红树植物是热带、亚热带海湾河口优势植物种,是该生态系统的重要初级生产者,对维护海湾河口地区的生态平衡起着十分重要的作用。随着江河流域现代工农业的迅猛发展,沿海城市人口与经济的快速增长,多种因素使河口海湾区的环境污染日趋严重,严重影响着区域生态系统的健康与发展。红树林作为一种海岸潮间带森林生态系统,对海湾河口区域的污染具有较高承载力和耐受性。 本研究以在我国分布较广的白骨壤(Avicenniamarina)为试材,探讨在不同光照强度条件下,红树林湿地常见的重金属污染物Cd对白骨壤植株生长、叶绿素、Cd、Fe和Mg含量、可溶性糖、丙二醛和谷胱甘肽含量、抗坏血酸过氧化物酶活性等的影响,以求探讨不同...Mangroves are dominant species in tropical, subtropical estuarine. They are important primary producers in the ecological system, which plays an important role in maintaining ecological balance in the estuary. With the rapid development of the industry and agriculture in modern river basin and the rapid growth of the coastal of population and economy, human disturbance is becoming more and more se...学位:理学硕士院系专业:生命科学学院_生态学学号:2162010115229
