Abstract：Analyzing the changing characteristics and ecological environmental effects of the national spatial pattern from the perspective of the main functional areas is of practical significance for constructing a reasonable and orderly national spa-tial pattern and protecting the ecological environment.The article takes Jiangxi Province as an example,using three phases of land use data,a comparative study was conducted on the changes in land spatial structure of Jiangxi Province before and after the release of the main functional area plan(2000-2010 and 2010-2020).The ecological environment quality index and ecological contribution rate were used to quantitatively analyze the ecological environment effects of different periods.The re-sults are as follows:(1)Compared with 2000-2010,the dynamic degree of land spatial transformation in Jiangxi Province de-creased from 2010 to 2020.Its spatial agglomeration has weakened,and the proportion of high-value agglomeration(H-H)ar-eas in national key development areas has decreased from 38.04％to 30.94％.(2)The increase and decrease of spatial chang-es in different land types in Jiangxi Province showed a significant spatial negative correlation from 2000 to 2010.From 2010 to 2020,the spatial negative correlation weakened,and local spatial autocorrelation areas showed significant spatial differenc-es in various functional areas.(3)Compared with the years 2000-2010,the ecological environment quality in Jiangxi Province showed an upward trend from 2010 to 2020,with an increase in the area for improving ecological environment quality and a significant slowdown in the decline rate of ecological environment quality in national key development areas.(4)Compared to the years 2000-2010,in terms of positive ecological effects from 2010 to 2020,the types of land spatial transformation that lead to the improvement of ecological environment quality in various functional areas are more concentrated.Among them,the contribution rate of the transformation from agricultural production space to forest ecological space has increased.In terms of negative effects on the ecological environment,the main transformation is from forest ecological space to agricultur-al production space and urban production space.In the future,it is necessary to further strengthen the macro leading role of the main functional areas in the development and protection of national land space,deepen the positioning of regional main functions through the"three zones and three lines"strategy,and ensure the accurate implementation of national land space management policies.
