| Abstract | The Liulin karst spring flow has been declining since 1950s, and the main cause to the attenuation is more and more intensive human activities and instructions. By using the Grey system model piecewise, this paper focuses on analyzing the effects of anthropogenic activities to hydrological process of Liulin karst spring statistically. In the first stage (1957–1973), Liulin Springs flow is only affected by climate; in the second stages (1974–1996), Liulin Spring flow is affected by climate and human activities, and not steady; in the third stage (1997–2009), Liulin Springs flow is affected by climate and human activities, and steady. Then through scientifically comparing, we analyzed the effect of human activities to hydrological process of Liulin Spring by using Grey relational analysis and GM model with time lags. The results illustrate that (1) the lag increases from 0 to 4 years; (2) the most important recharge to karst flow is precipitation (3) it is human activities that caused the attenuation of spring flow after 1974, which means that human activities have significantly negative influences on the supplement of precipitation to Liulin Spring. |

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.
