现代园林植物群落时空扩散模拟方法研究

Study on Spatio-Temporal Diffusion Simulation Method of Modern Garden Plant Communities

以城市园林的文化特色基础为目的建设现代化城市园林绿化规划,并对城市园林植物群落时空扩散进行建模处理,以期建设出更具新颖性的园林,在弘扬优秀文化的同时也可吸引更多游客的到来。传统园林规划没有使游客了解当地的历史文化,造成游客再次游玩的兴趣下降,同时缺少文化设计的园林建设也让游客缺乏记忆点。因此,以园林植物群落的时空扩散模拟方法设计现代园林具有至关重要的意义。该方法根据城市分区,提取城市自然环境特征与历史文化特征;通过设计可以展现历史文化特色的园林城市植物群落空间建设方案,改变原有的空间结构;以CA模型为基础,结合摩尔规则和网格,构建现代园林植物群落时空扩散模拟模型,根据模型建设园林的特色植物和当地稀有植物,实现文化浓厚的园林城市建设。结果可知,此次提出的植物群落时空扩散模拟方法,建设园林的特色植物和当地稀有植物,详细了解该城市园林特色、讲解历史信息、增添游览趣味,为城市的旅游行业发展,提供可靠的技术支持,并且对比分析后,该方法的评估分A1和A2组的分数在9.1分以上,A3和A4组的评分在6.2分以上,该值均高于传统方法,具备了更高的应用价值,由此可见,该建设方法能增添现代园林的特色,更适合当下现代园林的建设需求。

This paper aims to build a modern urban landscaping plan based on the cultural characteristics of urban gardens, and models the spatio-temporal diffusion of urban garden plant communities, with a view to building a more innovative garden and attracting more tourists while spreading excellent culture. The traditional garden planning did not make tourists understand the local history and culture, resulting in a decline in tourists’ interest in visiting again. At the same time, the garden construction with weak culture also made tourists ignore the city. Therefore, it is of great significance to design modern gardens by simulating the spatiotemporal diffusion of garden plant communities. This method extracts the characteristics of urban natural environment and historical culture according to urban zoning;By designing the space construction scheme of plant communities in garden cities that can show historical and cultural characteristics, the original space structure can be changed;Based on CA model, combined with Moore’s rule and grid, a simulation model of temporal and spatial diffusion of modern garden plant community is constructed. According to the model, garden characteristic plants and local rare plants are constructed to realize the construction of a garden city with rich culture. It can be seen from the results that the proposed simulation method of spatio-temporal diffusion of plant communities, the construction of characteristic plants and local rare plants in the garden, the detailed understanding of the city’s garden characteristics, the explanation of historical information, and the increase of tourism interests can provide reliable technical support for the development of the city’s tourism industry. After comparative analysis, the evaluation score of this method is above 9.1 in A1 and A2 groups, and above 6.2 in A3 and A4 groups. This value is higher than that of traditional methods with higher application value. It can be seen that the construction methods proposed this time can increase the characteristics of modern gardens and meet the construction needs of modern gardens.
