摘　　要：湖库等水体的基质类型和特性是影响水体生态系统恢复重建的重要因素,也是沉水植物苦草生长发育与稳定建群的基本条件。综述了湖库水体基质、湖库底泥与不同底质改良剂混合对苦草生长的影响;重点探讨了不同底质改良剂(生物炭、碎石、矿石及复合物质锁磷剂等)对苦草生长的影响。为选择最佳底质改良剂在原位生态修复领域中的应用提供了技术参考。The types and characteristics of substrate in the water of the lake reservoir and other water bodies are the important factors affecting the restoration and reconstruction of water ecosystems,as well as basic conditions for the growth and stable establishment of submerged macrophyte Vallisneria natans.In this article,we review the effects of substrate in the water of the lake reservoir and mixture of sediment in the lake reservoir and different substrate modifiers on the growth of Vallisneria natans.Moreover,we discuss the effects of different substrate modifiers(biochar,gravel,ore,and compound phosphorus-locking agent,etc.)on the growth of Vallisneria natans.The study provides the technical reference for selecting the best substrate modifier for the application of in-situ ecological restoration.
