摘要：

利用 2001—2016年MODIS NDVI数据和气象站点资料，分析呼伦贝尔草原NDVI的时空变化特征及其对气候变化的响应。结果表明，呼伦贝尔草原NDVI整体呈上升趋势，平均倾向率为0.041·（10 a）-1，其中新巴尔虎右旗西北部、新巴尔虎左旗中部和陈巴尔虎旗西部等地增加显著；NDVI的年变化主要受降水驱动，两者呈极显著的正相关；生长季内，5月气温和5、6月总辐射与NDVI普遍呈正相关，北部草原达到显著或极显著水平，但之后逐渐转为负相关。NDVI与降水普遍呈正相关，5月下半月开始有台站达到显著或极显著水平，7月达到显著或极显著的台站数量最多，并存在明显滞后。生长季内，典型草原NDVI与降水显著或极显著正相关的台站次数明显多于草甸草原。

Abstract:

In order to study temporal and spatial variation of NDVI and its response to climate in Hulun Buir grassland, MODIS NDVI and meteorological data had been analyzed during 2001-2016.The results showed that NDVI was raising at a rate of 0.041·(10 a)-1 in Hulun Buir grassland, the northwest of Xin Barag Right Banner, the central Xin Barag Left Banner and the western of Prairie Chenbarhu Banner it increased remarkably. The annual variation of NDVI was driven mainly by precipitation, and there was a significant correlation between them. During the growth season, the temperature in May and the total radiation from May to June were positively correlated with NDVI, and some of them had achieved significant or very significant level in the northern grasslands, but later they gradually became negative correlation. NDVI was common positively correlated with precipitation, and the correlation began to reach significant level in some stations in May, especially in more and more stations in July, and there was an obvious lag. During the growth season, the number of stations with a significant positive correlation between NDVI and precipitation in typical grassland were more than that of stations in meadow grassland.

Key words: NDVI, Hulun Buir grassland, temporal and spatial variation, climate response
