中文摘要	受气候变化和政策因素的影响,哈萨克斯坦是中亚地区生态退化和草畜矛盾最为突出的国家。研究哈萨克斯坦草地承载状态对认识草地生态系统对气候变化和人类活动的响应尤为重要。本研究基于哈萨克斯坦遥感数据和畜牧业统计数据,以生态系统的供给与消耗为基础,分析哈萨克斯坦草地生态系统与承载状态的格局变化。结果表明:(1)2003-2017年,哈萨克斯坦牲畜养殖数量呈现持续平稳增长的趋势,受冻害影响,在2011年数量有所减少,牲畜养殖结构空间差异不明显。(2)哈萨克斯坦草地供给量波动上升,而畜牧业生产消耗量持续增加,导致草地承载压力不断增加。(3)2003-2017年间,哈萨克斯坦整体的草地承载状态一直呈现富余状态,但草地承载压力指数呈现平稳上升趋势,草地承载压力较大的地区主要位于草地生产力低下的克孜勒奥达尔州、耕地集中的南哈萨克斯坦州和北哈萨克斯坦州,并逐渐向农牧交错区和半荒漠带推进。
英文摘要	Affected by climate change and policy factors,Kazakhstan is the country with the most severe ecological degradation and grassland conflicts in Central Asia.Therefore,studying the state of grassland carrying resources in Kazakhstan is particularly important for understanding the responses of grassland ecosystems to climate change and human activities.Based on Kazakhstan's remote sensing data and animal husbandry statistics,this study analyzes the patterns of changes in grassland ecosystems in Kazakhstan based on the supply and consumption of these ecosystems.The results show that:1) From 2003 to 2017,the number of livestock raised in Kazakhstan showed a trend of sustained and steady growth.Due to freezing damage,the scale of livestock farming decreased in 2011,but a spatial difference in the livestock farming structure was not obvious.2) The fluctuation of grassland supply in Kazakhstan has increased,while the consumption due to animal husbandry has also continued to increase,resulting in an increasing pressure on the grassland carrying capacity.3) Between 2003 and 2017,the overall grassland carrying status of Kazakhstan have been abundant,but the grassland carrying pressure index has shown a steadily increasing trend,the grassland carrying pressure is growing,and it is mainly determined by grassland productivity.The greater pressure in lower Kyzylorda state,the southern Kazakhstan state of the cultivated land and the northern Kazakhstan state has gradually expanded to include the agro-pastoral zone and the semi-desert zone.
