摘要
随着中国经济的高速发展,人地关系逐渐紧张并表现为“三生”空间之间的胁迫和博弈。以江苏省为研究对象,选取2000年、2010年和2020年的土地利用数据,构建江苏省“三生”功能评价指标体系并探讨“三生”功能的时空演变特征。结果表明:(1)2000-2020年,江苏省“三生”功能整体呈现上升趋势,而生态功能在苏北地区表现为先下降后上升。(2)2000-2020年,江苏省“三生”功能地域分异特征明显。在空间角度上,生产功能、生活功能和生态功能都呈现出非均匀分布。(3)江苏省“三生”功能差异整体表现为缩小态势,但“生态”功能差异在不断扩大,苏南、苏中和苏北在“生产”“生活”和“生态”方面均存在显著差异。
With the rapid development of China’s economy,the relationship between human beings and the land has gradually become tense and manifested itself in the coercion and game between the“production-living-ecological”spaces.Taking Jiangsu Province as the research object,the land use data in 2000,2010 and 2020 are selected to construct the evaluation index system of Jiangsu Province’s“production-living-ecological”function and explore the spatial and temporal evolution characteristics of the“production-livingecological”function.The results show that:(1)from 2000 to 2020,the“production-living-ecological”functions of Jiangsu Province as a whole show an upward trend,while the ecological functions in the northern part of Jiangsu Province show a first decline and then increase.(2)From 2000 to 2020,the geographical differentiation of the“production-living-ecological”functions in Jiangsu Province is obvious.From a spatial perspective,the production function,the living function and the ecological function all show a non-uniform distribution.(3)In Jiangsu Province,the differences in the“production-living-ecological”functions as a whole are narrowing,but the differences in the“ecological”functions are expanding,and the“production”,“living”and“ecological”functions in the south,center and north of Jiangsu Province have become more and more important.There are significant differences in“production”,“life”and“ecology”in Southern Jiangsu,Central Jiangsu and Northern Jiangsu.
