基于粗糙集理论的武汉市农业土地利用数据分析及规划决策研究

摘要:
[目的]以2001~2014年武汉市农业土地利用基础数据为研究对象,通过实证研究的方法证明粗糙集理论能够从大量的数据中发现客观规律,可以给决策者提供更多的决策支持。[方法]运用粗糙集理论将土地利用基础数据划分为条件属性和决策属性,对属性进行离散化和约简处理,析取决策规则,分析条件属性与决策属性之间的客观规律。[结果]粗糙集理论析取的隐含知识和模式,客观反映出武汉市的人均粮食产量变化与单位面积从业人口、人均用电量和单位面积化肥施用量等密切相关,且单位面积化肥施用量的影响最为显著。[结论]从粮食安全的角度考虑,应加强对化肥施用量与人均粮食产量定量关系的研究。

RESEARCH ON AGRICULTURAL LAND USE DATA ANALYSIS AND PLANNING DECISIONS BASED ON ROUGH SET THEORY IN WUHAN CITY

Abstract:
This paper analyzed the data of agricultural land use during 2001~2014 in Wuhan and the empirical research showed that the objective law could be drawn from a large number of data with the rough set theory, which could provide further support for decision makers. Using the rough set theory, the basic data of land use was divided into the condition attributes and the decision attributes, and the attributes were discretized and reduced. The decision rules were extracted and the objective laws between the condition attributes and the decision attributes were analyzed. The results showed that disjunctive hidden knowledge and patterns based on the rough set theory can reflect the per capita grain yield in Wuhan and had a close relationship with working population, electricity consumption and the amount of chemical fertilizer per unit area. Fertilizer consumption contributed the most to the gain yield in unit area. Therefore, more research should be dedicated to the study of the quantitative relationship between fertilizer application and per capita output of grain with the concern of the food safety.
