ABSTRACT
Land is valuable non-renewable resources. Since 21th, with the increase of population, the rapid development of economy, the contradiction between the limited land and the growing population is growing, people are not rational development and utilization of the land leads to land degradation degree aggravate, then affect the global environment.
China is a country with a large population, the total population accounted for about 1/5 of the world's population. However, our country cultivated area of about 95720000 hectares, ac- counting for the world total cultivated area of 7.7%. Since after twenty-first Century, our coun- try city plan to increase the process of city development, occupied a great deal of cultivated land. Therefore, strengthen economics a national policy of China's imminent.
Land use map is the map symbol shows the land use types and their distribution, reflecting the region land use thematic map structure. The 1:1 million map of land use actuality in our country at present the county land management departments for the land use planning, the im- plementation of arable land protection, provision of basic farmland, build land use database, and the implementation of basic graph element the annual land use change for work. The cur- rent land use map compilation of a variety of techniques, at present mainly is based on the ArcGIS platform, based on the MapGIS platform, the use of remote sensing image making land use map methods.
This paper mainly studies based on the ArcGIS software, 1:1 million map of land use in the national land survey results of datebase produced in Jingbian County of Yulin city in shannxi province. This paper introduces in detail the use of operation process of ArcGIS production of 1:1 million map of land use actuality, focuses on the specific details of the operation, common problems, as well as some drawing skill and experience. In addition, this paper also describes several other stage.Technology and method of making land using status of the popular. Finally, make the status of 1:1 million land use map target area.
KEY WORDS: Land use, 1:10000 map of land use, ArcGIS, Geographic Information System
