气候变化对鲑鳟鱼类栖息环境及相关生物学的影响

鲑鳟鱼类作为对温度和周围环境比较敏感的冷水性鱼类，气候变化尤其是全球温度升高引起环境的相关变化对其影响明显。本文针对国内外有关气候变化对鲑鳟鱼类栖息地及相关生物学影响的研究情况，先从从栖息地环境方面阐述了气候变化对水生生物的影响，又从温度、CO2浓度、降雨量及酸雨的增加、紫外线辐射增强和鱼病的传播等方面探讨气候变化对鲑鳟鱼类生物学方面的影响。同时指出目前研究中存在的地域局限性和缺乏评价标准的相关问题，并就存在的问题给出建议，提出了今后重点关注和尚待研究领域。

Impacts of Climate Changes on Habitat Environment and Correlative Biology of Salmons and Trouts

Salmons and trouts are fishes that are sensitive to the temperature and the environment, the impacts of climate change on salmons and trouts especially the increased temperature arouse the change of environment impact salmons and trouts is obvious.This paper reviews the scientific literatures about the impacts of climate changes on salmons and trouts, reviews the impacts of climate changes on aquatic organisms in terms of habitat environment,then reviews temperature, change in C02 concentration, change in precipitation and acid rainfall, the change in the increased UVB radiation and the disease of salmons and trouts. This paper finds some existed problems such as the research blank,zone limitations,lack of estimate model and give some advices about the future research.
