    摘要:

    野外數(shù)據(jù)采集具有靈活性強(qiáng)、采集內(nèi)容多樣、準(zhǔn)確度高等優(yōu)勢,已成為補(bǔ)充完善農(nóng)業(yè)數(shù)據(jù)的主要手段之一。作物種植環(huán)境數(shù)據(jù)采集工作存在指標(biāo)多并隨調(diào)查區(qū)域、作物類型與作物生育期不同而發(fā)生變化等特點(diǎn),采用傳統(tǒng)方式設(shè)計(jì)調(diào)查界面與錄入模式難以滿足數(shù)據(jù)采集的普適性需求。為此,在分析作物種植環(huán)境數(shù)據(jù)采集工作實(shí)際需求的基礎(chǔ)上設(shè)計(jì)并實(shí)現(xiàn)了作物種植環(huán)境數(shù)據(jù)采集系統(tǒng)(CPEDCS)原型。一方面,系統(tǒng)針對(duì)作物種植環(huán)境指標(biāo)的不確定性特征提出基于結(jié)構(gòu)表的用戶可定制種植環(huán)境數(shù)據(jù)錄入模式,支持用戶自定義錄入界面;另一方面,系統(tǒng)集成移動(dòng)GIS為野外采集工作提供空間信息支持,并可以動(dòng)態(tài)適應(yīng)空間數(shù)據(jù)類型、數(shù)量、范圍的變化。研究的數(shù)據(jù)組織模型在陜西省楊凌區(qū)小麥種植環(huán)境野外調(diào)查的實(shí)際應(yīng)用中,表現(xiàn)出良好的實(shí)用性與穩(wěn)定性,一定程度上提高了采集工作效率,減少了數(shù)據(jù)錄入出錯(cuò)率并能為調(diào)查人員提供空間信息輔助功能。

    Abstract:

    Field data collection, comparing with other data acquisition methods such as remote sensing or wireless sensor network, has advantages of high flexibility, high accuracy and gradually becoming one of the main methods for complementing agricultural data.We analyzed the actual demands of crop planting environment data collection work, and on that basis, presented an Android based crop planting environment data collecting system prototype (CPEDCS). Firstly, in consideration of uncertainty characteristics of crop planting environment indicators, we designed a customizable data input mode based on structural data table, which supports users to set indicators by editing XML file, defines visibility and arrangement of indicators, and configures default value of each indicator; secondly, mobile GIS module was integrated in CPEDCS client to provide spatial information, and the module can automatically adapt to variation of data type, file quantity and spatial range; thirdly, we realized efficient image data management and application by image data acquisition, compression, coding and transmission, and users can query image data in different sample points realtime through browser. At last, we applied our system on crop planting environment data collection work in Yangling District, Shanxi Province in April, 2013 and April, 2014. The experimental results show that the CPEDCS has high practicability and stability, and to some extent could increase data collecting efficiency, reduce error rate on data input, and provide spatial information for investigators.
