摘要
城市公园中的水生植物景观营建与水生态修复是公园水环境治理的关注重点。在中国很多城市的公园水体中,人工种植了具有观赏性的外来物种水盾草(Cabomba caroliniana),而水盾草生长范围的不断扩张对土著水生植物物种的存活、物种多样性和分布格局都会产生较大的影响,还会进一步影响水体的质量。主要通过物理、化学和生物防治措施来控制水盾草的无序蔓延。然而,如何彻底解决水盾草的反复爆发问题,使水生生态系统受到的负面干扰最小,仍然是水盾草防控工作的难点。综合分析了水盾草的生理生态特性、入侵途径和生态危害,阐述了影响水盾草生物量的主要生物和生态环境因素等的研究进展;从园林景观营建过程与后期水体生态稳定性维护管理视角,结合水盾草生态控制的基本理论和方法,提出了对水生生态系统中的土著植物、附生藻类和生态环境中非生物因子进行综合生态调控的建议,以期解决上述难点问题,并且为稳定城市公园的水生植物景观和治理水盾草扩散提供借鉴。
Aquatic plant landscape construction and water ecological restoration in urban parks are the focus of attention in the management of water environment of the parks.In many urban parks in China,the exotic species Cabomba caroliniana has been planted artificially in the water bodies.The expansion of the growing range of Cabomba caroliniana has a significant impact on the survival,species diversity and distribution pattern of indigenous aquatic plant species,and further affects the quality of water bodies.The reckless spread of water hyacinth is mainly controlled by physical,chemical and biological control measures.However,how to completely solve the problem of repeated outbreaks of Cabomba caroliniana,so as to minimize the negative disturbance to aquatic ecosystems remains a difficult task in the prevention and control of Cabomba caroliniana.This paper comprehensively analyzes the physiological and ecological characteristics,invasion pathways and ecological hazards of Cabomba caroliniana,and describes the research progress of the main biological and ecological environment factors affecting the biomass of Cabomba caroliniana.From the perspective of landscape construction process and the later period of water ecological stability maintenance and management,the paper puts forward proposals of comprehensive ecological regulation and control for the native plants,epiphytic algae,and the non-biological factors of the ecological environment in aquatic ecosystems.These proposals aim to solve the difficulties mentioned above and provide a reference for stabilizing the aquatic plant landscape and managing the proliferation of Cabomba caroliniana in urban parks.
