摘要
引入区域生态足迹模型评价广西北部湾经济圈生态发展可持续程度,定量分析研究区域土地可持续利用状况。进一步利用灰色关联度和系统聚类分析方法,对北部湾城市群整体和个体在关联度上进行纵向与横向对比分析,划分在结构和功能上相似或互补的单位。分析结果表明,北部湾2011年的人均生态足迹赤字达到0.373hm2,说明人类对自然资源的利用已经超过区域土地的承载能力。建议实行区域合作分工制,明确各自发展方向,合理调整产业结构,调整区域内土地利用结构和功能,提高北部湾区域土地可持续利用能力。
By introducing ecological footprint model to evaluate the sustainable degree of ecological develop- ment of Beibu Gulf in Guangxi, the paper has made a quantitative analysis in sustainable usage of the regional land. The result was analyzed by using two methods named gray relational grades and cluster analysis, and this study made a comparative analysis between the whole one and its individuals in Beibu Gulf horizontally and vertically. It made a division of the units which were similar or complementary in the structure and function. This study showed that the deficit of ecological footprint was reached to 0. 373 hma/cap in 2011 ,while the regional carrying capacity of the land was outweighed by the usage of nature resources. It is suggested that it should establish a cooperative and divisional system in the regional area, determine their development direction respectively, and adjust the proportion in the industrial structure reasonably. Some adjustments should be done to the structure and function of land utiliza- tion within the area so as to improve the sustainable usage of the regional land ability in Guangxi.
