Marine litter surveys were carried out to determine the role of mangroves as a sink for litter. General litter density in the mangroves was 0.088 ± 0.076 items m, composed mainly of plastic (85.9 %). Higher litter densities occurred in the middle (0.162 ± 0.150 items m) compared to the landward (0.066 ± 0.049 items m) and the seaward zones (0.036 ± 0.028 items m), indicating the important role played by the middle zone in providing a sink for litter from both land and sea-based sources. Landward zones were a sink for heavier litter from land that could easily be trapped by mangrove roots (plastic and clothing). The middle zones retained mainly the litter that are not easily trapped by the mangroves' roots in seaward and landward zones, particularly soft plastics. The seaward zones acted as a sink for litter from sea-based sources mainly marine and fishing gears, and materials used for fishing and boat repairs.
开展了海洋垃圾调查，以确定红树林作为垃圾汇的作用。红树林中的一般垃圾密度为0.088±0.076件/平方米，主要由塑料组成（85.9%）。与向陆区（0.066±0.049件/平方米）和向海区（0.036±0.028件/平方米）相比，中区的垃圾密度更高（0.162±0.150件/平方米），这表明中区在为来自陆地和海洋来源的垃圾提供汇方面发挥了重要作用。向陆区是来自陆地的较重垃圾的汇，这些垃圾很容易被红树林根系困住（塑料和衣物）。中区主要留存了在向海和向陆区不易被红树林根系困住的垃圾，特别是软塑料。向海区是来自海洋来源的垃圾的汇，主要是海洋和渔具以及用于捕鱼和船只维修的材料。
