Suitability evaluation of characteristic cash crops has become an important direction of agricultural regionalization research in recent years. Climate conditions, terrain conditions and soil conditions are important factors that determine the distribution and quality of famous and excellent agricultural products. The purpose of planting suitability evaluation is to make rational use of natural resources on the basis of fully evaluating the land potential, and then optimize the production layout. GIS technology is a new and high technology which is being widely used and has strong spatial analysis capability. Combining with the planting suitability evaluation model, it can give full play to the mapping performance and spatial analysis capability. Therefore, the purpose of this paper is to explore the development suitability evaluation based on GIS on the basis of studying the theory of cash crop planting, analyze the planting suitability evaluation system based on multiple linear regression algorithm, and explore the advantages and disadvantages of using this technology. This article will use the research method of specific analysis of specific problems to make data comparison and draw a conclusion. Through theoretical innovation and exploration, we can find a suitable model to promote the rapid development of cash crops. The research results show that the key to distinguishing economic crops with special features according to local conditions is to enhance the position of the main management body. After investigation and analysis, it is ensured that the appropriate management mode and method can account for 36% of the optimized planting path.Therefore, combined with the characteristics of the current era, the use of geographic integrated information system, fully absorb the transformation and actively innovate and improve the level of agricultural cultivation. Analysis of different application difficulties and exploration of development prospects, provide real-time digital planting production information for growers, thus developing land potential, realizing high crop yield and innovation and integration guided by these theories, provide valuable experience for wide application of geographic information system technology, and realize sustainable development of regional economic structure and ecological environment.
