【摘要】：我国的耕地资源存在较为明显的缺陷,耕地质量不高,耕地利用效率低以及后备耕地资源储量的严重不足等现象,再加上我国耕地资源的不断减少,已经严重影响了我国农业经济的发展。为提高农产品的产量,通过合理利用有效资源提高农产品收益,必须改善我国耕地资源的利用效率,最大限度的发挥我国耕地资源的潜力。对耕地进行高效科学耕种,就必须了解耕地的土壤信息和质量。目前我国在耕地有效利用方面的研究已经取得了很大程度的进展,如利用层次分析法和模糊综合评价方法进行的耕地地力评价,以及测土配方施肥等高效的耕地种植技术,都为改变我国耕地质量提供了合理的技术支持。本文利用ArcGIS Engine组件技术和ArcSDE的存储技术,建立耕地资源信息管理系统。通过对组件式系统开发开发的原理和特点、ArcGIS Engine二次开发的优势及特点以及ArcSDE空间数据库引擎的优点等进行阐述,讨论了系统开发的基本原理。对耕地资源信息的空间信息和属性信息进行统一化和规范化处理,利用ArcSDE存入系统的底层数据库。通过ArcGIS Engine进行耕地资源信息管理系统的构建,系统通过空间查询子系统,属性查询子系统、耕地地力评价查询子系统和其他辅助子系统组成耕地资源信息管理系统。系统针对非相关专业的用户进行开发,在这种情况下,系统界面设计需简洁大方,用户通过简洁明了的空间查询、属性查询以及耕地地力等级信息的查询,对相关耕地的地力评价信息获得了解,为用户在耕地的科学种植方面提供参考依据,为进一步了解科学种植奠定了基础。
[Abstract]:There are obvious defects in cultivated land resources in our country, such as low quality of cultivated land, low utilization efficiency of cultivated land and serious shortage of reserves of reserve cultivated land resources, in addition to the continuous decrease of cultivated land resources in China. Has seriously affected the development of our agricultural economy. In order to increase the yield of agricultural products and improve the income of agricultural products through the rational utilization of effective resources, we must improve the utilization efficiency of cultivated land resources in China and give full play to the potential of cultivated land resources in our country. In order to cultivate cultivated land efficiently and scientifically, we must know the soil information and quality of cultivated land. At present, great progress has been made in the research on the effective use of cultivated land in China, such as the evaluation of cultivated land fertility by using AHP and fuzzy comprehensive evaluation methods, and the efficient cultivated land planting techniques such as soil testing and fertilization, etc. For changing the quality of cultivated land in China to provide reasonable technical support. In this paper, the information management system of cultivated land resources is established by using ArcGIS Engine component technology and ArcSDE storage technology. This paper expounds the principle and characteristics of component system development and the advantages and characteristics of ArcGIS Engine secondary development and the advantages of ArcSDE spatial database engine, and discusses the basic principle of system development. The spatial information and attribute information of cultivated land resources are unified and standardized, and ArcSDE is used to store the underlying database of the system. The information management system of cultivated land resources is constructed by ArcGIS Engine. The information management system of cultivated land resources is composed of spatial query subsystem, attribute query subsystem, cultivated land fertility evaluation query subsystem and other auxiliary subsystems. The system is developed for non-related professional users. In this case, the system interface design needs to be concise and generous. The information of land fertility evaluation of cultivated land is understood, which provides a reference for users in the scientific cultivation of cultivated land, and lays a foundation for further understanding of scientific planting.
