概括

在中国的生物入侵是昂贵的,入侵性外来物种 (IAS) 每年花费数十亿美元. 贸易增加加剧了这一问题,突出了加强管理战略的迫切需要,以保护可持续的环境.

科学领域:

生态生态学生态生态学
环境经济学环境经济学
保护生物学保护生物学

背景情况:

中国面临着与贸易量增加相关的越来越多的生物入侵.
对中国的外来入侵物种 (IAS) 进行全面的经济成本评估很少,这阻碍了可持续的环境增长.
生物入侵对全球生物多样性和生态系统服务构成重大威胁.

研究的目的:

估计中国IAS的经济成本.
为明智的政策和管理提供IAS经济影响的全面评估.
为了比较中国的IAS成本脆弱性与其他国家.

主要方法:

利用了一个全面的数据库,编译了新的搜索短语,以识别和量化IAS经济成本.
分析了1973年至2022年的数据,区分了总和可靠的数据估计.
将发现与现有数据库进行比较,例如全球入侵成本数据库 (InvaCost).

主要成果:

中国是继美国之后,第二个在经济上最容易受到IAS影响的国家.
累计的IAS成本达到31246亿美元 (2017年) 的总数据和425.08亿美元的可靠数据.
损害成本明显超过管理成本 (184倍可靠的数据).
来自北美的IAS给中国带来了更高的成本.

结论:

由于IAS,中国承受着巨大的经济损失,需要增加对入侵管理的投资.
森林和东南沿海地区特别容易受到IAS的影响.
有效的管理策略对于减轻中国生物入侵造成的经济和环境后果至关重要.

Threats to Biodiversity

Threats to Biodiversity

There have been five major extinction events throughout geological history, resulting in the elimination of biodiversity, followed by a rebound of species that adapted to the new conditions. In the current geological epoch, the Holocene, there is a sixth extinction event in progress. This mass extinction has been attributed to human activities and is thus provisionally called the Anthropocene. In 2019 the human population reached 7.7 billion people and is projected to comprise 10 billion by...

Biological Methods for Microbial Control

Biological Methods for Microbial Control

Biological agents offer an effective means of controlling microbial growth by leveraging natural processes like predation, competition, and the secretion of antimicrobial substances.Predatory bacteria such as Bdellovibrio species target and kill pathogens like Salmonella and E. coli. They are widely used in poultry farms to control infections. Myxococcus species help combat plant-pathogenic fungi. These naturally occurring predators serve as eco-friendly alternatives to chemical pesticides and...
