基于NDVI的福建省植被变化特征分析
Analysis of vegetation variation characteristics in Fujian based on NDVI
摘要
Abstract
Remote-sensing vegetation indices from moderate resolution imaging spectroradiometer, moderate resolution imaging spectroradiometer ( MODIS ) , trendline analysis and wavelet analysis were applied to deal with the temporal-spatial dynamics of vegetation in Fujian in recent years. It was concluded that generally the vegetation coverage was good and stable in Fujian in recent 11 years, but in the population-density sea-coastal areas, rapid urbanization areas and islands there was poor vegetation. The highest value of normal difference vegetation index, normal difference vegetation index ( NDVI) appeared in August and September, and the lowest value appeared in March. Growing season and non-growing season of NDVI with the duration of 12 months within a year had the most significant variation. Annual average NDVI value in Fujian, growing season average NDVI value, and non-growing season average NDVI value tended to increase before 2003, followed by declining, and reached the lowest generally in 2005, followed by gradual increasing again. The areas where vegetation increased remarkably in Fujian were northwest Longyan, southeast Zhangzhou and central Putian, while the areas where vegetation decreased remarkably were urban Fuzhou, and sea-coastal urban areas of Putian, Quanzhou and Xiamen.关键词
