[目的] 揭示目前广东省东莞市水鸟生态廊道的空间分布格局
为该区域生态修复提供科学依据。[方法] 以东莞市的关键物种水鸟为出发点
基于东莞市水域数据与阻力面构成数据
运用最小积累阻力模型算法、中性度原理、电流理论等方法开展研究。[结果] 在东莞市域范围内构建生态廊道共26条
总长度为259.91 km。其中重要、较为重要、一般重要的生态廊道各6条、15 条和5条。重要生态廊道与一般生态廊道以集中分布的情况出现
而较重要生态廊道呈现散布状态。所获取的关键障碍点空间位置特征多为人为干扰程度严重的区域。[结论] 在生态廊道空间布局方面,主要应以优化城市本底条件为基础,维持整个城市生态空间平衡;在廊道连通性提升角度,应以充分发挥廊道自生的生态功能为导向,保证整体廊道网络空间的连续性;在障碍点修复角度,应降低人类活动的强度干扰,减轻水鸟途经该廊道的阻碍。
[Obiective] The spatial distribution pattern of waterfowl ecological corridors in Dongguan City
Guangdong Province were studied in order to provide a realistic basis for its ecological restoration.[Methods] We considered waterfowl as the key species of Dongguan City. The research was carried out by using the minimal cumulative resistance (MCR) model
the centrality principle of habitat and connection
and the circuit theory based on water data and resistance surface composition data of Dongguan City. [Results] A total of 26 ecological corridors with a total length of 259.91 km were constructed in Dongguan City
of which six
fifteen
and five were important
more important and generally important ecological corridors respectively
and the important and general ecological corridors were centrally distributed
while the more important ecological corridors were dispersed. The spatial locations of the key obstacles were characterized as areas with serious anthropogenic disturbances. [Conclusion] In the perspective of spatial layout of ecological corridors
the main purpose is to optimize the urban background conditions and maintain the balance of the entire urban ecological space. In the perspective of corridor connectivity enhancement
it is suggested to give full play to the self-generated ecological function of the corridor as a guide to ensure the continuity of the overall corridor network space. In terms of restoration of obstacles
the intensity of human activities should be reduced to alleviate the obstruction of waterbirds passing through the corridor.
