Today, the environmental situation in urban areas becoming polluted, people are increasingly interested in and want to live in green cities. This paper uses the satellite image Landsat 8 and the method of calculating the vegetation index (NDVI) combined with the multivariate regression analysis to study and evaluate the change of greenery area for the inner districts of Hanoi period 2013–2016. The study results show that the greenery area is strongly correlated in the central districts and the average correlation in districts with high urbanization or agricultural areas. The green tree density in Ha Noi city is quite different between the central districts and suburbs. In the suburb such as Long Bien, Ha Dong, Nam Tu Liem, North Tu Liem, Tay Ho, Hoang Mai the green tree density in the people is quite high, exceeding TCVN 9257:2012. To be specific, Long Bien district has the highest green tree density, with 134.2 m2/person up to 11 times national standards. Meanwhile, central districts such as Dong Da, Hai Ba Trung, Ba Dinh, Hoan Kiem, Thanh Xuan have very low green tree density, lower than the minimum standard of TCVN 9257: 2012. To be specific, Dong Da is the lowest green tree density with 2.5 m2/person, lower than the TCVN 9257:2012 (> 12 m2/person) to 4.8 times national standards.
