Abstract:: 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.
