摘要:

解析土地利用多功能远程耦合关系有助于准确把握京津冀协同发展水平,推动区域土地多功能协同可持续利用。以京津冀地区县域为研究单元,运用熵权TOPSIS法测度土地利用生产、生活和生态功能值,利用社会网络分析模型探求土地利用多功能相互关系,深层次挖掘土地利用多功能远程耦合格局。结果表明:①2010—2020年,京津冀地区土地利用多功能时空分异特征显著:土地利用生产功能有所下降,呈现西北低、东南高特征;生活功能明显提高,趋向均衡化发展的多中心态势;生态功能波动上升,“倒U形”两极分化明显。②生产功能、生活功能和生态功能突破地理邻近效应,远程耦合关系呈现明显网络结构形态,但整体网络结构较为松散。土地利用生产功能、生活功能和生态功能远程耦合网络具有小世界效应和无标度特性,权力结构呈现出明显“核心-边缘”特征。③生产功能、生活功能和生态功能远程耦合网络存在主溢出、主受益、中介人、双向溢出和孤立者5种角色类型。研究结果可为京津冀地区土地利用多功能协同提升提供参考,需注重以多点联动、优势互补为导向。

Abstract:

With the coordinated development of the Beijing-Tianjin-Hebei Region becoming an important national strategy, multi-factor cross-regional flow has formed telecoupling relationships of land use functions. Taking the counties in Beijing-Tianjin-Hebei Region as the research unit, the entropy-weight TOPSIS method was used to measure the production, living and ecological function values of land use, and the social network analysis model was used to explore the land use functions relationship and identify the telecoupling characteristics of land use. The main results are as follows. (1) During 2010-2020, the spatiotemporal differentiation characteristics of land use functions in the studied region are significant. Land use production function declines, showing the characteristics of low northwest and high southeast; living function improves significantly, showing the trend of balanced development of multi-center situation; the fluctuation of ecological function rises, and the "inverted U-shaped" polarization phenomenon is obvious. (2) Production function, living function and ecological function break through the geographical proximity effect, and the telecoupling relationships present the obvious network structure shape, but the overall network structure is relatively loose; the telecoupling networks of land use production function, living function and ecological function have the characteristics of small-world effect and scale-free, and the power structures show obvious "core-periphery" feature. (3) The telecoupling networks of production function, living function and ecological function forms four blocks through spatial clustering: there are five role types as main spillover, main benefit, mediator, two-way spillover and isolate. Therefore, telecoupling effect needs to be taken into account when formulating relevant strategies for land use functions. The Beijing-Tianjin-Hebei Region needs to focus on multi-point linkage and complementary advantages. It should play the leading and regulatory role of core counties in the network pattern, cultivate new growth poles, and ultimately achieve multi-functional synergy of land use.
