| Abstract | Ecological security is the core and basis of sustainable land utilization. Study of land ecological security has become a forefront area in study of sustainable land utilization. Based on Pressure-State-Response model, the paper constructed an evaluation index system of land ecological security. The index system was composed of land resource pressure, land resource state and cultural environment response. Then the paper established an evaluation model of land ecological security based on attribute recognition theory. Finally the paper evaluated land ecosystem conditions of the nine cities along the Changjiang River in Anhui Province in 2007. The sequence of the cities is: Anqing≪Chaohu≪Chizhou≪Chuzhou ≪Wuhu ≪Tongling≪Maanshan≪Hefei≪Xuancheng. Maanshan, Hefei, Tongling and Xuancheng belong to “critically secure” grade and the other five cities belong to “relatively insecure” grade. Secure conditions of the three elements belong to “critically secure” or “relatively insecure” grade. The results can provide references for solution of land ecological problems. |

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.
