This project is the design of the tourism service station in the coastal park, which not only meets the basic functional requirements of the park service station but also reconfigures the station space with the regional cultural characteristics of Qingdao. The design process is mainly conceived in five aspects: locality, landscape, identity, symbolization, and diversification. It integrates the cultural characteristics of Qingdao coastal tourism with the park landscape to create a tourist rest space with diversified experiences. The purpose of this paper is to explore the interface between the stations' design and the various links of the cultural tourism industry chain. The project will be created as the “Window of Qingdao” in Baisha River Park.

To determine the levels of gallic acid and ellagic acid by using high-performance liquid chromatography (HPLC) with R software hierarchical cluster analysisin Elaeagnus angustifolia L. gathered from different locations in Xinjiang.


A chromatographic column Diamonsil C18 with a size of 4.6 × 250 mm and 5 μm was used with methanol as A and 0.1% phosphoric acid aqueous solution as B as the mobile phase. The flow rate was 1 mL/min for the gradient elution and the injection volume was 5 μL. HPLC was performed with a detection wavelength of 260 nm and chromatographic column of 35 °C. In addition, R software hierarchical clustering method was used for studying the levels of gallic acid and ellagic acid in E. angustifolia L. from 10 areas.


Gallic acid and ellagic acid showed a good linear relationship between 7.375 and 236 μg/mL with a correlation coefficient of 0.9999, and between 3.625 and 116 μg/mL with a correlation coefficient of 0.9999 respectively. The average recovery values were 103.98 and 101.57%, and the Relative Standard Deviation (RSD) values were 1.92 and 1.47%.


Differences in the levels of gallic acid and ellagic acid in E. angustifolia L. leaves from different areas in Xinjiang showed that both were the highest in Kuitun.
