Based On The Mapgis Rural Land Use Database Construction And Updated Research

With the constant deepening of China's reform and opening up, development and resources will be more striking, while the reality in many areas of arable land and basic farmland of the exact number, spatial distribution is not very clear, severely restricted the relevant national development strategies, planning, science policy formulation and implementation. Therefore, land resources, find out the family property in today's is particularly urgent.For the land we have healthy is unclear, data is not real, it is difficult to adapt to the needs of economic and social development situation in the status quo, the State Council in 2007 made an important decision: A three-year period, the nationwide launch second national land survey, comprehensive, and accurate , grasp the status quo of land use. By combining the second land survey with Xinfeng practical work experience in rural areas, fully taking into account the requirements of the land management department to the county level, the study area, the county level, the use of rural land to build library project status information as data source, On the following aspects were studied:first, 1, for rural land use database construction, designed a platform based on 1:10000 scale MapGIS scientific, feasible and economic development of alignment options; 2, of rural land-use database update mechanisms and methods, management and security maintenance has done a more systematic studies; 3, for the process of building some of the key problems encountered in the analysis and Research , And the right MapGIS data into ArcGIS Data with C # language briefly interpreted code;4, the front of the building line of the program design applied to the Xinfeng County's rural land use database construction, finally able to meet the requirements of operational units, building a database for them to save a lot of unnecessary duplication of work. Because the construction of database is a complex system engineering, in the construction process many operation department will have some problems which are caused by the topology processing, map sheet Edge and image stitching. these two issues in depth study.Overall, this study are based on the temporal and spatial changes in rural land use database: 1 It can be quickly and accurately to provide an area of land use and distribution of various types of dynamic conditions; 2 for national economic development strategic decision-making to provide reference ; 3 for the land and resources management decision-making support and services; 4 It can be used to safeguard the legitimate rights and interests of ordinary people. Solution to the current efficiency in the management of land resources is not high, management issues such as inconvenience to the development and utilization of land resources, land resources assessment and planning tasks such as providing information support and decision-making basis.
