摘要

[Objective] The research aimed to study the influence of abrupt climate variation on the vegetation based on NDVI. [Method] Based on NDVI and climate data in China during 1982-2000, by using Mann-kendall (MK) abrupt change detection method, the abrupt variations of climate and NDVI were detected. Then, the relationship between two kinds of abrupt variations was discussed. [Result] The large-area abrupt variations of monthly average temperature and rainfall happened in 1983, and the occurrence range in 1999 ...
