摘要:
 草原植被驱动机制研究一直备受关注。以1982-2015年内蒙古荒漠草原为研究对象，基于GIMMS NDVI3g及气象数据，采用皮尔逊相关系数、滞后系数探讨内蒙古地区荒漠草原NDVI对气候因子的滞后性。结果表明：1）荒漠草原NDVI、降水、气温和太阳总辐射年内变化都是单峰型。8月草原NDVI值达到最大，NDVI值年内变化不明显；降水也是8月达到最大；气温和太阳总辐射7月达到最大。2）从草原NDVI与气候因子的相关关系和显著相关面积占比来看，气候因子对草原NDVI影响从大到小的排列顺序为：降水>太阳辐射>气温。3）荒漠草原生长季植被的 NDVI与气候的滞后性分析表明，5-9月NDVI与降水相关关系显著，滞后时间为1个月左右。4月NDVI与1-4月的降水不显著，降水不是草地返青的主导气候因子；6-9月草原NDVI与气温成负相关，滞后时间为0~1个月。4-5月草原NDVI与气温成正相关，该季气温的回升是植被返青的关键因子；6-9月草原NDVI与太阳辐射成负相关，滞后时间为1个月。5月草原NDVI与太阳辐射成正相关，滞后时间为1个月；4月NDVI与1-4月的太阳辐射关系不显著。
Abstract:
 The driving mechanism of grassland vegetation has been widely concerned.This paper took the desert steppe in Inner Mongolia from 1982 to 2015 as the research object,based on GIMMS NDVI3g and meteorological data,using Pearson correlation coefficient and lag coefficient to explore the lag of NDVI on climate factors.The results showed that 1) the changes of NDVI,precipitation,temperature and total solar radiation presented single-peak curves in desert steppe.The NDVI value of grassland reached the maximum in August,and the NDVI value did not change significantly within a year; the precipitation reached the maximum in August; the temperature and solar radiation reached the maximum in July.2) According to the correlation between NDVI and climate factors and the proportion of significant correlation area,the order of the influence of climate factors on grassland NDVI was precipitation>solar radiation>temperature.3) The lag analysis of vegetation NDVI and climate showed that there was a significant correlation between NDVI and precipitation from May to September,and the lag time was about one month.The NDVI in April and the precipitation from January to April were not significant,and the precipitation was not the dominant climate factor for grassland turning green.From June to September,NDVI of grassland was negatively correlated with air temperature.The lag time was 0-1 month.From April to May,NDVI of grassland aws positively correlated with air temperature.The rising temperature in this season was the key factor leading to the vegetation green-up.There was a negative correlation between NDVI and solar radiation from June to September,and the lag time was one month.The NDVI of grassland was positively correlated with solar radiation in May and the lag time was one month; the relationship between NDVI in April and solar radiation from January to April was not significant.
