| Abstract | This paper analyzes land use dynamic changes during latest 10 years in Huabei region based on RS and GIS. Huabei region includes four provinces (Hebei, Shanxi, Shandong and Henan), two cities (Beijing, Tianjing) and one municipality of Inner Mongolia. This region is Chinese center of politics, economy and culture, also important food supplies base. So the study of Huabei region is very significant. Using 1990, 1995 and 2000 TM images as a primary data source and processing by atmosphere and geometric correction, we get two dynamic coverages (1990-1995 and 1995-2000) by visual interpreting under MGE environment. Then we select Huabei region dynamic coverages. In ARC/INFO GRID, these coverages are changed into 100 m*100 m grid format. In the past 10 years, the farmland is increasing, especially in dry land; forest and grassland is decreasing and urban increases rapidly. Farmland shifting urban is the most land change; Secondly, grassland shifting farmland has a bigger proportion. According to land use zone, Huabei locates in two zones: one is huanghuaihai farmland shifting urban, which shows dry land is changing into county; The other is ecotone between agriculture and animal husbandry, which focus grassland shifting farmland in inner Mongolia. The past 10 years can be divided into two periods of time (1990-1995 and 1995-2000). Comparing the two periods of time, in huanghuaihai farmland shifting urban, the decrease of farmland and increase of urban in 1990-1995 is faster than that in 1995-2000; in the ecotone between agriculture and animal husbandry, the velocity of farmland increase in 1990-1995 is evidently greater than that in 1995-2000. And the ecotone between agriculture and animal husbandry has more obvious changes. |

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.
