摘要
农作物估产是我国长期以来进行的一项重要课题。为此,探讨了空间数据仓库的特征、体系结构,对现有农作物估产方法进行了评价。鉴于农作物估产的影响因素的复杂性,引入空间数据仓库技术,并且建立了多维数据模型,来进行农作物估产的研究,为农业决策部门提供参考依据。
During the past years, crop yield estimation has gained increasing concerns within scientific literature of china. The paper inquired into the characteristic, system architecture of spatial data warehouse and valued crop yield estimation methods we have now. Since many factors influence agricultural estimating, a trial is suggested to apply spatial data warehouse technology in the research of crop yield estimation and modal of multi-dimensions were built. Thus agricultural decision-making department can obtain reference.
