气候变化对农药应用风险的影响

全球气候变化的影响已成为世界关注的热点。它不仅影响作物产量,还会影响农药应用风险问题,包括农药使用量、农药环境行为、毒性效应等。我国是农药生产和使用大国,农药应用风险问题受到高度关注。本文结合国内外的相关研究分析了气温升高、降雨变化以及极端天气频发对农药应用的直接影响,气候变化所引起的土地利用变化对农药应用的间接影响,为气候变化下农药应用风险评估和控制提供科学依据和参考。

Impact of climate change on application risk of pesticide

The impact of global climate change has become a hot topic in the world. It not only affects crop yields, but also affects the risk of pesticide application, including dosage of pesticide, environmental fate of pesticide, toxic effects and so on. China is a big country in the producing and using of pesticides, and the risk of pesticide application has attracted great attention. In this paper, the direct impact of temperature rising, rainfall change and frequent extreme weather on pesticide application is analyzed, moreover, the indirect impact of land use change caused by climate change on pesticide application is analyzed according to relevant studies worldwide, which provide scientific basis and reference for risk assessment and control of pesticide application under climate change.
