摘要
构建生态网络,加强破碎生境间的连接是生物多样性保护的重要措施之一。本研究以江西东江源区为研究区,利用最小累积阻力模型构建生态网络,并利用整体连通性指数、可能连通性指数以及形态学空间格局分析方法对生态网络的连通性和景观功能进行评价。结果表明:东江源区生态网络由15个生态源地、14条重要生态廊道和9个踏脚石组成;本研究所构建的生态网络能够提升东江源区生态源地间的连接度,提高绿色景观的完整性。研究结果可为东江源区生态网络的构建提供指导。
Constructing ecological networks to strengthen the connection between fragmented habitats is one of the effective approaches for biodiversity conservation.Taking the headwaters region of the Dongjiang River in Jiangxi as an example,we constructed ecological networks using minimal cumulative resistance model,and evaluated the connectivity of ecological networks and landscape functions using integral index of connectivity,probability index of connectivity,and morphological spatial pattern analysis methods.Results showed that the ecological networks of the headwaters region of the Dongjiang River consisted of 15 ecological sources,14 key ecological corridors,and nine stepping stones.The ecological networks constructed in this study would promote the connectivity between ecological sources in the headwaters region of the Dongjiang River and improve the integrity of green landscapes.Our results provide guidance for the construction of ecological networks in the headwaters region of the Dongjiang River.
