Abstract | taking Landsat5/TM images of 1988, 1997 and 2005, this paper used RS and GIS to analyze the changes of ecological environment effects of land use / cover change (LUCC) during the recent 17 years of the study area. The results indicate that: swamp land shows obvious decreasing trend and decreases $1674km^{2};$ dry land and paddy land shows strong increasing trend and increase $377km^{2}$ and $1338km^{2}$ separately. There is a small growth rate of woodland, waters land and buildings, $290km^{2},$ $47km^{2}$ and $32km^{2}$ separately. While, eco-environment effects evaluation by typical remote sensing index of LUCC has no significant change. Comprehensive evaluation results show that highly ecological quality area with quality scores between 7.6308 and 8.9825 accounts for a larger proportion, respectively 90.92%, 89.85% and 90.1% in 1988, 1997 and 2005. There is a slight decline in the eco-environment quality from 1988 to 1997 and comparable stable increase from 1997 to 2005. Eco-environmental high-quality zone, sub-high quality zone and medium quality zone show a decreasing trend, while the medium-low quality zone and low quality zone show an increasing trend during 1988–2005.The overall eco-environmental quality has changed little in the study area. |

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.
