摘要:

【目的】 以郑州都市圈核心区为研究对象,在构建区域生态安全格局的基础上,借助土地利用转化矩阵对土地转化类型、程度进行分析,识别土地利用空间冲突分类,为核心区的土地利用规划管理提供依据,对生态空间的保护提供参考。【方法】 利用形态学空间格局分析(MSPA)方法识别目标源地,采用最小累积阻力模型(MCR)及重力模型提取潜在廊道并筛选出重要廊道,构建综合生态安全格局,将生态安全格局分为低、中、高3级,进而定量地判断和剖析土地利用空间冲突的类型和程度,识别出土地利用冲突的空间特征,分析其影响因素。【结果】 ①郑州都市圈核心区土地利用冲突分布特征显著,耕地生态冲突分布较为集中,以不冲突为主;建设用地生态冲突分布较为分散,不冲突区主要分布在各个市域范围的主城区中部,一般严重冲突、极严重冲突主要位于研究区的北部;在耕地建设生态综合冲突中,各冲突等级面积大小为不冲突>一般严重冲突>极严重冲突,其中耕地生态冲突占主导。②郑州都市圈核心区2000—2020年区域景观格局破碎化程度较高,分布不均衡,构成研究区生态空间的主要景观类型;耕地景观、草地景观的占比呈现部分的下降。【结论】 郑州都市圈核心区的土地利用用途转变程度、规模变化强度较大,耕地冲突、建设用地冲突和综合土地利用冲突较为明显。因此,该研究对于加强国土空间各类用地的管控及生态空间提质具有积极意义。

Abstract:

【Objective】The core area of the Zhengzhou Metropolitan area was investigated based on the construction of a regional ecological security pattern. The type and degree of land transformation were analyzed with the help of a land use transformation matrix, and the classification of land use spatial conflicts was identified, providing a basis for land use planning and management in the core area as well as a reference for the protection of ecological space. 【Method】The morphological spatial pattern analysis (MSPA) method was used to identify the target source area, the MCR model and gravity model were used to extract potential corridors and screen out important corridors, and the regional comprehensive ecological security pattern of “ecological source-ecological corridor-ecological network-hierarchical zoning” was constructed. The ecological security pattern was divided and analyzed. Next, the spatial characteristics of land use conflicts were identified, and the influencing factors were analyzed. 【Result】(1) The distribution of land use conflicts in the core area of the Zhengzhou Metropolitan area was significant, and the distribution of cultivated land ecological conflicts was relatively concentrated, mainly without conflicts. The distribution of ecological conflicts in construction land was relatively dispersed, the non-conflict areas were mainly concentrated in the middle of the main urban areas within each city scope, and the general serious conflicts and extremely serious conflicts were mainly located in the northern part of the research area. In the comprehensive ecological conflict of cultivated land construction, the size of each conflict level was no conflict, generally serious conflict, or extremely serious conflict, among which cultivated land ecological conflict dominated. (2) From 2000 to 2020, the regional landscape pattern in the core area of Zhengzhou Metropolitan area was highly fragmented and unevenly distributed, which constituted the main landscape type of ecological space in the study area. The proportion of cultivated land landscape and grassland landscape showed a partial decline. 【Conclusion】 The transformation degree and scale of land use in the core area of Zhengzhou Metropolitan area are relatively large, and the conflicts of cultivated land, construction land and comprehensive land use are relatively obvious. Therefore, the study has a positive significance for strengthening the control of various types of land use and improving the quality of ecological space.
