基于MATLAB聚类法的耕地质量的差异分析

Application of Cluster Analysis Based on MATLAB in Research of Cultivated Land Quality

【目的】耕地是农业生产的基本要素,加强耕地质量建设,提高耕地综合生产能力是实现社会经济可持续发展,保障国家粮食安全、保障土地资源安全的重要途径。通过对2012年阿勒泰市各乡镇关于耕地质量的数据进行研究,分析造成阿勒泰市各乡镇耕地质量差异性的原因。【方法】运用MATLAB不同聚类方法对阿勒泰市各乡镇的耕地质量数据进行聚类分析,选取符合阿勒泰市各乡镇耕地质量情况的分析方法。【结果】根据限制性因素对阿勒泰市各乡镇的耕地质量分类进行分析,得到四种分类结果。【结论】通过耕地质量研究,查清阿勒泰市耕地位置、范围和面积,全面掌握阿勒泰市耕地数量、质量及分布状况,为提高阿勒泰市各乡镇耕地质量提出相关建议。

[ Objective] Cultivated land is the basic elements of agricultural production, to strengthen the construction of cultivated land quality, improve the overall production capacity of cultivated land is the realiza- tion of social and economic sustainable development, to ensure national food security, an important way to pro- tect the safety of land resource. The aim of this article is to analyze the differences and the reasons to the quali- ty of the cultivated land in various villages and towns of Altay city by researching of the basic data about the quality of the cultivated land in 2012. [ Method] In order to choose appropriate method for analyzing the quali- ty of the cultivated land in various villages and towns of Altay city, the different ways of cluster analysis was carried out by using MATLAB software. [ Result ] The quality classifications of the cultivated land in various villages and towns of Altay city can be analyzed according to the restrictive factors. Four kinds of classification results are obtained. [ Conclusion ] Through farmland quality research, find out Altay land position, scope and area, a comprehensive grasp Altay cultivated land quantity, quality and distribution, Relevant suggestions are put forward for improving the quality of the cultivated land in various villages and towns of Altay city.
