滨海盐碱湿地景观建设的基本原则--以天津光合谷湿地公园为例

Basic Principles of Coastal Saline Alkali Wetland Landscape Construction:Taking Tianjin Guanghegu Wetland Park as an Example

滨海盐碱湿地的利用已成为近年来沿海城市生态建设的重要组成部分,但是由于在开发利用过程中没有重视其特有的立地条件,未能进行科学合理的景观设计和针对性的盐碱地植被构建,导致在景观建设过程中造成了巨大损失。本文分析了天津光合谷湿地公园前期景观建设失败的原因,探讨了滨海盐碱湿地景观建设的3条基本原则,即排盐和控盐是关键、改良土壤是基础、植物选择是重点。只有盐、土、植物的系统性、针对性设计才能建造可持续的滨海盐碱湿地公园。

The utilization of coastal saline alkali wetland has become an important part of the ecological construction of coastal cities in recent years.However,huge loss caused in the landscape construction process because of neglect of specific soil conditions,and no pertinence landscape design and scientific saline vegetation construction.This paper explored the basic principles of coastal saline wetland landscape construction by discussing the failure causes of the early landscape construction in Tianjin Guanghegu Wetland Park,and concluded three basic principles :salt removal and salt control were the key factors;soil improvement was the basis;plant selection was the key point.Only systematic and specific design considered of salt,soil and vegetation can build a sustainable saline-alkali wetland park.
