- 摘要:
- 为探究西南地区生长季植被覆盖时空变化特征以及驱动因子如何定量影响其动态变化，基于MODIS NDVI数据，通过趋势分析、变异系数、相关分析等方法研究了西南地区2000-2016年生长季植被覆盖的时空变化特征，并结合气候因子、DEM数据，分析了植被覆盖对气候与地形因子的影响程度。结果表明：西南地区近17年来生长季NDVI呈增长趋势（0.009/10 a），其中4月份增速最显著（0.029/10 a）；呈增加趋势的区域占研究区总面积71.94%，主要分布在东部与东南部区域；植被覆盖变化以较低稳定（31.15%）与中度稳定（25.36%）占主导。研究区NDVI与气温、降水的相关性在空间分布上主要以正相关为主；月尺度NDVI与气候因子的相关性高于年尺度的值；植被覆盖度与月平均气温的相关性高于其与月降水量的相关性，植被生长对降水月变化的响应不明显，对气温的响应无明显滞后效应。研究区平均NDVI在海拔大于4 000 m区域最小（0.30），在坡度0°~5°区域最小（0.37），但是NDVI的显著退化趋势则是以海拔大于4 000 m处最大（14.33%）；海拔大于4 000 m区域主要受降水控制，坡度5°~15°区域主要受气温控制；坡向对植被生长变化的影响没有海拔和坡度影响大。
- Abstract:
- In order to explore the temporal and spatial variation characteristics of vegetation cover in the growing season in southwest China and how the driving factors quantitatively affect its dynamic changes, based on the moderate resolution imaging spectrometer (MODIS) NDVI data, the spatiotemporal variation characteristics of vegetation cover in the growth season from 2000 to 2016 in southwest China were investigated using trend analysis, variation coefficient, correlation analysis and other methods, and the relationships between the NDVI with climatic and topographic factors were analyzed in combination with climate and DEM data. The results showed that NDVI in the growth season of southwest China presented the increasing trend (0.009/decade) in the past 17 years, with the most significant increasing rate in April (0.029/decade). The areas showing an increasing trend accounted for 71.94% of the total area, mainly distributed in the eastern and southeastern regions. Vegetation cover changes were dominated by low stability (31.15%) and moderate stability (25.36%). Temperature and precipitation are mainly positively correlated with NDVI in spatial distribution. The correlation between monthly NDVI and climatic factors was higher than annual values. The correlation between vegetation coverage and monthly average temperature is higher than that between vegetation coverage and monthly precipitation. The response of vegetation growth to the change of precipitation month is not obvious, and the response to temperature has no obvious lag effect. The minimum average NDVI is at an altitude of more than 4 000 m area (0.30), and at the slope 0°~5°(0.37), but significant degradation trends of NDVI is at an altitude of more than 4 000 m (14.33%). The area at the altitude more than 4 000 m is mainly controlled by rainfall, and the region at the slope of 5°~15° is mainly controlled by the temperature. The effect of slope aspect on vegetation growth is less significant than that of elevation and slope gradient.
