摘要: 从基于风险管理应对气候变化的基本理论框架和气候变化对我国自然保护区管理的挑战出发,明确了自然保护区气候变化风险的涵义,并以达里诺尔自然保护区鸟类及其赖以生存的水体、草地、林地、沼泽地生境为研究对象,对达里诺尔自然保护区气候变化风险及其变化趋势进行评估和预测.结果表明: 1997—2010年,达里诺尔自然保护区及其水体、草地、林地、沼泽地生境的气候变化风险均呈明显的波动性变化趋势,1999、2001、2005、2008年保护区及其4类生境和2002、2004年沼泽地生境均处于风险状态;与2010年相比,情景A、B、C下2020、2030年保护区及其4类生境的气候变化风险均有所增强;各类生境的气候变化风险存在显著差异,其中,沼泽地生境的气候变化风险较为突出,与其对气候变化的敏感性和丰富的鸟类分布密切相关;人类对水资源、草地资源的过度利用会加剧气候变化对自然保护区的不利影响及其对应的生态风险.总体上,气候变化风险在达里诺尔自然保护区已经显现,气候变化风险管理有助于保持并增强自然保护区的生物多样性保护功能.

Abstract: According to the theoretical framework of addressing climate change based on risk mana-gement and the challenge to nature reserve management under climate change, climate change risk of nature reserve was analyzed and defined. Focus on birds and water habitat, grassland habitat, forest habitat, wetland habitat in Dalinuoer Nature Reserve, risk assessment method of nature reserve under climate change was formulated, climate change risks to Dalinuoer Nature Reserve and its habitats were assessed and predicted. The results showed that, during the period from 1997 to 2010, there was significant volatility in dynamic changes of climate change risks to Dalinuoer Nature Reserve and waterbody, grassland, forest, wetland in the region, Dalinuoer Nature Reserve and its habitats were in status of risk in 1999, 2001, 2005 and 2008, wetland habitat was also in status of risk in 2002 and 2004. Under scenario A, B and C, climate change risks to Dalinuoer Nature Reserve and waterbody, grassland, forest, wetland in the region would be more serious in 2020 and 2030, compared with the 2010 level. Climate change risks to different habitats were different significantly, with most serious climate change risk to wetland habitat due to its sensitivity to climate change and rich bird resources. The effect of climate change on nature reserve and related risk would be aggravated by excess utilization of water resource and grassland resource. As climate change risks had appeared in Dalinuoer Nature Reserve, risk management associated with climate change could greatly help to maintain and enhance biodiversity protection function of nature reserves.
