| Abstract: | The global 1km resolution NDVI 10d from the USGS data center is unloaded directly from the internet to compose NDVI information, and 5 monitoring points in paddy field and 6 monitoring points on dry land are selected from the southern, central and northern part of Guangxi to study the monthly changing characteristics of their NDVI The results shows that the monthly change of NDVI has a close relation with the growing change of crops, hence NDVI information may be used to develop the remote sensing monitoring by satellite for crops growing and agricultural meteorological disaster |
