Study on Demarcation of Basic Farmland Based on GIS — A Case Study of Fogang County

Abstract:

The demarcation of basic farmland scientifically is important to cultivated land protection, agriculture-economy development, and regional sustainable development. This paper took Fogang County as an example, calculated the amount of basic farmland protection and exclusion and then quantified the addition amount; established the evaluation system of farmland; used Analytic Hierarchy Process (AHP) and entropy method to determine the index weights; prioritized the selected cultivated land using GIS and Technique for Order Preference by Similarity to an Ideal Solution (TOPSIS); and then combined with the addition amount to optimize the basic farmland spatially. The study result proved that the demarcate method of basic farmland was feasible, and can provide scientific and technological support for basic farmland planning.
