| Abstract | Based on the inter-relations between resources system, environment and ecosystem potential economic values under the frame of marine ecosystem, a marine ecosystem nonlinear system dynamics model is established in this paper. Then the marine ecosystem is simulated by the use of MATLAB software at a certain region, which indicates that the marine ecosystem serves the function of self decontamination towards the influence of light-level contamination of plastic debris to maintain a stable state, and that when the rates of resources exploitation or the rates of plastic debris into the ecosystem from the external environment belong to a reasonable interval which can be calculated by the model mentioned above, the marine plastic debris concentration would be stable and achieve dynamic balance; on the contrary, if the parameters exceed a certain value, and if no measures are taken, the marine plastic debris concentration would increase dramatically, the marine ecology resources would become exhausted, and the ecosystem would lose its potential economic value. Finally, a pre-warning mechanism for the marine ecosystem is set up and some suggestions are given in order to help researchers and ultimately government policy makers to understand the severity and potential global impact of the situation. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
