摘要 目前设计领域都在向着数字化迈进,其中在建筑与城市规划领域以BIM(Building Information Modeling)和CIM(City Information Modeling)的研究最为成熟,但在小区域精准落地的风景园林设计中,数字化的应用仍处于起步阶段,尤其在场地规模较小且原始地形可塑潜质较差的沟道地形的辅助设计中,数字化研究和应用仍处于空白。以可塑性较差的西宁市某沟道公园的原始地形为对象,利用Rhino+Grasshopper编程插件分析地形,通过开源端口Python代码与遗传算法辅助地形低影响优化设计,实现土方量最小,为不同设计方案经济比选提供支撑。最终完成场地地形模型的构建,并具备低影响开发必要条件,且设计与施工之间拟合度较高,从而确保了设计开发工作的可行性。 At present,the design field is developing digitalization.Building Information Modeling(BIM)and(City Information Modeling)CIM research is the most mature in the field of architecture and urban planning.But in the landscape design of small area accurate landing,the application of digitalization is still in initial stage.In the auxiliary design of channel terrain with small site scale and poor plasticity potential of the original terrain,digital research and application remain blank.This paper takes the original terrain of a gully park with poor plasticity in Xining City as the object.The terrain is analyzed by the Rhino+Grasshopper programming plug-in.The low-impact optimization design of terrain is obtained by open-source port Python code and genetic algorithm to achieve the smallest amount of earthwork,which provides support for the economic comparison of different design schemes.Finally,the construction of the site terrain model is completed with the necessary conditions for low-impact development.The design and construction fits high to ensure the feasibility of design development work.
