摘要:
以重庆市南岸区为研究对象，结合城市扩展、社会经济发展与生态环境之间的多元性与复杂性，在南岸区1996—2016年建成区扩展的数量及形态研究的基础上，采用改进的压力状态响应模型DPSR综合生态评价模型定量评价了城市用地扩张的生态环境效应，并识别了城市用地扩张系统与生态环境系统的主要影响因素，从小尺度、系统、动态的角度对城市扩张的生态环境效应进行了研究，以期对优化城市空间发展模式、促进城市社会生态的协调持续发展提供科学支撑。研究认为：南岸区建成区面积由1996年33.03 km2增长到2016年的122.39 km2，空间分布由最初的“西部小面积集中分布”发展为“西部成片、铜锣一线以及东部小分散”的状态，城市边界扩展明显；2000—2016年重庆南岸区生态环境效应处于中等水平，综合指数由0.36上升到0.6，但上升强度为下降趋势；回归结果显示非农业人口比重增长、经济发展是影响生态环境指数的重要因素，建设用地扩展等指标对生态环境有负面影响。
Abstract:
Taking Nan’an District of Chongqing City as the research site, combining the diversity and complexity between urban expansion, socio-economic development and ecological environment, based on the study of the number and form of expansion of built-up areas in Nan’an District from 1996 to 2016, we use the improved DPSR model DPSR integrated ecological assessment model to quantitatively evaluate the ecological environment effects of urban land expansion, and identify the main influencing factors of urban land expansion system and ecological environment system, and investigate the eco-environmental effects of urban expansion from the perspective of small scale, system and dynamics in order to provide scientific support for optimizing urban spatial development model and promoting the coordinated and sustainable development of urban social ecology. The area of construction area in Nan’an District increased from 33.03 km2 in 1996 to 122.39 km2 in 2016. and it had developed from the initial single-centric continuum in the west to the state of the west cluster area, and the small dispersion area to the east of Tongluo, and the urban boundary had expanded significantly; from 2000 to 2016, the eco-environment effect of Nan’an District was at a medium level, and the comprehensive index rose from 0.36 to 0.6, but the rising intensity presented the decreasing trend. The increases in the proportion of non-agricultural population and economic development are important factors affecting the eco-environmental index. Construction land expansion and other indicators have a negative impact on the eco-environment.
