【 摘 要 】

From November 2015 to August 2016, this paper conducted an investigation into the classification of the litter on the Heishijiao beach in Dalian, and made a comprehensive evaluation of the litter pollution on the beach in different seasons. According to the results, the litter on the Heishijiao beach in Dalian mainly come from human's offshore activities and other wastes, and spring is the season which witnesses the largest quantity of litter resulting from the activities. Most of the fragmental wastes are glass, plastic and paper, while there is a little metal, rubber and wooden products. On the Heishijiao beach, most of the fragmental litter are small, followed by medium and large ones; outsized wastes are rare. The quantitative density of litter is highest in winter (9.0items/m2), with the average quantitative density of 4.6 items/m2; the qualitative density of litter is highest in spring (8 g/m2), with the average qualitative density of 6.0 g/m2. The results of the comprehensive evaluation show that the litter pollution on the Heishijiao beach stays between "Average" and "Unsatisfactory".
