基于地形地貌因子的贵州省NDVI时空变化分析
|
摘要
研究以2001—2015年贵州省植被NDVI为研究对象,结合地形地貌因子,综合分析地形地貌对植被NDVI空间分布、变化特征的影响,并引入Hurst指数对变化持续性进行了探讨。研究表明:①全省植被NDVI总体一般,多位于0.5～0.6之间,整体趋势东南部要高于西北部。②高程、坡度、地貌等对全省植被NDVI影响相对较大,而坡向几乎没有影响,植被NDVI呈下降趋势的区域主要分布在高程500～1500 m、坡度较平缓的地方;高程大于2000 m,坡度在陡坡以上的,植被NDVI变化以增加为主,少有减少区域。③全省反持续性比重仍然较大,空间上主要分布在贵阳、遵义等经济发达的区域,表明这些区域植被覆盖在空间上存在一定的退化风险,在往后的开发利用过程中,需重点加大植被保护措施。
Taking the vegetation NDVI of Guizhou Province from 2001 to 2015 as the research object,combined with landform factors,we comprehensively analyzed the influence of landform on the spatial distribution and variation characteristics of vegetation NDVI,and introduced the Hurst index to discuss the variation persistence.The results showed that the vegetation NDVI of the whole province was generally between 0.5 and 0.6,and the overall trend was southeast higher than northwest.Elevation,gradient,landform and other factors had relatively greater impact on vegetation NDVI,while slope direction had little impact.Vegetation NDVI decline mainly distributed in the areas of 500 to 1500 meters high with gentle slope;vegetation NDVI mainly increased in the areas of over 2000 meters with steep slope.The proportion of anti-persistence in the whole province was still large,and it mainly distributed in the economically developed areas such as Guiyang and Zunyi,indicating that there was a certain risk of vegetation coverage degradation in these areas.In the future development and utilization process,it is necessary to focus on increasing vegetation protection measures.
