京杭大运河江苏段沿线土地生态空间差异及响应
|
摘要
土地作为人类赖以生存的物质基础,其生态状况与人类发展密切相关。京杭大运河作为世界上最长的人工运河,极大地促进其沿线地区的经济发展与文化交流,因此,在目前社会经济快速发展的背景下,对京杭大运河沿线的土地生态空间差异研究就显得尤为迫切。以京杭大运河江苏段沿线流经县(市、区)为研究区,从自然基础、污染退化、生态结构、生态建设四方面构建了土地生态状况的评价体系;在得出评价结果的基础上使用冷热点分析模型,从聚集性分析其空间差异;最后,从"全局土地生态—社会经济—大运河条件"三方面出发,定量化分析土地生态状况对各影响因子的响应程度。结果表明:研究区各要素生态状况与综合生态状况都呈现了自北向南的下降趋势;研究区土地生态呈现较显著的空间差异性,存在南北梯度与城乡梯度;研究区土地生态状况对各类影响因子响应程度不同,整体主要受到GDP与财政收入的影响,其次受到河道蜿蜒度、年均降水量、植被覆盖度的影响。
As the basis of human survival,the ecological quality of land is closely related to human development.As the longest artificial canal in the world,Beijing-Hangzhou Grand Canal greatly promotes the economic development and cultural exchange in the areas along the line.Therefore,under the current background of rapid social-economic development,it is urgent to study the spatial differences of land along the Beijing-Hangzhou Grand Canal.Based on the counties(cities and districts)flowing along the Beijing-Hangzhou Grand Canal in Jiangsu Province,we constructed the evaluation system of the ecological conditions of the land from four aspects:natural foundation,pollution degradation,ecological structure and ecological construction.Based on the evaluation results,the hot and cold spots analysis model was used to analyze the spatial differences from the aggregation.Finally,the quantitative analysis of the results was given from three aspects which incorporated ‘global land ecology,social economic and the Grand Canal condition'.The results showed that:(1)the ecological status and comprehensive ecological status of each factor in the study area presented the downward trend from north to south;(2)there was the significant spatial difference in the land ecology in the study area with the north-south gradient and urban-rural gradient;(3)the ecological status of the study area responded differently to all kinds of influencing factors.The whole area was mainly affected by GDP and fiscal revenue,followed by meandering degree of the river,mean annual precipitation and vegetation coverage.
