On the one hand, with the increasing proportion of urban night economy in the overall urban economy, Chinese cities are becoming an almost all-weather city. There are some unique functions and characteristics in time and space. At the same time, new requirements for urban development and construction are put forward. For example, with the booming economy at night, what changes should be made to urban planning? How to carry out urban management?In the emphasis on sustainable development today, night as an indispensable metabolic link in the process of urban life, what impact on the overall development of the city? For this series of questions, we do not have a clear answer. Therefore, it is an urgent task to carry on the systematic research on the urban night economy to promote the rational and healthy development of the city.

On the other hand, with the rapid development of domestic tourism, the tourism industry of our country has changed from the stage of sightseeing tourism to the stage of holiday tourism, and the era of experience economy is coming, and tourism consumers are eager to get deeper satisfaction from leisure vacation. However, at present, the social and economic development of many small and medium-sized tourist cities in Guangxi lags behind, and the supporting facilities of tourism are not perfect, which cannot meet the market demand brought by the development and transformation of the tourism industry. Therefore, it is urgent to analyze, study and put forward feasible strategies in order to promote the development of small and medium-sized tourist cities in Guangxi.

Under this dual background, the author analyzes and studies the supporting facilities of night tourism in small and medium-sized tourist cities in Guangxi based on the professional perspective of urban planning. This paper introduces the strategy of urban economy at night,optimizes the supporting facilities of urban tourism, excavates the productivity of cities at night, and stimulates the economic vitality of small and medium-sized tourist cities at night.It can not only meet the market demand under the current tourism industry transformation,but also promote the sustainable economic development of local cities. It will be of great significance to many small and medium-sized tourist cities in Guangxi, which are rich in tourism resources but limited by location and economy.

This paper puts forward the introduction of landscape economic strategy into the planning process of landscape lighting in small and medium-sized tourism cities in the west, taking the construction of night scene lighting as an opportunity, from the market-oriented operation of landscape lighting facilities layout, “point-axis” development theory to focus on building, The industrial chain linkage development night tourism development three aspects, realizes the city environment quality optimization, the economic benign development win-win effect. And take Sanjiang Dong Autonomous County of Liuzhou City as an example to carry on the concrete the Sanjiang Dong Autonomous County of Liuzhou City as an example for specific analysis.

城市景观照明对城市建设与经济发展具有重要影响，大约三分之一都市旅游资源由夜景支撑，在改善投资环境和对外形象方面，夜景更是一笔无形资产[1]（图1）。我国城市夜景建设已有二十多年的历史，积累了一定的设计经验和理论体系。当前照明规划相关实践和研究多集中于：对城市节点进行具体的夜景营造[2-6]、照明与城市生态及光污染的防控[7-10]、夜景照明地域化的表达[11-14]，较少有从景观经济的角度进行系统研究。西部中小旅游城市多为山地城市，拥有丰富的山水资源和独特的城市格局，但经济相对落后，盲目照搬大型旅游城市的景观照明发展战略，结果往往差强人意。因此，从景观经济的角度探究夜景照明规划如何借助城市山水格局，创造独特的夜间城市形象，挖掘城市夜景建设“生产力”，激发城市活力，对于旅游资源丰富但受区位、经济等局限的众多西部中小旅游城市健康持续发展将具有重大意义。

1 景观经济策略提出背景

当前我国城市景观照明规划建设具有以下特征：论发展阶段，我国的城市景观照明正处于急速成长期[15]，起步较晚，但随着城市化进程的加快，全国各地景观照明建设热情不断升温，发展迅速令人惊讶；论规划目标，我国的城市景观照明以美化、营造城市夜间形象为主，打造成为城市特色景观、城市特色名片；论建设运营，多以政府单方为主，有限的财政多用于突击性的前期景观照明建设和后期的日常运营[15-16]；论系统性特点，我国城市景观照明规划较为滞后，实施性、规范性较差[15-16]，未能与城市旅游产业规划进行良好的协调，夜景照明产业呈现“单打独斗”的局面。由此导致我国城市景观照明规划手法存在一定弊端。
