摘要
基于2000-2014年MODIS-NDVI时间序列数据集,探讨了贵州高原植被变化的时空格局。结果表明:研究期间贵州省植被覆盖度年际变化总体呈现上升趋势,但具有明显的时空变化。从空间分布上看,植被覆盖度的空间分布格局为东南部及北部地区高、西部地区较低。研究期间植被覆盖度较高的区域为黔东南州和黔南州,植被覆盖度较低的区域为毕节市和安顺市。高植被覆盖面积比例最大,低植被覆盖面积比例最小。2000-2010年间,高植被覆盖面积在逐渐增加,低植被覆盖、较低植被覆盖、中度植被覆盖、较高植被覆盖面积逐渐减少;2010-2014年间,高植被覆盖面积出现下降趋势,其他覆盖类型面积逐渐增加。
Based on the MODIS-NDVI time series data set from 2000 to 2014,the temporal and spatial patterns of vegetation change in Guizhou plateau were discussed.The results showed that the interannual variation of vegetation coverage in Guizhou indicated an upward trend during the study period,but it had obvious spatial and temporal changes.From the spatial distribution,the vegetation coverage of the southeastern and northern regions were high and the western regions were relatively low.The areas with high vegetation coverage were Qiandongnan Prefecture and Qiannan Prefecture.The areas with low vegetation coverage were Bijie and Anshun.The proportion of high vegetation coverage area was the largest and the proportion of low vegetation coverage area was the smallest.The area covered by high vegetation was gradually increasing,while low vegetation cover,lower vegetation cover,medium vegetation cover,and high vegetation cover area gradually decreased from 2000 to 2010.The area of high vegetation covered area decreased,while the area of other cover types increased gradually from 2010 to 2014.
