Land planning refers to the long-term arrangements for the rational use of land within a country or a certain region based on the prospects and needs of economic development. It aims to ensure that the use of land can meet the requirements of proportional development of various sectors of the national economy. The planning is based on the distribution and allocation of existing natural resources, technical resources and human resources so that the land can be fully and effectively utilized without wasting due to man-made reasons. The overall land use plan is the overall arrangement and layout of the development, utilization, management and protection of land in a certain area in space and time according to the requirements of the sustainable development of the country's social economy and the natural, economic and social conditions.
Through the overall land use planning, the country rationally allocates land resources in various industrial sectors. First, it allocates between agriculture and non-agriculture. Secondly, it allocates within agriculture and non-agriculture, such as planting, forestry, etc. within agriculture. Configuration between animal husbandry. In addition, the "Land Management Law of the People's Republic of China" also clearly stipulates: The state's overall land use plan stipulates land use and divides land into agricultural land, construction land and unused land. Strictly restrict the conversion of agricultural land into construction land, control the total amount of construction land, and implement special protection for cultivated land. Therefore, units and individuals using land must use the land strictly in accordance with the land uses determined in the overall land use plan.
According to the needs of national economic development, we measure the characteristics of various components and basic conditions of land in a certain area from a socio-economic perspective, compare and identify the quality, potential and suitable uses of the land to determine the most beneficial use. It is an indispensable basic work for land planning and the design of various land use programs. Many countries have their own methods and indicator systems for land evaluation. In order to achieve some form of standardization, the Food and Agriculture Organization of the United Nations (FAO) convened many international conferences for discussion and published the "Land Assessment Outline" in 2006.
The content involved in land evaluation is relatively extensive and requires comprehensive research from multidisciplinary knowledge of natural sciences, socioeconomic sciences and technical sciences. It can be carried out according to different regional scopes (such as the whole world, a country, a region, a production unit) or according to different land use types. The content of land evaluation varies according to different purposes. There are evaluations of land quality based on a certain production, evaluations of land production potential, and evaluations focusing on the suitability or restriction of a certain production.
