环城游憩带(ReBAM)发展到高级阶段将出现空间聚散形态。城市居民游憩需求的规模扩张和结构变动要求ReBAM在供给面形成响应。在不少城市,ReBAM已具备一定的整体开发水平,但内部节点(旅游地)发展不均。在此情况下,优化需求-供给的结构性匹配成为ReBAM发展的内在趋势。环城游憩汀(ReLAM)是指依据游憩需求导向,向特定时空内其他游憩节点引送游憩流的现实或潜在功能较强的优势节点。ReLAM以改善ReBAM节点关联为导引,扩展游憩时空行为,促进节点整合互惠,提升居民游憩品质和ReBAM利用水平。ReLAM形成的根本原因是游憩需求增强和时空条件滞后之间的矛盾,分为主观因素驱动、客观因素驱动和混合驱动3种基本类型。游憩需求状态、垂引节点吸引力、时空结构对ReLAM的形成及其功能具有关键影响,游憩市场规模发挥调节作用。ReLAM是兼具集聚和辐射功能的新型空间要素,对非均衡发展的游憩区域具有优先指导价值。
ReBAMs will come to the disequilibrium patterns of both functional and geographical constitutions through the course of evolution. In this regard, ReBAM spots need to have higher efficiency in answer to the promoted demands and upgraded competitions of recreational markets. To seek better performances the ReBAM spots should ini-tiate with each other to be smarter entities by means of cooperation. From the geographical view, cooperation between ReBAM spots is signified by reorganizing the network of recreation flows. Principles of recreationist behaviors make these flows spillovers generally from higher-class to lower-class spots. Such asymmetric flows package the participating spots as a unity to gain additive advantages to their competitors. Meanwhile,the “ asymmetry” of flows confers orders upon each single spot. In this research, the higher-class ReBAM spot as the “ spillover origination” of recreation flows is focused on and temied Recreational Leap-frog around Metropolis ( ReLAM). For ReBAM trips, ReLAMs are the most preferred, even the only spots planed by recreationists. Given the more flexible temporal-spatial budgets, it can be acknowledged that ReLAMs have the potential of directing recreationists to other feasible spots. To make this potential a reality, conditions and mechanism of ReLAM are analyzed. As summary, ReLAM can be a way to promote the total utility of recreation trips as well as ReBAM development.
