水产养殖池塘沉积物有机质富集的环境效应与修复策略

沉积物有机质富集十养殖池塘的重要特征，有机质的分解将驱动营养物质的释放，其主要机制在于自身的矿化与底层厌氧状态的形成，后者将进一步促进有毒有害物质的产生和累积，进而影响水产品的产量与质量。因此，必须针对沉积物有机质富集的特征开展技师而准确的检测，同时采用选择性去除、原位氧化和生态修复相结合的方法对其实施有效地处置，以调节养殖池塘生态系统的结构与功能，最大限度地利用可再生资源和天然饵料，进而实现渔业生产与水环境的可持续发展.

Environmental Effects of Origanic Matter Enrichment and Restoration Strategy in Sediment of Aquaculture Ponds

Aquaculture pond was characterized by enrichment of organic matter in sediment. Decomposition of organic matter would drive nutrient releases from the sediment. The main mechanisms were its own mineralization and onset of bottom anoxia that enhanced formation of harmful substances further. All the facts would exert adverse effects on the quantity and quality of aquatic products. Hence, targeting the sediment organic matter enriched, timely and accurate monitoring must be performed. Accordingly, the organic matter could be effectively treated by selective removal combined with oxidation in situ and ecological remediation. As a consequence, the ecological structures and functions of the pond could be modified to make the full use of the regenerable energy and natural feeds. Therefore sustainable developments of aquaculture production and aquatic environment could be achieved.
