摘要: 为探讨沿海防护林树种适宜性以及沿海防护林的生态效应,选择上海海湾森林公园和金山化学工业区防护林为研究对象,通过建立AHP模型评价指标体系,对防护林树种的适宜性进行评价;同时,对采集的土壤样品进行测定,以此分析防护林的改土效果和生态效应。结果表明,营建沿海防护林能较好地促进土壤脱盐,提高土壤有机质含量,改善土壤结构;防护林还有助于增加空气负离子数量,调节大气温湿度,生态效应比较显著。

Abstract: This research focused on adaptability and ecological benefits of coastal protective forests in Shanghai. The coastal protective forests growing at Haiwan Forest Park and Jinshan Chemical Industry Park in Shanghai were chosen as the research objects. By building an AHP model of evaluation index system, the suitability of tree species for protective forest establishment and their ecological effect were studied. The results showed that coastal protective forest could decrease soil salinity as well as enhance soil improvement through increasing organic matter content. Moreover with forests growing, the air negative ions also increased and atmosphere temperature and humidity were improved, which means that coastal protective forests have an obvious effect on improving the environment.
