Changes in Vegetation Index and Its Influencing Factors in Saihanba Nature Reserve from 2000 to 2020
摘要
Abstract
In order to understand the variation characteristics and influencing factors of normalized difference vegetation index(NDVI)in Saihanba Nature Reserve,using MODIS NDVI data and meteorological data from 2000 to 2020,adopting regression analysis,Theil-Sen Media trend analysis,Mann-Kendall mutation test,Hurst index and contribution rate analysis,the spatiotemporal variation characteristics of NDVI in Saihanba Nature Reserve and its response to meteorological factors and human activities were studied.The NDVI variation trend in the study ar-ea was also predicted.The NDVI in Saihanba Nature Reserve shows an overall increasing trend,with regional differences in vegetation distribu-tion.The NDVI growth rate is the highest in the western region,while it shows a decreasing trend in the central region.The NDVI in the re-search area will continue its current trend in the future,with a main upward trend throughout the region,but a decreasing trend in the western region.Precipitation and temperature have a positive effect on NDVI variation in the study area,while human activities have to some extent disrupted vegetation growth.关键词
