Abstract. The Yarlung Zangbo River Basin is located in the southwest border of China,
which is of great significance to the socioeconomic development and
ecological environment of Southwest China. Normalized Difference Vegetation
Index (NDVI) is an important index for investigating the change of vegetation
cover, which is widely used as the representation value of vegetation cover.
In this study, the NDVI is adopted to explore the vegetation condition in the
Yarlung Zangbo River Basin during the recent 17 years, and the relationship
between NDVI and meteorological variables has also been discussed. The
results show that the annual maximum value of NDVI usually appears from July
to September, in which August occupies a large proportion. The minimum value
of NDVI appears from January to March, in which February takes up most of the
percentage. The higher values of NDVI are generally located in the lower
elevation area. When the altitude is higher than 3250 m, NDVI began to
decline gradually, and the NDVI became gradual stabilization as the elevation
is up to 6000 m. The correlation coefficient between NDVI and
precipitation in the Yarlung Zangbo River Basin is greater than that with
temperature. The Hurst index of the whole basin is 0.51, indicating that the
NDVI of the Yarlung Zangbo River Basin shows a weak sustainability.
The emergence and spread of plasmid-associated multidrug resistance in bacterial pathogens is a key global threat to public health. It is important to understand the mechanisms of the formation and evolution of these plasmids in patients, hospitals, and the environment.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
