| Abstract | Tudiling Giant Panda Corridor, is the typical region of the Giant Panda Corridor habitat and the vegetation degradation in the upper Minjiang River basin, in which the effects of the existing disturbance regimes on plant communities after the vegetation restoration in the 1980s were assessed, and the distribution, composition and species diversity of restoration vegetation were analyzed using the transect sampling method, TWINSPAN and DCA. The results were as follows: At present, a total of 234 plant species representing 145 genera and 58 families were recorded at all plots. By means of TWINSPAN, DCA and disturbance identification, restoration vegetation could be divided into 6 major types (2 natural communities and 4 artificial communities accounting for different anthropogenic disturbances, respectively). DCA figure represented a disturbance gradient that increased from the bottom to the top along the second DCA axis. Species richness and Shannon-Wiener index in artificial communities markedly decreased as the intensity of disturbance increased. Heavy disturbance resulted in low diversity and inhibited regeneration because of the failure of tree establishment, growth, and survival during regeneration. Species diversity was higher in artificial undisturbed community than in natural undisturbed community. Therefore, high diverse mixed species in restoration and avoiding strong disturbance in this region can accelerate succession and maintain high species richness and diversity. |

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.
