Abstract: In China's cash crops, pecans are a very important part of it, it has multiple values, so in the current process of cash crop cultivation in China has been very widely cultivated and applied, in the current coastal areas of China, pecan industry has achieved rapid development, its planting area further expanded, more effectively enhance its economic value, many experts and scholars on its biological characteristics and so on, and further attention to further research and development of corresponding reproductive technology to explore and analyze, The corresponding more scientific and efficient cultivation methods can be used to show better planting efficiency. Based on this, this paper focuses on the analysis of GIS technology-based pecan growth suitability evaluation and other related content.

Key Words: Pecans; Fuzzy comprehensive evaluation; Membership function; Suitability evaluation

1 基于GIS山核桃適应性生长评价研究之目的

加强GIS基础之上的山核桃适应性生长评价研究的主要目的就是希望能利用山核桃产区的具体环境,注重做好全面深入的调研和分析工作,进一步把握各类内容,然后通过信息技术的有效作用和多种技术的协同推进,以此把握相对应的影响因素和关键因子,同时对于山核桃的生物学特征等等进行充分的分析,这样可以更有效地掌握内在的规律,然后进一步体现出应有的管控效果 [1]。
