摘　　要：针对干旱区恶劣的自然环境条件,建立一套基于"目标-准则-指标"3个层次的绿地适宜性评价体系。以新疆北屯市为例,采用层次分析法评价研究区绿地适宜性,并在此基础上提出绿地生态设施功能分区与规划对策,为干旱区城市绿地规划和建设提供依据和参考。结果表明,林地(42.39%)和农田(30.32%)是研究区主要景观,有较好的生态基底;绿地极适宜区(23.6%)是绿地丰富、人类休憩和旅游较频繁的区域,高适宜区(32.1%)分布在极适宜区周围的地带,中适宜区(21.6%)现有植被生态功能较低、受间接人为活动影响较强、生态系统结构较差,低适宜区(14.5%)植被稀疏、生态环境差,不适宜区(8.2%)主要是人类活动的硬质表面;结合北屯市土地利用现状和城市发展需求,软质表面被划分为绿地生态恢复区、绿地生态保育区、中低影响发展区和绿地适宜发展区,对各区制订对策为北屯绿地建设提供理论指导和科学依据。Focused on the conditions of severe natural environment in arid area,a suitability evaluation system for green space based on“Target,Criterion,Index”was established.Beitun City of Xinjiang was set as the study area,the green space suitability was evaluated by AHP,and the functional partition and planning countermeasures of greening ecological facilities were put forward.This suitability evaluation system could provide the basis and reference for the planning and construction of urban green space in arid area.The results showed that the forest land(42.39%)and farmland(30.32%)were the main landscapes of Beitun City,which provided a better ecological base for the construction of green spaces.The green area was large in the most suitable area(23.6%),which distributed around by the highly suitable area(32.6%).Moreover,the moderately suitable area(21.6%)had lower ecological function and was influenced by human activities indirectly.The low suitable area(14.5%)had sparse vegetation and poor ecological environment.The non-suitability area(8.2%)was mainly the hard surface of human activities.Combined the status of the land use in Beitun City with urban development needs,the existing soft surface were divided into ecological restoration area,green land ecological conservation area,middle and low impact development area and green space suitable development area,and the countermeasures of this areas were proposed based on the theoretical guidance and scientific basis for the green space construction of Beitun City.
