中文摘要: |
快速城镇化推动了生态功能区“三生空间”格局及其功能发生巨大转变。基于金寨县2009年、2014年和2019年土地利用数据,对国土空间进行分类后采用景观格局指数、ArcGIS空间分析等方法,探究研究区“三生空间”格局及用地功能时空演变特征,并利用灰色关联度模型明确造成研究区“三生空间”格局发生变化的关键驱动因素。结果表明:研究时段内,金寨县生产、生活、生态空间景观功能格局趋于分散化与破碎化。金寨县“三生空间”分布格局在水平地域和垂直地域存在明显差异,生态空间广泛分布,生产空间主要分布在地北部、中部等地势平坦地区,生活空间零散分布于生产、生活空间中。其用地结构与功能转型变化数量显著,结构变化主要为农业生产用地与生活用地面积减少,生态空间波动变化;功能转型表现为城镇生活用地、工矿建设用地增加压缩农业生产空间,农业生产用地增加挤占绿色生态空间,同时大量农村生活用地转为绿色生态用地。相关政策、城镇化发展、产业发展及生态治理是“三生空间”格局演变的重要驱动因素。研究结果可为县域生态功能区“三生空间”协调发展提供一定思路。 |

Rapid urbanization has driven a significant transformation in the "three living spaces" pattern and functions of ecological functional zones. Based on the land use data of Jinzhai County in 2009, 2014 and 2019, the land space was classified, and the landscape pattern index, ArcGIS spatial analysis and other methods were used to explore the spatial and temporal evolution characteristics of the "San Sheng Space" pattern and land use functions in the study area, and the gray correlation model was used to identify the key driving factors that caused the change of the "San Sheng Space" pattern in the study area. The results indicate that during the research period, the landscape functional pattern of production, living, and ecological spaces in Jinzhai County tends to be decentralized and fragmented. There are significant differences in the distribution pattern of the "three living spaces" in Jinzhai County between horizontal and vertical regions. The ecological space is widely distributed, and the production space is mainly distributed in flat areas such as the northern and central regions. The living space is scattered in the production and living spaces. The number of changes in land use structure and function transformation is significant, with the main structural changes being a decrease in the area of agricultural production and living land, as well as fluctuations in ecological space; The functional transformation is manifested by the increase in urban living land and industrial and mining construction land, which compress agricultural production space. The increase in agricultural production land occupies green ecological space, while a large amount of rural living land is converted into green ecological land. Relevant policies, urbanization development, industrial development, and ecological governance are important driving factors for the evolution of the "three living spaces" pattern. The research results can provide some ideas for the coordinated development of the "three living spaces" in county ecological functional areas. |
