量最多的类群,对入侵植物开展经济成本评估可为后续风险管理和相关政策的制定提供参考依据。本研究基于InvaCost数据库评估获得了1970-2017年全球入侵植物的经济成本,研究结果表明:1)入侵植物的保守经济成本为1943.65亿美元,年均40.49亿美元,其中,直接经济损失达1004.68亿美元,占比为51.69%;2)在64个国家和地区中,美国的经济成本最高,其次为澳大利亚,我国208.31亿美元(1407.07亿人民币)排名第三。凤眼莲是全球最昂贵的入侵植物种类,其危害所产生的成本高于排名5~10名的入侵植物成本之和;3)过去的近50年里,入侵植物的经济成本呈上升趋势,模型测算2017年入侵植物的可能成本为34.38亿~104.52亿美元,最高置信值为77.25亿美元。本研究有助于加深对入侵植物危害严重性的客观认识,可为我国开展更为积极的入侵植物治理提供科学依据。

Abstract:

Among invasive species, plants comprise the most diverse and numerous biological groups. Assessing the economic cost of invasive plants is an important part of risk management and is essential for the development of policies for control or eradication. In this study, based on the InvaCost database, we assessed the economic costs of global invasive plants from 1970 to 2017. The main results were as follows: 1) The conservative economic cost of invasive plants from 1970 to 2017 was 194.365 billion U.S. dollars (USD), 4.049 billion USD per year on average, of which the direct economic loss amounted to 100.468 billion USD, accounting for 51.69% of the total. 2) Among 64 countries and regions, the United States has borne the highest economic costs, followed by Australia, and China ranks third with costs of 20.831 billion USD (equivalent to 140.707 billion RMB). Notably, Eichhornia crassipes has been the most expensive invasive plant species globally, with the costs of its damage exceeding the combined costs of invasive plants ranking 5th to 10th. 3) Over the past five decades, the economic cost of invasive plants has shown an upward trend. Model estimates suggest that the possible cost of invasive plants in 2017 ranged from 3.438 billion to 10.452 billion USD, with the highest confidence value being 7.725 billion USD. The results of this study contribute to a deeper understanding of the severity of invasive plant threats and provide a scientific basis for more proactive invasive plant management in China.
