摘要:
对30年来天津滨海新区重盐碱土绿化研究进展进行 梳理和总结。分析了天津滨海新区绿化建设面临的严峻的盐渍 环境、有限的地下生长空间、贫乏的绿化植物资源等挑战,制 定的因应策略,以及针对性开发创建的“浅密式”暗管排盐工 程技术与相关配套技术、适生植物资源开发利用技术、绿地水 肥盐精准管控技术等盐碱土绿化技术体系。最后概述了滨海新 区重盐碱土生态绿化建设取得的成效,以期为中国盐碱地区城 市生态绿化建设提供借鉴和参考。

Abstract:
In this paper, the progress of heavy saline-alkali soil greening in Tianjin Binhai New Area over the past 30 years was reviewed. Firstly, the formidable challenges faced by the heavy saline-alkali soil greening in Binhai New Area, such as severe saline environment, limited underground growth space and poor plant resources, were analyzed, and the coping strategies were elaborated. Subsequently, the special soil greening technologies of saline-alkali were introduced such as the "shallow closely spaced" subsurface drainage technology and related supporting technology, the development technology of suitable plant resources, and the precise control technology of water, fertilizer and salt in green space. In the end, the achievements of ecological greening of heavy salinealkali soil in Tianjin Binhai New Area were summarized. This will provide useful reference for urban ecological greening construction in saline-alkali areas in China.
Key words:  landscape architecture  heavy saline-alkali soil  greening  soil improvement  garden plant  green space management
