摘要:

划定“三线”(生态红线、城市开发边界、基本农田保护红线)是构建城市生产、生态、生活空间格局和实现“多规合一”的关键。但在实际工作中,“三线”由不同部门依据不同准则划定,在空间上往往存在冲突。本文以武汉都市发展区为例,从图斑层面探讨“三线冲突”的类型与表征,并分别采用空间格局分析和相关分析法研究“三线冲突”的空间格局特征和区域条件对其影响。研究结果表明:①武汉都市发展区内“三线冲突”以生态—耕地冲突和生态—城市冲突为主,城市—耕地冲突面积较小;②生态—耕地、生态—城市和城市—耕地冲突热点分别集中于都市发展区边缘、都市发展区内部和城乡过渡带,呈圈层分异的特点;③区域条件的6个指标对3类“三线冲突”子类型冲突强度的影响因素各不相同。研究结论为:一是“三线冲突”强度可以用“三线冲突”强度指数(TLCI)表征;二是空间自相关分析、梯度分析、景观格局分析法可以很好地刻画“三线冲突”空间特征;三是对“三线冲突”的自然—人文驱动机制的研究有待进一步完善和深化。本文有助于从城市空间视角加深对“多规冲突”问题的理解,识别“三线冲突”的自然—人文驱动因子,为实现“多规合一”提供理论支撑。

Abstract:

Delimiting ecological protection redlines, basic farmland protection zones, and urban growth boundaries is particularly crucial in coordinating urban land use and implementing the "integration of multi-planning." The purpose of this article is to explore the concept, spatial pattern, and influencing factors of "three lines" conflict at land parcel level, and to improve the theoretical framework and analytical methods of "multiple plans conflict" and "multiple plans integration." First, the connotation of "three lines" and "three lines" conflict are clarified by analyzing the essence of land use conflict and the three lines conflict index (TLCI) was constructed to characterize the intensity of the "three lines" conflict. A spatial overlay operation is performed on the "three lines" using ArcGIS software to produce the spatial distributions of "three lines" conflict of Wuhan City. Then we analyze the spatial pattern of three "three lines" conflict using a host of spatial pattern analysis methods (including spatial autocorrelation analysis, gradient analysis, and landscape pattern analysis). Finally, we identify the influencing factors of "three lines" conflict from the perspectives of socioeconomic status, natural environment conditions, and location factors using correlation analysis. The results indicate that: (1) Conflicts between ecological protection redlines and basic farmland protection zones, and conflicts between ecological protection redlines and urban growth boundaries are the main types of "three lines" conflict, accounting for 6.57% and 5.77% of the regional land areas, respectively in the Wuhan metropolitan area, and conflicts between farmland protection zones and urban growth boundaries are relatively few. (2) Spatial distributions of the three types of "three lines" conflict are different. Conflicts between ecological protection redlines and basic farmland protection zones are mainly distributed in the periphery of the Wuhan metropolitan area. Conflicts between ecological protection redlines and urban growth boundaries are mainly distributed in the core of the Wuhan metropolitan area. Conflicts between basic farmland protection zones and urban growth boundaries are mainly distributed in the transitional zone between the urban and rural ecotones. (3) The six indicators representing regional conditions have different effects on the intensity of the three types of conflicts. In conclusion, TLCI is a good measurement of regional comprehensive "three lines" conflict intensity. The spatial pattern analysis methods can well describe the characteristics of the "three lines" conflict. (3) The research on the formation mechanism and driving factors of "three lines" conflict needs to be further explored. This study can provide a systematic framework for analyzing "three lines" conflict and guidance to landscape planning for avoiding "multiple plans conflict."
