摘要

[目的] 分析江西省2004-2017年间土地利用多功能状况，为区域土地持续利用提供支撑。[方法] 构建评价指标体系，基于熵值法确定各指标权重，运用TOPSIS模型综合评价了江西省土地利用多功能变化状况，并采用障碍度模型剖析了主要限制因素。[结果] 2004-2017年江西省土地利用综合功能变化动态度为297.90%，经济功能、社会功能和生态功能变化动态度分别为224.37%，207.14%，2 021.61%；生态功能障碍度逐年下降，经济功能障碍度波动上升，2010年之后主要障碍因子有综合恩格尔系数、产业结构、经济密度、人均GDP、废水排放强度、人均水资源和城镇登记失业率等。[结论] 江西省土地利用功能总体呈现增长变化趋势，但各项功能变化有所差异，其中土地利用生态功能变化最大；土地利用功能实现从经济社会型向生态社会型转变；不同阶段限制土地利用功能发挥的因素有所差异，目前主要为经济障碍因子。

Abstract

[Objective] The multifunctional land use in Jiangxi Province from 2004 to 2017 was analyzed to support regional sustainable land use.[Methods] An evaluation index system was developed

and the multifunctional changes of land use in Jiangxi Province were measured using the TOPSIS model based on the entropy method. The obstacle model was used to analyze the main restrictive factors.[Results] The dynamic degree of land use comprehensive function change in Jiangxi Province from 2004 to 2017 was 297.90%. The dynamic degrees of economic function

social function

and ecological function were 224.37%

207.14%

and 2 021.61%

respectively. The degree of ecological dysfunction decreased

and the degree of economic dysfunction increased year after year. After 2010

the main obstacle factors were the comprehensive Engel's coefficient

industrial structure

economic density

per capita GDP

wastewater discharge intensity

per capita water resources

and urban registered unemployment rate.[Conclusion] The overall function in Jiangxi Province shows a steady upward trend. However

changes varied between the functions

and the changes in the land use ecological function were the largest. The land use function demonstrated the transition from an economic society to an ecological society. The factors that limit the land use functions vary at different stages

and the main limiting factor is currently economical.
