公路建设对旱区景观格局的影响及公路设计对策研究——以宁夏滨河大道为例

Effect of Highway Construction on Landscape Pattern in Drought Region and Highway Design Countermeasure: A Case Study on Ningxia Yellow River Riverside Avenue

就中国西部旱区生态景观敏感的特殊性,以宁夏黄河金岸滨河大道(银川段)114km的工程为例,应用Google Earth、GETScreen和Auto CAD等相关软件对公路沿线景观格局进行数据采样。在此基础上,对其景观格局用地指标、景观破碎度和景观形状指数等相关指标进行分析,确定公路建设对旱区景观格局的影响方式,并指出公路方案设计是决定公路建筑物影响景观格局的关键阶段,提出旱区公路设计应遵循的基本原则。

Based on the specific sensitive of ecological landscape in droughty area of Western China, this paper sampled the data of Ningxia Yellow River Riverside Avenue by using Google Earth, GETScreen, Auto CAD and other related software for data sampling on the highway landscape pattern, determined the mode of highway construction impact on the arid landscape pattern by analyzing the land use index of landscape pattern, landscape fragmentation, landscape shape index and other related indexes, pointed that the highway design is the key stage to decide the impact on landscape pattern by highway building and put forward the basic principles which should be followed in highway design.
