干旱地区节水型公路植物景观设计规划研究-以克拉玛依市为例

干旱地区的公路由于自身环境恶劣,为使公路植物景观产生更大生态效益和社会效益,早日实现公路植物景观设计中的功能化、生态化与可持续化,已经成为当前干旱地区公路建设中急需解决的一个现实问题。目前在干旱地区的公路上进行植物景观设计时植物的成活率不高,难以得到理想的景观效果。基于种植植物存活率提出干旱地区节水型公路植物景观设计规划方案。以新疆维吾尔族自治区克拉玛依市作为实验地点,以植物种类、种植深度、种植间距及回填深度作为研究指标,探讨该地区公路节水型植物景观的最佳设计方案。实验结果表明:耐旱型乔木类植物、种植间距为5m、种植深度80cm、回填深度30cm为最佳种植条件,为克拉玛依干旱地区公路的节水型植物景观设计提供了可靠依据。最后提出了该地区节水型公路植物景观设计规划方案,具有较高的实际应用价值。

Study on plant landscape design of water saving highway in arid area- Taking Karamay city as an example

Arid area highway due to its poor environment, produce greater ecological benefits and social benefits for the highway landscape, the early realization of ecological function, highway landscape design and sustainable development, has become a realistic problem needs to be solved urgently in highway construction in arid area. The plant survival rate is not high, it is difficult to obtain the ideal landscape effect when the plant landscape design is carried out on the highway in the arid area. Plant landscape design and planning of water saving highway in arid area based on the plant survival rate. Taking Karamay city of Xinjiang Province as the experimental site, the optimum design scheme of water saving plant landscape in the area was discussed with the plant species, planting depth, planting spacing and depth of backfill as the research targets. The experimental results show that the drought tolerant tree plants, planting spacing is 5m, the planting depth of 80 cm, the depth of backfill 30cm is the best planting conditions, provide a reliable basis for water-saving plant landscape design of highway in arid areas of Karamay. At last, it puts forward the plan of plant landscape design of water saving highway in the area, which has high practical application value.
