摘要:
从人居环境角度对城市生态空间的研究有利于从“以人为本”出发提升生态系统服务,改善人居环境质量。运用GIS的空间分析功能和基于AHP的多因子综合评价法从生态服务价值、空间使用功能、城市特色空间塑造三个方面对株洲市中心城区的生态空间进行了评价分析。结果表明:(1)研究区生态空间的生态服务总价值为21697.73万元,单位面积提供的生态服务功能价值平均为5.29万元;生态服务功能中空气净化服务价值最低,占总服务价值的0.39%,是空间生态服务功能提升的重点。(2)研究区空间使用功能水平为良好,空间服务综合得分为64.94;存在的主要问题是生态空间类型单一、游憩空间所占面积较少、生态空间的安全性和可持续性需加强。(3)城市空间具有地方特色,“山-水-城”整体联系性良好;主要问题是特色城市空间分布不均,历史文化景观要素使用较少。

Abstract:
A study of urban ecological space from the perspective of human settlements is beneficial to improve ecosystem services and the quality of human settlements ,which starting from “people foremost”. The Spatial analysis function of GIS and Multi factor comprehensive evaluation method based on AHP were applied to evaluation and analysis the ecological space in the downtown area of Zhuzhou from three aspects: ecological service value, space use function and urban characteristic space. The research results indicated that:(1)The total value of ecological services in ecological space of the study area was 21697.73million yuan, the average value of the ecological services provided by the unit area was 52900 yuan;The lowest value of ecosystem services was air purification services, which accounted for 0.39%,was the key point of the improvement of space ecological service function.(2)The level of space use function in the study area was good,the composite score for space services was 64.94;The main problem were ecological space type was single,the area of recreational space is relatively small,the safety and sustainability of ecological space need to be strengthened.(3)The ecological space of the study area had local characteristics,”Mountain -water-city” had good integrity and connection;The main problem were uneven spatial distribution of the local characteristic space,the use of historical and cultural landscape elements was few.
