摘　　要：随着全球气候变暖、生物多样性减少、生境破碎化等环境问题日趋严重,"一带一路"沿线国家和地区在生态文明建设上面临着共同的挑战。如何在有限的资源条件下合理布局绿色基础设施以满足人类福祉的需求,仍是当前理论研究的热点和景观管理实践的主要难题。以新疆阿拉尔市为例,基于形态学空间格局分析、最小路径分析等方法识别对地区景观生态格局具有重要影响的源地与廊道,通过补充战略点的方式对网络进行优化,进而结合区域实际状况提出绿色基础设施网络的构建思路。研究结果可为阿拉尔市及阿克苏地区生态修复和绿地系统规划提供理论及实证依据,也为"一带一路"其他干旱区城镇绿色基础设施布局与生态安全格局构建提供可资借鉴的思路和方法。With the global warming,biodiversity decrease,habitat fragmentation and other increasingly serious environmental problems,countries and regions along the"Belt and Road"face common challenges in promoting ecological civilization.Under the condition of limited resource,how to build an distributed green infrastructure(GI)network reasonably to meet the demand of human well-being is still the focus of current researches and the main problem of landscape management practice.Taking Alar City in Xinjiang as an example,this study identifies the hubs and corridors that have an important impact on the landscape ecological pattern based on the morphological spatial pattern analysis and least-cost path analysis.After that,the network is further optimized through supplementing ecological strategic nodes,and then combining with the actual situation of the region,the idea of GI network construction will be put forward.The results can form the theoretical and empirical foundation for ecological restoration and green system planning in Alar City or Aksu Area,and also provide ideas and methods for GI network and ecological security pattern construction for other cities and towns of arid areas along the"Belt and Road".
