box-sizing: border-box;">生态网络的修复空间。生态安全格局理</span><span style="line-height: 1.45; box-sizing: border-box;">论是在景观生态学研究景观格局与水平</span><span style="line-height: 1.45; box-sizing: border-box;">生态关系流的基础上发展而来的，它通</span><span style="line-height: 1.45;

box-sizing: border-box;">具体来说，可主要考虑以下三点内容：</span></section><section style="text-indent: 2em; box-sizing: border-box;">(1)划定生态基质。生态基质在动植<span style="line-height: 1.45; box-sizing: border-box;">物种群维护、调节微气候和保护生态安</span><span style="line-height: 1.45; box-sizing: border-box;">全性能等方面的作用比中小型生态斑块</span><span style="line-height: 1.45; box-sizing: border-box;">更强。通过划定大型生态基质隔离区，</span><span style="line-height: 1.45; box-sizing: border-box;">限制该类地区的开发建设。</span></section><section style="text-indent: 2em; box-sizing: border-box;">(2)建设生态廊道。生态廊道是指在<span style="line-height: 1.45; box-sizing: border-box;">城市生态环境中呈线形或带状布局的，</span><span style="line-height: 1.45; box-sizing: border-box;">能够沟通和连接空间分布上较为孤立及</span><span style="line-height: 1.45; box-sizing: border-box;">分散的生态景观单元的景观生态系统空间</span><span style="line-height: 1.45; box-sizing: border-box;">类型。通过建设生态廊道，可以将相对孤</span><span style="line-height: 1.45; box-sizing: border-box;">立的点状生态斑块连接起来，构成完整</span><span style="line-height: 1.45; box-sizing: border-box;">连续的生态安全网络。这其中的关键是</span><span style="line-height: 1.45; box-sizing: border-box;">设定综合生态廊道，以强化城镇发展空</span><span style="line-height: 1.45; box-sizing: border-box;">间与生态基质的有机联系，拓展生态基</span><span style="line-height: 1.45; box-sizing: border-box;">质的服务功能，缓解城市对自然生态系</span><span style="line-height: 1.45; box-sizing: border-box;">统的压力，增加城市内部空间的景观异</span><span style="line-height: 1.45; box-sizing: border-box;">质性。</span></section><section style="text-indent: 2em; box-sizing: border-box;">(3)完善中小型斑块。斑块是区域生<span style="line-height: 1.45; box-sizing: border-box;">物物种生存繁衍的重要栖息地，具有重</span><span style="line-height: 1.45; box-sizing: border-box;">要的生态意义，是构成区域生态网络的</span><span style="line-height: 1.45;
