border-box;">在新时代城市国土空间规划和城镇化绿色转型的双重语境下，生态保护红线划定及管控成为城乡生态空间保护的</span><span style="box-sizing: border-box;">重要手段，然而由于生态保护红线规划的技术方法及管控手段不足，部分城市生态保护红线范围内的城乡生态空间普遍存在</span><span style="box-sizing: border-box;">着系统连接性欠缺、格局破碎等问题，导致其生态效应削弱甚至骤减。因此，有必要探讨建构生态保护红线效应评价的技术</span><span style="box-sizing: border-box;">方法，用以评估生态保护红线的规划方案及实施效果。文章以生态网络连接度的相关理论为研究前提，通过分析生态网络连</span><span style="box-sizing: border-box;">接度与生态保护红线效应之间的内在关联，构建生态保护红线效应的评价方法体系，并以此对湖北武穴市生态保护红线效应</span><span style="box-sizing:

0px;box-sizing: border-box;">对生态网络连接度的评价研究主要集中在两个方<span style="box-sizing: border-box;">面：①对特定生物种的相关研究。以特定生物种的迁</span><span style="box-sizing: border-box;">移扩散、觅食活动和繁殖过程为依据，</span><span style="box-sizing: border-box;">对生物栖息地、生境的生态连接和相互</span><span style="box-sizing: border-box;">作用程度进行评价，从生态网络或景观</span><span style="box-sizing: border-box;">格局的角度进行局部结构调整来保护生</span><span style="box-sizing: border-box;">物多样性，如姜广顺等人对马鹿生境网</span><span style="box-sizing: border-box;">络、杨天翔对鸟类边缘种的位移痕迹进</span><span style="box-sizing: border-box;">行了分析评价，并探讨了人类的活动对</span><span style="box-sizing: border-box;">斑块和网络的影响。②对距离阈值的</span><span style="box-sizing: border-box;">相关研究。以环境适应性和生物种的迁</span><span style="box-sizing: border-box;">移扩散为前提，通过选取不同的距离阈</span><span style="box-sizing: border-box;">值，计算和评价不同阈值下生态网络连</span><span style="box-sizing: border-box;">接度与相应景观结构的变化，对比分析</span><span style="box-sizing: border-box;">不同斑块在不同连接度下的重要程度和</span><span style="box-sizing: border-box;">生态服务功能。例如，刘常富等人通过</span><span style="box-sizing: border-box;">对斑块的种类、连通性指数、组分数和</span><span style="box-sizing: border-box;">整体链接数进行评价，筛选出适合沈阳</span><span style="box-sizing: border-box;">市的网络连接度阈值；陈杰等人分析</span><span style="box-sizing: border-box;">了不同阈值下斑块的重要指数、组分数</span><span style="box-sizing: border-box;">和连通性指数的变化，以及其对生态网</span><span style="box-sizing: border-box;">络连接度和整体格局的影响。</span></p><p style="text-indent: 2em;white-space: normal;margin: 0px;padding: 0px;box-sizing: border-box;">对生态效应的评价研究主要集中在<span style="box-sizing: border-box;">两个维度：①对典型生态系统服务价值</span><span style="box-sizing: border-box;">和效应的量化。例如，杜瑶等人对森林</span><span style="box-sizing: border-box;">生态系统服务功能、草地生态系统服务</span><span style="box-sizing: border-box;">功能、湿地生态系统服务功能及农田生态</span><span style="box-sizing: border-box;">系统服务功能进行了量化评价。②对</span><span style="box-sizing: border-box;">城市生态系统效应和服务价值的综合研</span><span style="box-sizing: border-box;">究评价。例如，宗跃光等人针对城市景观</span><span style="box-sizing: border-box;">生态价值的边缘效应及城市生态系统服务</span><span style="box-sizing: border-box;">功能的价值结构进行了计量性分析；</span><span style="box-sizing: border-box;">徐剑波等人基于遥感技术的支持，以广</span><span style="box-sizing: border-box;">州市为例更加准确地评价了绿地生态效</span><span style="box-sizing: border-box;">应的空间差异性及其动态变化；吴敏</span><span style="box-sizing: border-box;">通过建立网络连接度、网络渗透度和网</span><span style="box-sizing: border-box;">络密度的“评价三指标”，将生态网络</span><span style="box-sizing: border-box;">与景观格局紧密联系，阐述了城市绿地</span><span style="box-sizing: border-box;">生态网络的效应体系和空间增效途径。</span></p><p style="text-indent: 2em;white-space: normal;margin: 0px;padding: 0px;box-sizing: border-box;">由此可见，一方面，生态网络连接<span style="box-sizing: border-box;">度评价的相关研究侧重于探讨特定生物</span><span style="box-sizing: border-box;">体的迁移扩散及生境破碎化，而对于系</span><span style="box-sizing: border-box;">统地从格局和网络的角度探讨不同生态</span><span style="box-sizing: border-box;">核心要素之间生态连接度的研究较为薄</span><span style="box-sizing: border-box;">弱。另一方面，生态效应的理论与评价</span><span style="box-sizing: border-box;">方法仍未形成统一体系，生态资源及其</span><span style="box-sizing: border-box;">效应的定量分析方法较为单一化，缺乏</span><span style="box-sizing: border-box;">城乡规划的宏观视角，很少从全域全要</span><span style="box-sizing: border-box;">素的角度探讨结构性网络的生态效应，</span><span style="box-sizing: border-box;">难以抓住保护重点，同时在具体评估过</span><span style="box-sizing: border-box;">程中缺乏价值目标与空间手段间的有机</span><span style="box-sizing: border-box;">衔接。</span></p></section><section style="padding: 0px
