摘要
全球气候系统变暖趋势进一步持续,近海海平面上升加剧了滨海地区土壤盐渍化的程度,对滨海园林健康及生态安全提出了严峻挑战。通过测定上海21种常见园林树种10项因子5个不同盐分胁迫浓度下的指标变化,对其耐盐机理及耐盐性强弱进行探讨。结果表明:指标因子的选择对树种抗盐性综合评价起主导作用;不同树种应对盐分胁迫的生理策略不同;树种耐盐幅度的测定能够指导"适地适树"规划原则的实现。该结论可为上海滨海地区耐盐性园林树种的选择提供技术对策。
Soil salinization in Shanghai coastal areas has increased with sea level rise in response to climate warming,which poses a severe challenge to coastal landscaping.Salt tolerance mechanism and salinity tolerance of 21 popular landscape tree species were measured experimentally with 10 factors in 5 comparison tests in Shanghai.The results showed that the selection of factors was significant for the evaluation of the salt tolerance of tree species;the different physiological strategies for different tree species to cope with salt stress;and the salt tolerance magnitude of trees could guide the realization of planning principles of"ring place,right trees".The conclusion provided a reference for the selection of salt-tolerant landscape trees in Shanghai coastal area.
