- 摘要:
- 为了对青藏高原近年来的植被变化趋势提供生态地理性差异方面的研究参考,利用MODIS MOD13Q1归一化差异植被指数资料,采用一元线性回归、空间插值、Mann-Kendall检验法和滑动t检验法等统计方法,对青藏高原地区4种生态植被类型2000-2018年的NDVI变化特征进行一系列初步研究,包括空间分布、趋势分析和突变检验等。结果表明:青藏高原植被空间上呈现东南-西北的梯度和带状分布特征,且从东南向西北递减; NDVI月变化表现为单峰变化趋势; NDVI年均值、年最大值和生长季均值的年际变化趋势存在明显的生态地理区域性差异,高寒草甸和针叶林近年来呈现减少趋势,高寒草原和高寒荒漠则明显增加; 高寒草甸在2011年存在气候突变,高寒草原仅在2007年存在均值突变,高寒荒漠不存在趋势突变,亦不存在均值突变,针叶林在2008年存在由增加向减少的趋势突变,但从其滑动t检验来看,不存在均值突变; 高原NDVI年际变化线性趋势的空间分布大部分呈现增加趋势,且从长势上看由东南向西北逐渐改善。
- Abstract:
- In order to provide a reference of eco-geographical differences for the vegetation change trend of the Qinghai-Tibet Plateau in recent years, based on MODIS MOD13Q1 normalized difference vegetation index data, this paper makes a series of preliminary research of NDVI change characteristics in four ecological vegetation types of the Qinghai-Tibet Plateau from 2000 to 2018 by using the statistical methods of linear regression, spatial interpolation, Mann-Kendall Test and Moving t-Test. The results show that the vegetation on the Qinghai-Tibet Plateau presents a gradient and zonal distribution decreasing from southeast to northwest. The monthly variation of NDVI shows a single peak trend. The interannual variation trends of the annual mean, annual maximum and growth season mean of NDVI on the Qinghai-Tibet Plateau have obvious differences in different eco-geographic regions. Alpine meadow and coniferous forest show a decreasing trend in recent years, while alpine grassland and alpine desert significantly increase. Alpine meadow shows an abrupt climate change in 2011. There is an abrupt change in the mean value of alpine grassland in 2007. Neither nor the trend mutation and mean mutation are existed in alpine desert. Coniferous forest shows a trend mutation from increasing to decreasing in 2008, but there is no mean mutation in the aspect of Moving t-Test. The spatial distribution of the linear trend of the NDVI interannual change on the Qinghai-Tibet Plateau shows an increasing trend, which stands for a gradual improvement from southeast to northwest in terms of growth.
