竹类植物在黄河三角洲盐碱地生态修复中的应用进展

Application of Bamboo in Ecological Restoration of Saline-alkali Land in the Yellow River Delta

黄河三角洲地区受地势低平、海水易内侵、蒸发量大于降雨量等因素影响,形成了大量盐碱地,对该地区盐碱地进行生态修复具有重要的生态安全意义。文章综述了黄河三角洲盐碱地成因、盐分主要构成、盐胁迫对植物尤其竹类植物的影响,以及竹类植物在滨海盐碱地应用种植情况,认为竹类植物具有很好的观赏性和生态及经济价值,在滨海盐碱地有种植先例和研究报告,种植技术成熟,可以通过筛选、引种、驯化耐盐碱竹类植物,在黄河三角洲盐碱地生态修复中应用。

A large amount of saline-alkali land has formed in the Yellow River Delta due to the influence of low and flat terrain,seawater intrusion,higher evaporation than rainfall,and their ecological restoration is of important ecological security significance.The paper reviews the cause of saline-alkali land formation in the Yellow River Delta,the main composition of salt,the effect of salt stress on plants especially bamboos,and the application and planting of bamboos in coastal saline-alkali land.It is thought that bamboos has good ornamental,ecological and economic value.There are precedents and research reports on planting bamboos on coastal saline-alkali land,and the planting technology is mature.Bamboos can be applied in the ecological restoration of saline-alkali land in the Yellow River Delta by screening,introducing and domesticating saline-alkali resistant varieties.
