城市建设使得场地中的土壤条件与自然环境相比有很大的差异,进而直接或间接影响城市生态环境质量.通过科学适宜的人工干预,城市场地土壤改良在场地可持续性设计方法中越来越重要.针对建成环境中的场地土壤类型,提出生态服务功能需求下的土壤改良设计方法,是城市建成环境场地设计中适宜性生态系统营建的重要途径.从土壤因子与植物景观营造的关系出发,指出基于土壤因子进行植物景观营造的必要性,并从植物与土壤的维护和跟踪监测两个方面,研究了场地可持续管理的方法; 以西建大南门花园为例,基于土壤适宜性改良对草本植物群落进行设计与实验性研究,验证了不同的土壤改良设计方法对土壤的改善和对植物生长的促进效果.
Urban construction makes the soil conditions in the site very different from the natural environment, It affects the quality of the urban ecological environment directly or indirectly. Through scientific assessment and appropriate manual intervention, urban site soil improvement is becoming more and more important in site sustainability design methods. The assessment of the suitability of soil types in the built environment, and the proposed soil improvement design method under the demand of ecological service functions are important ways to construct suitable ecosystems in the design of urban built environment sites. Based on the relationship between soil factors and plant landscape construction, the necessity of plant landscape construction based on soil factors is pointed out. From the aspects of plant and soil maintenance and follow-up monitoring, the methods of sustainable management of the site were studied. Taking the Southgate garden as an example, experimental observations for herbaceous community were carried out on the basis of soil suitability evaluation and improvement, and different soil improvement design methods help improve soil and promote plant growth.
