| Abstract | Air pollution is one of the most serious environmental problems in the world. At present, air quality models are focused on pollutant prediction and source discovery, lacking the analysis of transmission paths and independent monitoring station characteristics. In this paper, complex network based on statistics is applied in air quality field and a new model is proposed based on it. Path existential network and pollutant transmission path set are generated integrating the data of air quality and meteorological monitoring stations. Mapping relation is established among them to generate real-time air quality network, then a complex network in a whole cycle is obtained through statistics. Experiments based on PM2.5 pollution data in Jing-Jin-Ji region demonstrate the rationality of the proposed model. Three characteristics of complex network: scale-free, small-world and community aggregation are verified. Characteristic detection and key station mining provide guidance for air protection in reality. In the network, we can reduce pollution effect by blocking a few important transmission paths between communities. The results provide reference for site selection of new monitoring station, dynamic evolution and pollution degradation. |

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.
