摘要
为进一步落实竹林风景线的建设,笔者以四川省首批13家竹林风景线建设单位管辖区内的竹林风景线为研究对象,基于文献搜集和实地调研,采用GIS技术对其进行构建要素的分类分级,获得了4个要素层、15个因子层,即生态基底层(生态系统服务功能重要性、生态敏感性、水系、坡度、高程)、产业开发层(第一产业、第二产业、第三产业)、文化设施层(重要接驳点、道路交通网络)以及景观格局层(破碎度、分离度、脆弱度、优势度、干扰度)。再利用熵值法计算出不同要素的权重,发现其重要性为生态基底层(0.390)>产业开发层(0.280)>文化设施层(0.210)>景观格局层(0.120),其中每个层次要素中的因子权重也不尽相同。研究表明已建的竹林风景线主要围绕“生态、产业、文化、景观”4个方面进行构建,生态占比最大,而生态和景观通常为关联要素,因此得出竹林风景线的构建模式主要分为三类,分别为“景观生态”类、“产业发展”类、“文化引领”类。该研究以“调研—分析—理解”为思路,给国内竹林风景线建设提供更科学、更系统的发展方向,同时也对完善竹林风景线研究体系起到促进作用。
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.
