摘要
我国北方草原是重要的可更新资源,是维护国家和区域生态安全,促进地区经济发展、农牧民增收的重要物质基础。近百年来,特别是近50年以来,在全球气候变化和人为等复杂因素的多重影响下,过牧超载与垦殖,导致草原生态系统受损严重,自然灾害频繁发生,是气候变化影响的脆弱和敏感地区。笔者兼顾多方面因素,在设定多层次体系的基础上,运用专家咨询法,筛选与气候相关性强的35个关键指标,其中敏感性指标20个,适应性指标15个,初步建立了中国北方草原区县域气候变化脆弱性评价指标体系,并对各指标的选择依据进行了描述。
Steppe area of northern China is an important renewable resources,which is the important material foundation for maintaining national ecological security,promoting regional economic development,increasing income of farmers and herdsmen.Over the past century,especially in the past 50 years,under the influence of global climate change and human factors such as overgrazing and overloaded reclamation,grassland ecosystems were damaged seriously,natural disasters occurred frequently.all of these made this area becoming a vulnerability area.Taking into account many factors,by expert consulting,we selected 35 key indicators including 20 sensitivity indicators and 15 adaptive indicators,and set up an intra-county vulnerability evaluation index system to climate changes in steppe area of northern china.
