摘要:

在高度城市化背景下,开展生态廊道重要性评价研究,对维护城市生态安全格局具有重要意义。选取高度城市化但同时物种多样性较高的深圳作为研究区,构建基于主导功能分类的生态廊道重要性评价方法,为生态廊道精细化管理和布局优化提供科学依据。结果表明:① 通过最小累积阻力面模型识别的源间连接廊道大部分与已规划廊道重合,但仍有少部分未被覆盖,应将其规划为生态廊道并严格管控。② 各相邻城市组团间均有大型生态斑块或组团隔离廊道予以隔离,应控制组团隔离廊道内部建设用地规模。③ 根据重要性评价,8条生态廊道被纳入一级生态廊道,12条被纳入二级生态廊道,一级生态廊道基本兼具生物和景观连通、组团隔离两种功能,具有不可替代性且自身情况较好,对生物多样性维护及阻止建设用地无序蔓延有着十分重要的作用,应纳入基本生态控制线一级管制区进行严格管控。

Abstract:

Ecological corridor plays an important role in biodiversity protection and disordered extension of city area prevention, as it is a bridge to link ecological patches, also an important division of urban group segregation. Therefore, it is helpful to evaluate the significance of ecological corridor in highly urbanized areas for ecological security pattern protection. In this paper, Shenzhen is taken as a case to explore significance evaluation method of ecological corridor, for it is a highly urbanized region with high species diversity. The significance evaluation method of ecological corridor has been constructed and applied, in order to provide scientific basis for fine management and layout optimization of ecological corridor, and also enrich the research on significance evaluation of ecological corridor. Some conclusions can be drawn from the evaluation results as follows: (1) Most of the corridors between the ecological source region identified by the minimum cumulative resistance surface model have been almost overlapped with planned corridors, and the others should be planned for the ecological corridors with strict control. (2) Each urban group has been separated by a large ecological plaque or planned group segregate corridor, and construction land scale should be controlled in group segregate corridors. (3) Eight ecological corridors have been divided into the first level ecological corridor based on the evaluation results, as they have two functions, which are irreplaceable, and keep a good condition. The first level ecological corridors should be managed strictly for their important role in biodiversity protection and disordered extension of construction land prevention.
