Abstract

Accurately optimizing the ecological security pattern is of great significance for promoting regional sustainable development. Based on the viewpoint of "factor-structure-function" in system theory,this study constructs a comprehensive evaluation index system to measure the ecological security of Poyang Lake Urban Agglomeration,and analyzes its change characteristics from different scales and the optimization problems in the process of spatial planning and economic zone division of this region. The results show that: 1) From 2000 to 2020,the ecological security pattern of Poyang Lake Urban Agglomeration changes obviously with an overall downward trend. At the same time,the ecological security pattern of Poyang Lake Urban Agglomeration showed a fan-shaped regional structure at the patch scale,and the ecological security pattern of Poyang Lake Urban Agglomeration showed a ring structure at the county scale. 2) Based on the patch scale,the optimization results of ecological security pattern of Poyang Lake Urban Agglomeration are more refined,which mainly reflects in the focus and concentration of ecological security risk areas,and provides clear direction for ecological security early warning areas. 3) The optimization results at the county scale are more specific and simplified,describing the regional economic development trend as follows: districts of Nanchang City-Gao 'an City-Zhangshu City-Fengcheng City in southwest direction,districts of Nanchang City-Yugan County-Yujiang District-districts of Yingtan City in southeast direction,districts of Nanchang City-Jiujiang City-Hukou County.
