| 随着生态城市、生态居住区及环
境建设的发展，景观水体已经成为城市建
设中不可缺少的组成部分。如何科学合理
地配置水生植物，已经成为亟需解决的问
题。本研究于2015年3—12月对重庆26个
都市区景观水体以及3个近郊区湿地公园
的水生植物进行了样地调查，其中都市区
景观水体选取14个典型代表，通过景观质
量指标和景观协调性指标对其进行景观评
价，同时将相关指标与近郊区湿地公园进
行对比。结果表明：研究区域内共有水生
植物42种，分属于22科，主要以湿生植物
和挺水植物为主，浮水和沉水植物应用较
少。在都市区景观水体中，仅重庆大学和大
渡口公园的时序多样性指数略高于观音塘
湿地公园和爱莲湖湿地公园，其余景观水
体指标均明显低于3个近郊区湿地公园。其
中6个景观水体水生植物配置综合评价等级为中等及以上，8个景观水体的景观评价等级为
差或极差。基于此，本研究分析了在景观水体水生植物应用过程中出现的问题，为进一步构
建健康的景观水系统提供科学的理论依据和技术支撑 |
