【摘要】：我國(guó)的耕地資源存在較為明顯的缺陷,耕地質(zhì)量不高,耕地利用效率低以及后備耕地資源儲(chǔ)量的嚴(yán)重不足等現(xiàn)象,再加上我國(guó)耕地資源的不斷減少,已經(jīng)嚴(yán)重影響了我國(guó)農(nóng)業(yè)經(jīng)濟(jì)的發(fā)展。為提高農(nóng)產(chǎn)品的產(chǎn)量,通過(guò)合理利用有效資源提高農(nóng)產(chǎn)品收益,必須改善我國(guó)耕地資源的利用效率,最大限度的發(fā)揮我國(guó)耕地資源的潛力。對(duì)耕地進(jìn)行高效科學(xué)耕種,就必須了解耕地的土壤信息和質(zhì)量。目前我國(guó)在耕地有效利用方面的研究已經(jīng)取得了很大程度的進(jìn)展,如利用層次分析法和模糊綜合評(píng)價(jià)方法進(jìn)行的耕地地力評(píng)價(jià),以及測(cè)土配方施肥等高效的耕地種植技術(shù),都為改變我國(guó)耕地質(zhì)量提供了合理的技術(shù)支持。本文利用ArcGIS Engine組件技術(shù)和ArcSDE的存儲(chǔ)技術(shù),建立耕地資源信息管理系統(tǒng)。通過(guò)對(duì)組件式系統(tǒng)開(kāi)發(fā)開(kāi)發(fā)的原理和特點(diǎn)、ArcGIS Engine二次開(kāi)發(fā)的優(yōu)勢(shì)及特點(diǎn)以及ArcSDE空間數(shù)據(jù)庫(kù)引擎的優(yōu)點(diǎn)等進(jìn)行闡述,討論了系統(tǒng)開(kāi)發(fā)的基本原理。對(duì)耕地資源信息的空間信息和屬性信息進(jìn)行統(tǒng)一化和規(guī)范化處理,利用ArcSDE存入系統(tǒng)的底層數(shù)據(jù)庫(kù)。通過(guò)ArcGIS Engine進(jìn)行耕地資源信息管理系統(tǒng)的構(gòu)建,系統(tǒng)通過(guò)空間查詢(xún)子系統(tǒng),屬性查詢(xún)子系統(tǒng)、耕地地力評(píng)價(jià)查詢(xún)子系統(tǒng)和其他輔助子系統(tǒng)組成耕地資源信息管理系統(tǒng)。系統(tǒng)針對(duì)非相關(guān)專(zhuān)業(yè)的用戶(hù)進(jìn)行開(kāi)發(fā),在這種情況下,系統(tǒng)界面設(shè)計(jì)需簡(jiǎn)潔大方,用戶(hù)通過(guò)簡(jiǎn)潔明了的空間查詢(xún)、屬性查詢(xún)以及耕地地力等級(jí)信息的查詢(xún),對(duì)相關(guān)耕地的地力評(píng)價(jià)信息獲得了解,為用戶(hù)在耕地的科學(xué)種植方面提供參考依據(jù),為進(jìn)一步了解科學(xué)種植奠定了基礎(chǔ)。
[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.
