| Abstract | Oasis is a specific landscape that exists with deserts in arid regions. In this paper, the oasis landscape changes in middle-lower reaches of Shule River basin had been analyzed. Using the Landsat TM imagines of June in 1987 and August in 2003 as the digital sources, the vector and grid landscape maps of distributions of the study area were derived. The dynamics variation of the oasis landscape in that basin was got on the basis of the software of ArcGIS 9.0, and the forecast on the dynamic variation of landscapes was executed using the software of the Matlab 6.3. At the same time, the eco-environmental effects of landscape change had been analyzed. The results showed that the landscape change with the main feature of increasing cropland area led to a series of ecological environment problem, such as deterioration of water quality, natural vegetation decreasing, and the eco-environmental system deteriorating. Human activities, especially in relation to water utilization and population increment, have gradual became the most active and dominant driving factors in the landscape change. |

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.
