未来气候变化下中国农业的稳定事关中国的长远持续发展,国内外气候变化研究界和农业气象研究界对气候变化对中国农业生产的影响的评估未有一致的认识。本文从农业科学角度讨论了气候变化对中国农业生产涉及的气象资源、土地资源、农业生物环境和生态系统的影响,并从作物生长和经济产量形成的角度讨论和分析了气候变化对中国种植业、养殖业不同产业行业的影响,气候变化中一些趋势性变化因不同作物和不同区域而异,例如温度和CO_2浓度变化对农业生产的影响因不同作物和不同时相而异,反之,极端性气候/天气事件对农业不同行业的生产都显得危害很大,而气候变化中区域性干旱将成为我国未来农业生产愈来愈严重的挑战。气候变化对中国农业生产的影响甚为复杂,一些气候变化因子的实际影响还存在很大不确定性。当前,定量评价气候变化对中国农业生产的影响还存在困难。 相似文献

全球气候变化的主要特征表现为气候变暖,基于这一环境下,区域气候随之也发生了
改变,甘肃河东地区处于东部季风区域,这里的气候变化无常,生态环境比较脆弱,将气象观测
材料利用起来,用于研究这一地区气候变化在农业生产方面的影响程度,可使农业朝着稳定的
方向发展。 相似文献

Mitigation and adaptation are two principle strategies for managing human-induced climate change. Agriculture plays a duet role in climate change. It has been a major source of greenhouse gases to the atmosphere. It is also one of the sectors most vulnerable to the risks and impacts of global climate change. This paper first indentified the mitigative and adaptative options and potential in agriculture, then addressed the integrated analysis of mitigation and adaptation and its benefits for agriculture. Finally, it discussed the implications to Chinese agriculture in dealing with the global climate change. 相似文献

The purpose of this paper is to document the likely impacts of climate change on China’s agriculture and the current adaptation efforts made by government and farmers.The review of literature shows that climate change will have a significant impact on agriculture,primarily through its effect on crop yields.The extent of predicted impacts highly depends on the crop,the CO2 fertilization effect assumption and adaptation abilities.Market response to the production shocks resulting from climate change will lessen the impacts on agricultural production predicted by natural scientists.On adaptation,the government’s major efforts have been in the developing new technologies,reforming extension system and enhancing institutional capacity.Farmers do adapt to climate change,but their adaptation measures cannot fully offset the negative impacts of climate change.The paper concludes and makes implications for future studies. 相似文献

China is the world’s most populous country and a major emitter of greenhouse gases. Consequently, China’s role in climate change has received a great deal of attention, whereas the impact of climate change on China has been largely ignored. Studies on the impacts of climate change on agriculture and adaptation strategies are increasingly becoming major areas of scientific concern. However, the clear warming that has been sounded in China in recent decades has not been matched with a clear assessment of the impact of climate change on China’s water resources and agriculture. In the present study, we review observations on climate change, hydrology, and agriculture in China and relate these observations to likely future changes. We also analyse the adaptive strategies in China’s agriculture. 相似文献

Agriculture is facing great challenge in meeting global food security and is expected to face even greater challenge under climate change. The overall goal of this paper is to examine how finance can be used to achieve the joint objectives of development, mitigation of and adaptation to climate change in agriculture in developing world based on literature review. The results show that agriculture is much under invested and foreign aid also has not increased appropriately to assist developing countries to maintain sustainable agriculture under climate change. There are a wide range of areas in mitigation of and adaptation to climate change that need substantial investment. Major areas and successful cases mitigation of and adaptation to climate change in agriculture that have worked in developing countries are examined. A list of areas that have worked, could work and be scaled up or transferred is identified and discussed. This study concludes that mainstreaming agricultural mitigation and adaptation into agricultural development programs, enhancing local capacity, and considering different stakeholders' needs are major experiences for successfully financing sustainable agriculture under climate change. 相似文献

Asian agriculture is responsible for two thirds of global agricultural GDP. There have been numerous studies exploring the impact of climate change on crops in specific locations in Asia but no study has yet analyzed crops across the entire continent. This study relies on a Ricardian study of China that estimated climate coefficients for Chinese crops. These coefficients are then used to interpolate potential climate damages across the continent. With carbon fertilization, the model predicts small aggregate effects with a 1.5℃ warming but damages of about USS84 billion with 3℃ warming. India is predicted to be especially vulnerable. 相似文献
