- 摘要:
- 为了明确区域“三生”功能结构特征和空间演变规律,实现国土空间精细化分区管理,促进“三生”功能协作共赢和国土空间可持续发展。以土地利用多功能性为基础,通过GIS空间可视化方法,定量识别了重庆市江津区2009年和2017年的“三生”功能演变特征,并总结提炼了江津区“三生”功能变化模式及优化策略。结果表明:2009—2017年,江津区“三生”功能增加近一倍,以生产功能和生活功能为主; 生产功能以工业供给功能为主呈明显扩张态势,生活功能以社会保障功能为主围绕两大核心组团聚集区显著扩张,生态功能整体无明显变化; 江津区“三生”功能变化模式可划分为高丘整体功能增强型、浅丘生产—生活增强型、高丘生活—生态增强型、中丘生活—生态增强型、中丘生产—生活减弱型、浅丘生活—生态减弱型6种类型。总体来看,受经济建设和人为干扰因素影响,江津区“三生”功能存在明显不平衡性,北部和中部区域开发迅速且潜力较大,生产功能和生活功能显著增强,而南部相对滞缓,出现零星的“三生”功能增强。
- Abstract:
- In order to clarify the regional ‘Sansheng' functional structural characteristics and spatial evolution patterns, realize refined regional management of land space, promote ‘Sansheng' functional collaboration and the sustainable development of land space, based on the multi-functionality of land use, the research quantitatively identified the characteristics of the ‘Sansheng' function evolution in Jiangjin District of Chongqing in 2009 and 2017 through the GIS spatial visualization method and summarized the pattern and optimization strategy of ‘Sansheng' function change in Jiangjin District. The results show that the function of ‘Sansheng' in Jiangjin District nearly doubled from 2009 to 2017, with production functions and life functions as the main functions; production functions with the industrial supply function as the main trend showed a significant expansion, and life functions with the social security function as the gathering area around the two core clusters had expanded significantly, and the overall ecological function had not changed significantly; the ‘Sansheng' function change pattern in Jiangjin District could be divided into six types: high hill and overall function enhancement, low hill and production-life enhancement, high hill and ecological enhancement, medial hill and ecological enhancement, medial hill and production-life weakening, low hill and ecological weakening. In general, due to economic construction and human disturbance, the ‘Sansheng' function in Jiangjin District was obviously unbalanced. The northern and central regions had developed rapidly and have great potential, and the production and living functions had been significantly enhanced, while the south had been relatively slow with the appearances of sporadic ‘Sansheng' function enhancements.
