| 摘 要：【目的】研究2002—2015年蒙古高原植被短期稳定性对陆地水储量与气象要素的响应分析。【方法】利用GIMMS NDVI、月陆地水储量距平TWSA数据、气温和降水数据，引入自回归模型量化2002—2015年蒙古高原植被稳定性对陆地水储量距平值（TWSA）和气象要素的短期异常响应。【结果】蒙古高原植被NDVI与气温和降水具有较强的相关性，植被NDVI与TWSA相关性强的区域主要分布在蒙古高原中部腹地区域。几乎所有的植被类型像素都表现出强烈的恢复力稳定性，其中恢复力稳定性较强的区域分布在蒙古高原东北部、北部以及内蒙古中部；林地，草甸草原、典型草原都表现出较强的恢复力稳定性。研究区大多数地区都表现出对TWSA抵抗力稳定性不显著，仅有33.1%的植被像素表现出对TWSA显著的抵抗力稳定性，植被抵抗力稳定性显著区域主要分布在蒙古高原中部、东部以及西北部的典型草原和荒漠草原区。【结论】自回归模型可定量描述蒙古高原植被稳定性对陆地水储量和气象要素变化的响应分析，具有较好适用性；蒙古高原地区除了受降水和气温共同影响以外，陆地水储量在某些区域更能决定研究区植被生长状况。 |

| Abstract:【Objective】To study the response analysis of short-term vegetation stability on the Mongolian Plateau to terrestrial water storage and meteorological elements from 2002 to 2015.【Method】Using GIMMS NDVI, monthly total water storage anomaly TWSA data, temperature and rainfall data, an autoregressive model was introduced to quantify the effect of vegetation stability on the terrestrial water storage anomaly (TWSA) and meteorological elements in Mongolian Plateau from 2002 to 2015. Short-term abnormal response.【Results】The vegetation NDVI of Mongolian Plateau has a strong correlation with temperature and precipitation, and the areas with strong correlation between vegetation NDVI and TWSA are mainly distributed in the hinterland of Mongolian Plateau. Almost all vegetation type pixels show strong resilience stability, and the areas with strong resilience stability are distributed in the northeastern and northern Mongolian Plateau and central Inner Mongolia; woodland, meadowsteppe, and typical grassland all show strong resilience stability. Most areas in the study area showed insignificant resistance stability to TWSA, and only 33.1% of the vegetation pixels showed significant resistance stability to TWSA. The areas with significant vegetation resistance stability were mainly distributed in the central and eastern Mongolian Plateau. As well as typical grassland and desert steppe areas in the northwest.【Conclusion】The autoregressive model can quantitatively describe the response analysis of vegetation stability on the Mongolian Plateau to terrestrial water storage and meteorological elements, and has good applicability; in addition to the combined influence of precipitation and temperature in the Mongolian Plateau, some areas of the Mongolian Plateau have more terrestrial water storage. It can determine the growth status of vegetation in the study area. |
