摘要
高密度城市更新背景下,人工型城市困难立地(Artificial Challenging Urban Sites,ACUS)在公园绿地建设中的作用日益彰显。文章基于2008-2019年上海市中心城(外环线以内)公园绿地(G类)遥感解译数据,对其中由人工型城市困难立地改建的公园绿地的规模及空间分布特征进行了研究。由人工型城市困难立地改建的公园绿地,在上海市中心城公园绿地建设中的典型增益作用,至少表现在3个方面:一是对中心城公园绿地的用地资源增补效益;二是对中心城公园绿地的空间位置前移效益;三是对中心城公园绿地的景观格局提升效益。ACUS绿地对高密度城市生态系统服务提升的意义十分重大。
Under the background of high-density urban renewal,Artificial Challenging Urban Sites(ACUS)plays an increasingly important role in park green space construction.Based on the remote sensing interpretation data of park green space(land use type G)in the central city of Shanghai(within the outer ring road)from 2008 to 2019,this paper studies the scale and spatial distribution characteristics of park green space reconstructed from Challenging Urban Sites.The park green space reconstructed from Artificial Challenging Urban Sites(hereinafter referred to as ACUS green land)plays a typical role in the construction of park green space in the central city of Shanghai in at least three aspects:first,the benefit of land resources supplement for the park green space in the central city;second,the benefit of moving forward the spatial position of the park green space in the central city;third,improving the landscape pattern of the park green space in the central city.Thus,ACUS green land plays an important role in improving ecosystem services in high-density cities.
