NDVI在禄劝县植被变化特征分析中的应用
Application of NDVI in Analysis of Vegetation Change Characteristics in Luquan County of Yunnan Province
摘要
Abstract
Luquan County in Yunnan Province was selected as the research area.The MODIS China vegetation index synthetic product remote sensing image of Tiff in 2001-2015 was used.The NDVI value of Yunnan Province was made the statistic by ArcGIS.Then the NDVI values of each year and each month in Luquan County were obtained.On the basis of the statistical analysis,the annual,seasonal and monthly variation characteristics of vegetation index in Luquan County were described and analyzed combining the local cropping systems.The results showed that the annual mean NDVI of 2001-2015 in Luquan County had an increasing trend with the trend line slope of 0.003,which reached the highest value in 2013,and the second was in 2014.The vegetation coverage in summer and autumn was higher than that in the other two seasons.The NDVⅥ value of autumn and winter was in an increasing trend respectively,and the growth rate in autumn was greater than that in winter.The highest NDVI value in Luquan County in a year occurred in August,and the minimum value appeared in April,which was related to the vegetation growth period and withering period in Luquan County.关键词
