Land Reclamation Planning Related Datum Compilation Technique Research

Land management is in accordance with the general land use planning, field, river, road, forest, village comprehensive improvement, improve the quality of cultivated land, increase effective arable land, improve agricultural production conditions and ecological environment. Land reclamation planning in the process of preparation, approval and implementation involves a large number of datum, and needs to be updated in real time.And ArcGlS has powerful graphics editing functions and spatial data analysis.It is widely used in land planning and design. In the concrete work of land renovation plan, thematic maps are more intuitive, strong expressive force than other forms, and have the advantage of easy to understand. Thematic maps datum aid planning text and illustration with features and guiding role, many degrees in public participation in environment is higher and higher, thematic map and integrating promotion and use, so the mapping quality has great influence on land renovation plan.Using the results of XX city’s secondary land survey as experimental data for this thesis, combination with the cartography and land management related theory knowledge, using the ArcGIS software platform and the function of map symbol design, we designed the symbol library satisfies the requirement of land reclamation planning each element of the system. And further research the function of mapping function of note, through in-depth study, map production process meets the demand of the land reclamation planning in the note.The main contents are as follows:1. Based on the general land use planning symbol library and the advantage of ArcGIS self having the symbol library, we make a set of meet the requirements of the procedures for land reclamation symbol library system through adding and deleting them. When making the symbol library class coding, in order to facilitate later drawing work, has the state land two adjustable geographical elements in topographic map schema standard classification and coding completely, reaches in feature symbol filled by object attribute code automatic matching with the corresponding symbol encoding implementation purposes.2. According to the project area land use present situation and combining with field survey data, we evaluate of various counties (districts) of new potential of cultivated land size according to relevant theories of land management. Due to large amount of data, on the basis of the visio studio2008environment I developed the potential measurement tools after studying the potential size of the calculation method. 3. On the base of the preliminary work, based on the ArcMAP software, we make the land utilization present situation chart in use of the second national land survey results. We calculated the potential of new land according to the different types of application potential evaluation, and made a thematic map.
