Abstract:
In order to further implement the construction of bamboo landscape, this paper investigated the first 13 bamboo landscape construction projects in Sichuan Province. Based on literature review and field study, GIS technology was applied to classify and grade its construction elements, and 4 element layers and 15 factor layers were obtained. They were ecological base layer (importance of ecosystem service function, ecological sensitivity, drainage, slope and elevation), industrial development layer (primary industry, secondary industry and tertiary industry), cultural facilities layer (important interchange station and road traffic network), and landscape pattern layer (fragmentation, isolation, fragility, dominance and interference). Entropy method was used to calculate the weights of different elements, and it was found that the importance rankings were as follows, ecological base layer (0.390) > industrial development layer (0.280) > cultural facilities layer (0.210) > landscape pattern layer (0.120). Moreover, the weights of factors in different elements were different. Results indicated that the existing bamboo landscape was mainly built on four concepts, that is, "ecology, industry, culture and landscape", of which ecology accounted for largest proportion, while ecology and landscape were usually associated elements. Therefore, it is concluded that there are three categories of construction modes of bamboo landscape, namely, "landscape ecology", "industrial development" and "cultural guidance". Based on the idea of "investigation, analysis and understanding", this study provides a more rigorous and systematic direction for the construction of bamboo landscape in China, and also facilitates the improvement of research system on bamboo landscape.
