In this paper，Changchun urban land from 2009 to 2018 was selected as the research object． From the aspects of urban land use scale and urban land structure，the land use dynamic degree，information entropy and equilibrium degree of land use structure were used to analyze the evolution characteristics of urban land in Changchun from 2009 to 2018． The results showed that: ① Compared with other cities in the province，the total amount of urban land use and the average annual growth rate of Changchun were significantly higher． ②The urban land use
in Changchun City showed a slow growth trend． Except for other land types，the area of all kinds of land use increased，among which the industrial land grew the fastest． ③The result of information entropy showed that the land
use type structure in Changchun gradually tends to be stable． ④The area of parks and green space was too small，its proportion needs to be improved． ⑤The per capita land use area of Changchun was quite different，especially
for parks and green space． Except Nanguan District，which met the national standard，the per capita area of parks and green space of other districts was relatively small．
