摘要:

选用2010年、2013年和2016年3个时相的Landsat系列卫星影像为主要数据源,以福诏高速福州至仙游路段为例,采用植被归一化指数(NDVI)对该路段建设前后(2010—2016年)6年间的植被恢复动态变化进行评价。结果表明:2010—2016年的年均植被NDVI波动于0.21~0.42之间,2010年、2016年的最大值分别为0.42和0.21;2010—2013年,由于福诏高速的建设,该路域的植被退化面积达到66.95%,生态等级为优良的比例从58.96%下降到20.35%;2013—2016年植被仅退化了16.23%,较2010—2013年期间退化的少,优良等级的比例从20.35%上升到35.08%。这与福州市近年来逐渐重视路域生态恢复密切相关。

Abstract:

In this paper,the Landsat series satellite images from 2010,2013 and 2016 are selected as the main data sources.Taking the Fuzhao high-speed section from Fuzhou to Xianyou as an example,the vegetation restoration dynamic change before and after the construction of the road section(2010—2016) is evaluated by using the vegetation normalization index.The results show that the annual vegetation NDVI fluctuates between 0.21 and 0.42 in 2010—2016,the maximum value is 0.42 in 2010,and the minimum value is 0.21 in 2016.In 2010—2013,due to the construction of Fushun Expressway,the vegetation degradation area of the road zone reached 66.95%,and the proportion of good ecological grade decreased from 58.96% to 20.35%.The vegetation degraded only 16.23% in 2013—2016,which is obviously less than that in 2010—2013.The proportion of excellent grade has increased from 20.35% to 35.08,which is closely related to the gradual attention paid to the ecological restoration of road zone in Fuzhou in recent years.

Key words: NDVI, road zone, vegetation, ecology grade, restoration
