村域尺度“三生”功能与生活质量感知空间格局及其关联--以江苏省扬中市为例

Spatial Pattern and Association of Production-Living-Ecological Function and Life Quality on the Village Scale: A Case of Yangzhong City, Jiangsu Province

以经济发达区江苏省扬中市为例,基于土地利用变更调查及农户抽样调查数据,利用因子分析、GIS空间分析、标准差椭圆等方法对居民生活质量与生产、生活和生态(三生)功能水平空间格局进行定量测度及关联研究。结果表明:①研究区各单一功能水平不等,空间形态差异显著;"三生"功能水平整体较低,高值区分散,低值区长江沿岸、建成区周边集聚,与生产功能高低值集聚区空间重叠度高。②扬中市居民生活质量主观感知总体为中等水平,相邻村域生活质量感知趋同,高值区集中于三茅街道及五一村、丰乐村等地,低值区呈零星散布状。③研究区"三生"功能与生活质量主观感知整体空间关联密切,局部因地域分异及公共基础设施与环境条件差异有所偏差,未来仍需因地制宜强化管理,协调区域生产-生活-生态功能关系。

In order to find out the inherent logical relationship between the functional level of "production-living-ecological" and the quality of life, taking Yangzhong City, Jiangsu Province, an economically developed area as an example, based on land use change survey and farmer sample survey data, using factor analysis, GIS spatial analysis, standarded viation ellipse and other methods to quantitatively measure and correlate the quality of life of residents and the spatial pattern of"production-living-ecological"function level. The results showed that: 1) The functional level of"production-living-ecological"in the study area was low overall, the high value area was scattered, and the low value area was clustered around the Yangtze River and around the built-up area. The functional levels of each single space was different, and the spatial patterns were significantly different. 2) The subjective perception of residents’ quality of life in Yangzhong City was generally moderate, and the quality of life percep tion had"proximity effect". The high value area was concentrated in Sanmao Street and Wuyi Village, Fengle Village, Neighbourhood Village, etc. 3) The overall spatial correlation between the"production-living-ecological"function and the subjective perception of quality of life was high.The local differences were due to region al differences and differences in public infrastructure and environmental conditions. In the future, it is still necessary to strengthen management according to local conditions and coordinate regional production-life-ecological function relations. The results of the study are expected to reflect the relationship between the functional level of"production-living-ecological"space and the perception of life quality, and provide a reference for the formulation of policies to coordinate regional development and improve people’s quality of life.
