摘要 区域经济社会的快速发展加大了对自然生态系统的压力,研究区域发展与生态压力之间的时空差异特征有助于理解和解决当前日趋严峻的人地矛盾问题。本文以生态足迹作为生态压力的表征指标,在测算各省区典型年份生态压力的基础上,分析1980年以来不同发展水平区域生态压力的动态变化、空间溢出及空间均衡特征。研究结果表明:①各区域人均生态压力因发展水平不同而存在明显梯度,高水平区域的生态压力较大,低水平区域生态压力增长幅度较大;②生态压力空间溢出效应因发展水平不同而存在较大差距,随发展水平的提高而增大,低水平区域的生态空间处于"被掠夺"的境地;③区域发展与生态压力之间的空间关联特征明显,总体上处于"高度均衡"与"相对均衡"状态,但生态基尼系数有明显上升趋势,由区域发展差异引致的生态占用不公平倾向令人担忧。文章提示,高水平区域应该从资金、技术、人才等方面对中低水平区域(或资源输出区)进行合理的补偿,以降低各区域在生态空间占用方面存在的不均等性。 The development of regional economy and society has intensified the pressure on ecological system.It would be helpful to understand and solve the increasingly serious contradiction between man and the nature to study temporal-spatial characteristics of regional development and ecological pressure.Taking ecological footprint as the indicator of ecological pressure and based on estimating the ecological pressure in every province,this paper has analyzed dynamic changes,spatial overflow and spatial equalization of ecological pressure in China since 1980.The results show that: ①the ecological pressure in different regions has illustrated an apparent gradient due to development level and the pressure is higher in the higher-level regions,while the pressure in the lower-level regions has increased greatly.②there is a difference of spatial overflow in each region with the different development levels,and the lower-level regions are in a "deprived" situation.③there is an apparent spatial relativity between regional development and ecological pressure,and generally,it is in the situation of "highl equalization" or "relative equalization".But,the ecogical Gini coefficient has been increasing significantly and it is a worrying problem that regional difference has caused the unfair trend of ecological pressure.The result suggest that the higher-level regions ought to make up for what lower-regions(or resources output regions) have suffered from the perspective of capital,technology,and human resources to reduce the regional inequality of ecological footprint caused by regional differences.
