Context

As an important type of sustainable landscape patterns, ecological security patterns focus on the spatial assessment of landscape function importance. However, there is a lack of attention to the scale effect, one of core cognitions of landscape ecology, especially the impact of extent changes on sustainable landscape patterns.

Objectives

Taking Weifang City and its surrounding six cities as the study area, this study was aimed to integrate regional and interregional approaches to identify ecological security patterns with a special focus on the effect of spatial extent changes.

Methods

We assessed the ecosystem service importance and integrated the ecological sources identified in view of regional and interregional perspectives. The key or fragile ecological corridors were then identified and the differences of ecological security patterns in different approaches were explored through several landscape metrics.

Results

11 central ecological sources and 21 surrounding ecological sources were identified. 70% key ecological corridors were the interregional ecological corridors across Weifang City and other cities. Different study extents would cause up to about 24% of the difference in high ecosystem service importance areas of Weifang City, and the corridor connectivity could be improved in the ecological security patterns by integrating the regional and interregional approaches.

Conclusions

This study made up for the shortcomings of identifying sustainable landscape patterns within the single spatial extent, especially the discontinuity of ecological sources between the adjacent areas through regional approach, and the neglected local ecological land conservation through interregional approach.

整合区域和区域间方法以识别生态安全模式

语境

作为可持续景观格局的一种重要类型，生态安全格局侧重于景观功能重要性的空间评估。然而，人们缺乏对尺度效应的关注，尺度效应是景观生态学的核心认知之一，尤其是程度变化对可持续景观格局的影响。

目标

本研究以潍坊市及其周边六个城市为研究区域，旨在整合区域和区域间的方法来识别生态安全模式，并特别关注空间范围变化的影响。

方法

我们评估了生态系统服务的重要性，并整合了根据区域和区域间观点确定的生态资源。然后确定关键或脆弱的生态走廊，并通过几种景观指标探讨不同方法中生态安全模式的差异。

结果

确定了11个中央生态源和21个周围生态源。70％的主要生态走廊是潍坊市和其他城市之间的区域间生态走廊。不同的研究程度将导致潍坊市高生态系统服务重要区的差异约占24％，并且通过整合区域和区域间方法可以改善生态安全模式中的走廊连通性。

结论

这项研究弥补了在单一空间范围内确定可持续景观格局的缺点，特别是通过区域方法确定相邻区域之间生态资源的不连续性，以及通过区域间方法确定被忽视的局部生态土地的缺陷。
