Valuing agricultural land standard prices based on agricultural land gradation and evaluation information system (ALGEIS)

Abstract

land is the most fundamental material of production, and is man's indispensable living condition for existence. Agricultural land prices reflect not only the uses of agricultural land, but the potential uses as well. This paper reviews the valuation on agricultural land prices in western developed countries and the development courses of agricultural land appraisal, especially valuation on agricultural land standard prices in China. The problems in the valuation at present are analyzed. According to the thinking of first gradating and then evaluating, Agriculture Land Gradation and Evaluation Information System (ALGEIS) based on Geographical Information Systems (GIS) is developed. As a case study, the proposed method is applied to value agricultural land standard prices in Yunan County, Guangdong Province, China. The case study shows that the proposed method is a practical and satisfactory one. The applications of achievements of valuation on agricultural land prices are discussed, which effectively promote the reform and development of land resources administration. Developing agriculture land gradation and evaluation information system based on GIS, can satisfy spatial, dynamic, quantitive and comprehensive requests in valuation on agriculture land.
