本文以环渤海滨海盐碱城市为研究对象,阐述传统城市绿地系统规划方法的不足,以满足生态系统服务功能为基本出发点,从土壤本身的属性入手,进行土壤盐碱化景观安全格局分析。笔者建议,应根据土壤上适宜的植物群落将不同土壤含盐量区域的绿地生境进行预先选择,避免在绿地的建设中盲目地消耗经济和破坏生态,这有利于保护盐碱地地区脆弱的生态环境和生物多样性。
This paper takes the coastal salinization and the city of the Bohai Sea as the research object, elaborates the insufficiency of traditional urban green space system planning methods, and takes the ecosystem services as the basic starting point. Starting from the properties of the soil itself, the landscape security pattern of soil salinization is analyzed. The author suggests that the selection of green habitats in different salinities of soil should be preselected according to the suitable plant communities on soil so as to avoid blindly consuming the economy and damaging the ecology in the construction of greenbelt, which is good for protecting the fragile ecological environment of saline-alkali land areas and Biodiversity.
