【摘要】：土壤分類(lèi)是土壤科學(xué)水平的標(biāo)志,以診斷層土壤特性與成土關(guān)系為基礎(chǔ)的譜系式的土壤系統(tǒng)分類(lèi)日益取得廣泛應(yīng)用,并發(fā)展成為國(guó)內(nèi)外土壤信息交流的媒介。土系信息系統(tǒng)是地理信息系統(tǒng)在土壤科學(xué)中應(yīng)用分支之一,其以土壤系統(tǒng)分類(lèi)信息為數(shù)據(jù)對(duì)象,以GIS技術(shù)和數(shù)據(jù)庫(kù)為技術(shù)支撐,是一套具有數(shù)據(jù)管理、空間分析、信息服務(wù)的人機(jī)交互可視化技術(shù)系統(tǒng)。其輔助土壤工作者深入挖掘土壤信息,提高土壤測(cè)圖、資源監(jiān)測(cè)與評(píng)價(jià)、養(yǎng)分管理的能力,對(duì)促進(jìn)土壤資源信息互通共享具有重大意義。本文以“我國(guó)土系調(diào)查與《中國(guó)土系志(中西部卷)》編制”項(xiàng)目為契機(jī),在陜西省范圍內(nèi)展開(kāi)野外調(diào)查,挖掘176個(gè)土系剖面,結(jié)合室內(nèi)土壤理化性質(zhì)分析結(jié)果,按照中國(guó)土壤系統(tǒng)分類(lèi)標(biāo)準(zhǔn)完成對(duì)土壤類(lèi)型自上而下層級(jí)重構(gòu);并以此為數(shù)據(jù)源,建立陜西省土系信息查詢(xún)系統(tǒng),研究成果如下。(1)土壤分類(lèi)甄別:按照土綱-亞綱-土類(lèi)-亞類(lèi)-土族-土系這樣譜系式結(jié)構(gòu)規(guī)范整編了土壤分類(lèi)信息,全省土壤歸屬7個(gè)土綱、14個(gè)亞綱、42個(gè)土類(lèi)、67個(gè)亞類(lèi)、176個(gè)土系,土系命名與劃分符合規(guī)范標(biāo)準(zhǔn)。(2)構(gòu)建土系信息數(shù)據(jù)庫(kù):結(jié)合土系剖面空間分布,規(guī)范化處理了陜西省土壤圖、DEM、水系圖和行政區(qū)劃圖等空間數(shù)據(jù),以此為底圖運(yùn)用Geodatabase建立土系空間數(shù)據(jù)庫(kù)。通過(guò)對(duì)土系環(huán)境背景信息、土系命名信息、土系化學(xué)性質(zhì)信息、土系物理性質(zhì)信息和土系景觀照片等多種維度信息的標(biāo)準(zhǔn)化與編碼處理,建立起其與土系剖面之間的邏輯關(guān)系,依據(jù)數(shù)據(jù)庫(kù)設(shè)計(jì)原則構(gòu)建了基于SQLServer 2012的關(guān)系型土系屬性數(shù)據(jù)庫(kù)。后應(yīng)用土系編號(hào)實(shí)現(xiàn)空間數(shù)據(jù)庫(kù)與屬性數(shù)據(jù)庫(kù)連接。(3)土系信息查詢(xún)系統(tǒng)開(kāi)發(fā):面向用戶(hù)需求以及科學(xué)管理需要,以土系信息數(shù)據(jù)庫(kù)為基礎(chǔ),結(jié)合系統(tǒng)設(shè)計(jì)原則,完成了陜西省土系信息查詢(xún)系統(tǒng)的結(jié)構(gòu)與功能設(shè)計(jì)。并運(yùn)用C#計(jì)算機(jī)語(yǔ)言與ArcGIS Engine組件式開(kāi)發(fā)方式,在VisualStudio 2012的環(huán)境下實(shí)施系統(tǒng)開(kāi)發(fā),經(jīng)系統(tǒng)調(diào)試、優(yōu)化初步實(shí)現(xiàn)陜西省土系信息查詢(xún)系統(tǒng)的研建,該系統(tǒng)具備空間查詢(xún)、屬性查詢(xún)、數(shù)據(jù)管理、數(shù)據(jù)導(dǎo)出等功能,為土系空間數(shù)據(jù)、屬性數(shù)據(jù)科學(xué)管理與信息服務(wù)提供有力的實(shí)踐支持。
[Abstract]:Soil classification is a symbol of soil science level. The classification of soil system based on the relationship between soil characteristics and soil formation has been widely used and developed into a medium of soil information exchange at home and abroad. Soil system information system is one of the branches of application of geographic information system in soil science, and it is divided into soil system Class information is a data object, which is supported by GIS technology and database technology. It is a set of human-computer interaction visualization technology system with data management, spatial analysis and information service. It assists soil workers to dig soil information deeply, improve soil mapping, resource monitoring and evaluation, nutrient management ability, and promote soil resource information mutual information. Through the "China soil survey and the Chinese soil Department (central and Western volume)" project as an opportunity, this article unfolds the field survey in Shaanxi Province, excavate 176 soil sections, and combine the results of the soil physical and chemical analysis, and complete the top-down layer of soil type according to the Chinese soil system classification standard. The soil classification information inquiry system of Shaanxi province is established as the data source. (1) classification of soil classification: the soil classification information is compiled according to the genealogical subclass soil subclass soil family and soil family system, and the soil belongs to 7 soil classes, 14 subclasses, 42 soil classes, 67 subclasses, 176 soil systems and soil systems. The naming and division conforms to the standard standard. (2) building soil information database: combining the spatial distribution of soil profile, the soil map, DEM, water system map and administrative division map of Shaanxi province are normalized to establish the spatial database of soil system based on Geodatabase. The normalization and coding of various dimensional information such as chemical property information, soil physical property information and soil system landscape photos are established, and the logical relation between them and soil profile is established. Based on the database design principle, a relational data base of relational soil system based on SQLServer 2012 is constructed. Attribute database connection. (3) development of soil system information query system: facing user needs and scientific management needs, based on soil system information database and combining system design principles, the structure and function design of Shaanxi soil system information query system are completed. The C# computer language and ArcGIS Engine component development mode are used in VisualS Under the environment of tudio 2012, the system is developed, and through system debugging, the system of Shaanxi soil information query is optimized. The system has the functions of spatial query, attribute query, data management, data export and so on. It provides strong practical support for soil spatial data, attribute data scientific management and information service.
