Abstract:: In order to explore the temporal and spatial changes of land use structure and function and its ecological environment effects in Shaanxi Province under the background of rapid social and economic development，according to land use classification based on leading function of production，ecology and living，we took Shaanxi Province as the case and made use of land use change/cover data in 2000，2010 and 2018 respectively by remote sensing interpretation obtained from Landsat TM. And then we quantitatively analyzed the characteristics of land functional structural and spatial transformation as well as its eco-environmental impacts. The methods discussed in the article included land use transfer matrix，index of regional eco-environmental quality and ecological contribution ratio of different kinds of land changes. The results showed that:(1)the distribution of land use types in Shaanxi Province was quite different; the production and living land mainly distributed in the Guanzhong Plain，and the ecological land mainly distributed in the northern Shaanxi plateau and the mountainous region of southern Shaanxi; among them，the ecological land area was the largest and tended to expand，while the production land area was of medium and continued to decline，the living land area was the smallest but tended to expand obviously;(2)the transfer of land use types was mainly manifested in the occupation of agricultural production land by grassland，ecological forestland and urban and rural living land;(3)the eco-environmental quality index rose slightly，and it showed a pattern of highest level in the south，low level in the middle，and higher level in the north;(4)the mutual transformation among agricultural production land，forestland and ecological grassland was the main factor affecting the change of ecological environment quality. The conversion of production land to ecological land has improved the quality of the ecological environment.
