摘要
对河口湿地生态系统所受到的自然干扰和人为干扰进行了系统辨识。重点分析了海平面上升、台风暴潮等自然干扰,围垦、大型海岸工程(填海、码头建设等)、环境污染和保护区建设等人为干扰对河口湿地生态系统结构和功能的影响。通过分析认为:人为干扰已成为河口湿地景观演变的主要驱动力,河口湿地生态系统健康发展需要加强对各种干扰的合理调控。
Natural disturbance and human_caused disturbance of estuary wetland ecosystem were identified. The effects of natural disturbance such as sea level rise, typhoon and storm tide, and human_caused disturbance such as reclamation, coastal engineering, environmental pollution and natural conservation area construction, on the structure and function of estuary wetland ecosystem were analyzed.The results show that human_caused disturbance has become the main driving force for estuary wetland landscape evolution.The healthiness of estuary wetland ecosystem may be realized through regulating and controlling all types of disturbance.
