| 中文摘要: |
| 基于电路理论连通性模型对生态安全格局构建研究与应用发展进行探究。电路理论是一种
较新的生态廊道构建模型,生态安全格局的主要内容包括生态系统的保护和改善以及人类社会必要需求的合理发展与生态系统承受供给之间的均衡调节。对其研究发展历程及应用潜力以及电路理论连通性模型的优势性与局限性进行分析,对生态格局构建的多种研究方法进行对比分析。结果表明,物种对所穿越的景观不一定会选择最优路径,而是有多条路径可以选择。基于电路理论的连接度模型以电阻距离代替最小累积成本距离,电阻距离随物种到达栖息地或景观资源斑块的连接路径的增加而减小,通过电流密度的计算可有效识别对景观连通性有重要影响的景观要素和“夹点”地区,且“夹点”的位置不受廊道宽度的影响。 |
| 英文摘要: |
| This study explored the research and application development of ecological security pattern
construction based on the circuit theory connectivity model. Circuit theory is a relatively new model for
constructing ecological corridors. The main components of ecological security patterns include the protection
and improvement of ecosystems, as well as the balanced regulation between the rational development
of necessary human societal demands and the supply capacity of ecosystems. The research development, application potential, advantages, and limitations of the circuit theory connectivity model were analyzed,
and various research methods for ecological pattern construction were compared. The results indicated
that species did not necessarily choose the optimal path when traversing a landscape but might select from
multiple available paths. The connectivity model based on circuit theory used resistance distance instead
of the least cumulative cost distance. The resistance distance decreased as the number of connecting paths
for species to reach habitats or landscape resource patches increases. By calculating current density, key
landscape elements and “pinch points” that significantly influenced landscape connectivity could be effectively
identified, and the location of these “pinch points” was not affected by corridor width. |
