因應氣候變遷情境之雜草管理調適策略

Abstract

雖然有不同的發生境況，雜草乃農業生態系與農業生物多樣性一項無可迴避的主要威脅，透過自然或人為耕作傳(散)播各地，或成為一地的外來植物與入侵雜草。另一方面，在現行人類活動的模式及化石能源的使用下，氣候的變遷預料仍將持續的發展，亦將對社會經濟、生態環境及農業生產帶來複雜而多層次的影響，包括衍生雜草的管理問題。氣候快速的變遷引起的不同情境，將更加深雜草的負向衝擊、影響程度及問題的複 雜度，同時彰顯出雜草管理因應氣候變遷的動態調整與調適的重要與必要。 Even under various environmental conditions, weeds are an unavoidable threat to agricultural ecosystem and agricultural biodiversity. Weeds are widely dispersed around the globe through natural forces and human culture becoming exotic plants and/or invasive weeds of farmland. In the current modes of human activities and fossil energy use, trend of climate change is projected to continue and will bring profound effects and consequences to socio-economic status, biosystems, and agricultural production including weed management. New environmental scenarios give rise to a rapid changes of climate would further deteriorate and complicate the negative impacts of weeds, while highlighting the importance and significance of dynamically adapting and adjusting weed management strategies to cope with climate change.
