滨海盐碱地适生植物筛选研究——以金山围填海项目为例

Study on the Selection of Suitable Plants in Coastal Saline-alkali Land——A Case Study of Jinshan Reclamation Project

滨海盐碱地绿化除了需要对土壤进行改良,更重要的是选择适生植物,尤其在项目初期,不仅可以降低施工成本,还能减少人为干预,符合植被演替的一般规律,更自然生态。以金山围填海项目为例,利用项目围堤、吹填之际,在临近的鹦鹉洲湿地试验区开展适生植物筛选研究,定期观察、记录苗木生长情况,并采用层次分析法对栽种在盐碱地上的植物进行综合评价,筛选出适宜生长的苗木,为金山围填海项目的后续绿化建设及其他滨海盐碱地绿化建设提供技术支撑和参考。

In addition to soil improvement,it is more important to choose suitable plants for greening in coastal saline-alkali land,especially in the early stage of the project,not only to reduce the construction cost,but also to reduce human intervention,in line with the general rule of vegetation succession,more natural ecology.In this paper,taking Jinshan reclamation project as an example,during the embankment and reclamation engineering,the suitable plants were selected and studied in the adjacent experimental area of Yingwuzhou wetland.The growth of plants was observed and recorded regularly,and the plants planted on the saline-alkali land were evaluated comprehensively by AHP,and the suitable plants were selected.Technical support and reference are provided for the subsequent greening construction of Jinshan reclamation project and other coastal saline-alkali land greening construction.
