As a transition zone between the terrestrial ecosystem and the marine ecosystem, coastal intertidal wetland provides an important place for material circulation and energy exchange, and it is nature's most precious resource. The ecological health of intertidal wetlands is an important prerequisite for sustainable green development. The material exchange function objectively and accurately reflects the material balance and ecological health of intertidal wetlands in the coastal zone. This paper uses remote sensing, geographic information technology, and model methods to objectively and accurately assess the temporal and spatial changes in the material exchange function of intertidal wetlands, providing a feasible method for studying the material exchange function of coastal wetlands. The material exchange capacity of wetlands in intertidal zones is affected by many factors, such as vegetation, topography, and base soil. After the invasion of the alien species , the elevation of the beach increased by 0.3 m. The elevation of the beach rose by 0.14 m. The average elevation of increased by 1.24 m. The material exchange capacity of the intertidal zone decreased by 25%. The functioning of the material exchange between sea and land changed significantly, and the area with a high level of material exchange function capacity was reduced by 71%.
作为陆地生态系统和海洋生态系统之间的过渡带，滨海潮间带湿地为物质循环和能量交换提供了重要场所，是大自然最宝贵的资源。潮间带湿地的生态健康是可持续绿色发展的重要前提。物质交换功能客观准确地反映了滨海潮间带湿地的物质平衡和生态健康状况。本文利用遥感、地理信息技术和模型方法，客观准确地评估了潮间带湿地物质交换功能的时空变化，为研究沿海湿地物质交换功能提供了可行的方法。潮间带湿地的物质交换能力受到植被、地形和底土等多种因素的影响。入侵外来物种后，海滩的海拔升高了 0.3 米。海滩的海拔上升了 0.14 米。平均海拔上升了 1.24 米。潮间带的物质交换能力下降了 25%。陆海之间物质交换的功能发生了显著变化，物质交换功能高的区域减少了 71%。
