城市标志性形象是城市精神和文化内涵的外在体现，具有多方面的功能与价值。兰州自然环境独特，历史文化积淀深厚，但标志性形象空间分布不均衡，地域特色不鲜明，营销保护不积极。今后应以地域文化为根基，围绕黄河文化构建城市主题标志性形象，按照功能特征打造节点区域标志性形象，依托环境本底塑造人与自然和谐的整体景观形象，以提升城市品味，增强城市竞争能力，有效推动城市社会经济的健康持续发展。

Natural environment is unique in Lanzhou, and there is deep accumulation of the history and culture there. However, its symbolic image is lopsided in the spatial arrangement, and its region characteristic and marketing protection are limited.

Implementation of these measures could lift its taste, enhance its competitive ability, and effectively promote socioeconomic sustainable development of the city.
