【摘要】 现代化的农业资源信息系统是以遥感(RS)技术、地理信息系统(GIS)技术、全球定位系统(GPS)技术为核心的现代空间信息处理系统。这些技术的互相集成应用,能够极大的提高农业生产的主动性,使单纯的依靠土、水、气、热等自然资源的传统农业,更多的注入社会经济、现代科技、市场信息等资源。 江津作为重庆市柑桔产业发展条件较为突出的地区,无论是气候条件还是土壤条件都适宜种植柑桔,但是过去大多数柑桔园都是建在丘陵山地,立地条件差,果园基础设施差,管理水平低,抵御自然灾害能力弱,柑桔产业布局极不合理,严重制约柑桔产量和品质的提高,影响果农的增收和农村经济的健康发展。 随着柑桔产业信息化的发展,运用先进的3S(GIS、GPS、RS)技术、数据库技术研究柑桔的产业化布局是世界柑桔产业发展的一个趋势。重庆江津市柑桔生产管理信息系统的建立不仅可以为江津柑桔产业的发展提供布局决策依据,还可以为江津市的城乡规划、资源勘查、环境保护、河道整理等提供基础的数据资料,这对于江津市的经济发展、生活水平的提高和生态平衡建设都具有举足轻重的作用。 本研究在查阅大量相关的文献资料的基础上,采用野外调查、室内分析等方法,运用GIS技术,建立了江津市柑桔生产管理基础数据,结合ArcObjects,建立了重庆江津市柑桔生产管理信息系统和相应的地理数据库,就重庆江津市柑桔生产基地布局的大气污染物、均温和土壤条件等一系列指标进行了系统而有益的研究,最后得出了江津市柑桔产业布局图。在论文进行过程中取得了以下一系列成果: (1) 在比较各种地理数据模型的基础上,采用面向对象的数据模型——Geodatabase(地理数据库)数据模型,克服了以往CAD和Coverage数据模型的一些弊端。 (2) 在比较各种GIS开发方式的基础上,采用了ArcGIS8.3中的组件开发包ArcObjects,在ArcGIS内部环境下进行开发定制,扩展了ArcGIS的功能,使得系统的使用更加简单、直观。 (3) 系统集成了包括地形、土壤、土地利用现状、气候、大气、灌溉水、饮用水以及土壤采样调查点等在内的各项基础数据和柑桔生产管理调查数据以及柑桔生产管理和病虫害防治的多媒体数据,这些数据为柑桔生产管理、决策支持提供了雄厚的基础。 (4) 系统在柑桔果园分布的基础上,结合地形、土壤、养分等数据,建立了每个果园的三维地貌图、地形图、土壤图等果园的对应数据,从而为果园的生产管理提供了直观的评价更多还原

【Abstract】 Modern agricultural resource information system, which based on the cores of Remote Sense(RS), Geographical Information System (GIS), Global Position System (GPS) technology, is the modern spatial information management system. If the technology above all are aggregated and applied, it can enormously improves not only the initiative of agricultural production, but also makes the great change in the traditional agriculture that infuses the social economy, advanced science and technology, market or other informational resources into the traditional agriculture which is determined by simplex natural resources such as field, water, air, heat and so on.Jiangjing City of Chongqing is a bit prominent region that has a potential condition to citrus industry because of the climatic condition as well as the soil qualification. Unfortunately, there are so many negative factors to restrict badly the high yield of fruit owners and the steady development of agricultural economy as all almost citrus orchards have been build on the hilly countries with a lean soil, lagging elemental equipment, unadvanced management, weak preventive ability to natural calamity, and the greatly irrational layout of citrus industry.Along with the development of citrus industry, it is an inevitable trend to exert the advanced 3S (GIS, GPS, RS) technology, databank technic for researching the layout of citrus industry. To construct the management information system of citrus production not only provides the proof to make a decision of the distribution of citrous production development, but also supplies some basic data of the town planning, resource explor, environmental protection, and river way cleaning. Therefore, the system hold the balance and promote the economical development, standard of living and zoology balance.Based on looking over a great deal of the relative literatures and information, this research paper adopts the field investigation, chamber analysis and applies GIS to build the basic data management of Jiangjing citriculture. At the same time, the research with Arc Object sets the management information system and relevant geographical databank of citriculture in Jiangjing. However, it also precedes a series of systemic and effective investigation according to the atmospheric pollution, average temperature, and field condition. Finally, it has elicited the layout of the citriculture in Jiangjng. In the process to prepare this thesis, there are a set of achievement.Based on the compare of every data model,the Geodatabase was applied to avoid the disadvantage of former data model just as CAD and Coverage.Based on the compare of every development mode, the COM development package—ArcObjects was applied which is included in ArcGIS8.3.The system was developed and更多还原
