双目标模式下芜湖市中心城区公园数量和规模的优化

Optimization of the Number and Scale of Urban Parks in Downtown Wuhu under the Dual-Target Mode

随着城镇化水平不断提高,人们对作为城市主要自然景观和休闲游憩场所的城市公园需求也在日益增加,城市公园数量和规模的合理性越来越受关注.本文在兼顾居民到公园距离最短的基础上,考虑到公园数量和规模增大可能对城市交通造成干扰,提出权衡可达性和公园对交通流干扰性的双目标模式,来探索芜湖市公园的最佳数量和规模,实验共产生1377次结果,挑选出比现状值更佳的113种组合进行比较,得到4组最佳的公园数量和规模,为芜湖市公园规划和发展的研究提供了一种新的思路,有利于促进芜湖市有限土地资源的合理利用.

As the level of urbanization continues to increase,people are increasingly demanding urban parks,which are the city's main natural landscape and leisure and recreation sites.The rationality of the number and scale of urban parks is getting more and more attention.This paper takes into account the shortest distance between residents and parks,and considers that the increase in the number and size of parks may cause disruption to urban traffic,and proposes a dual-objective model of trade-off accessibility and parks' disruption to traffic flow to explore the parks in Wuhu city.The best number and scale of experiments resulted in a total of 1377 results.A total of 113 combinations that were better than the current status were selected for comparison.The number and scale of the best four parks were obtained,providing a study for the planning and development of parks in Wuhu city.The new ideas are conducive to the rational use of limited land resources in Wuhu city.
