【摘要】：我國人口多耕地少,耕地后備資源不足,且耕地重中之重的基本農(nóng)田保護(hù)形勢不容樂觀,基于以上國情,堅(jiān)持基本農(nóng)田保護(hù)優(yōu)先,數(shù)據(jù)掌握、數(shù)據(jù)管理與數(shù)據(jù)質(zhì)量并重尤為重要。數(shù)據(jù)質(zhì)量是數(shù)據(jù)的生命,對基本農(nóng)田劃定內(nèi)業(yè)數(shù)據(jù)成果質(zhì)量進(jìn)行檢查控制不僅確保了我國基本農(nóng)田的數(shù)量,而且對其質(zhì)量控制也發(fā)揮了一定的作用,對確保國家糧食安全具有長遠(yuǎn)而重要的意義。 目前,基本農(nóng)田管理中主要存在兩方面問題：一方面,成果資料與實(shí)地相差甚遠(yuǎn),數(shù)據(jù)質(zhì)量不規(guī)范,不符合數(shù)據(jù)庫建設(shè)的要求；另一方面,普通的土地?cái)?shù)據(jù)質(zhì)量檢查軟件待檢查規(guī)則與程序代碼綁定,不能滿足待檢查規(guī)則變動頻繁的要求,軟件重用性差；此外,常用的ArcGIS軟件檢查針對性不強(qiáng),檢查不全面。針對以上問題,本文提出一種基于規(guī)則引擎的基本農(nóng)田劃定內(nèi)業(yè)數(shù)據(jù)質(zhì)量檢查方法。本文著重從以下三方面進(jìn)行研究： (一)深入研究空間數(shù)據(jù)質(zhì)量、基本農(nóng)田劃定內(nèi)業(yè)數(shù)據(jù)質(zhì)量及規(guī)則引擎的研究現(xiàn)狀,分析目前基本農(nóng)田劃定內(nèi)業(yè)數(shù)據(jù)質(zhì)量及普通的檢查軟件中存在的問題,闡述研究基于規(guī)則引擎的基本農(nóng)田劃定內(nèi)業(yè)數(shù)據(jù)質(zhì)量檢查方法的必要性及重要性。 (二)分析比較空間數(shù)據(jù)質(zhì)量檢查方法,采用軟件自動檢查法,基于統(tǒng)一數(shù)據(jù)質(zhì)量評價(jià)模型,提出基于規(guī)則引擎的基本農(nóng)田劃定內(nèi)業(yè)數(shù)據(jù)質(zhì)量檢查方法。分析規(guī)則引擎常用算法的特點(diǎn),采用基于RETE算法的規(guī)則引擎,基于Drools.Net3.0平臺,構(gòu)建基本農(nóng)田劃定內(nèi)業(yè)數(shù)據(jù)質(zhì)量檢查規(guī)則引擎。 (三)利用基于規(guī)則引擎的基本農(nóng)田劃定內(nèi)業(yè)數(shù)據(jù)質(zhì)量檢查方法應(yīng)用于基本農(nóng)田劃定內(nèi)業(yè)數(shù)據(jù)質(zhì)量檢查中,該質(zhì)量檢查方法在浙江省基本農(nóng)田劃定內(nèi)業(yè)數(shù)據(jù)質(zhì)量檢查系統(tǒng)中得以驗(yàn)證,完成了浙江省90個(gè)縣市基本農(nóng)田劃區(qū)定界成果檢查與控制。。 基于規(guī)則引擎的基本農(nóng)田劃定內(nèi)業(yè)數(shù)據(jù)質(zhì)量檢查方法優(yōu)于普通的土地?cái)?shù)據(jù)質(zhì)量檢查方法及ArcGIS軟件檢查法,該方法實(shí)現(xiàn)了業(yè)務(wù)與代碼相分離,解決系統(tǒng)重用困難的同時(shí)全面完成了數(shù)據(jù)質(zhì)量規(guī)范性檢查。此外,提升了檢查效率,滿足檢查規(guī)則變動頻繁的要求,更適用于未來的生產(chǎn)工作中。
[Abstract]:The situation of basic farmland protection is not optimistic. Based on the above national conditions, we insist on the priority of the basic farmland protection, and the data management and data quality are particularly important. Data quality is the life of data, and the quality of the data in the basic farmland is delimited to the basic farmland. Inspection and control not only ensured the quantity of basic farmland in our country, but also played a certain role in its quality control, and had a long and important significance to ensure the national food security.
At present, there are two main problems in the management of basic farmland: on the one hand, the results are far from the field, the quality of the data is not standard and does not meet the requirements of the construction of the database. On the other hand, the common land data quality inspection software should not meet the requirements of the frequent changes of the rules to be checked. The software reusability is poor; in addition, the common ArcGIS software inspection is not pertinent and the inspection is not comprehensive. In view of the above problems, this paper proposes a method for the quality inspection of the internal industry data based on the basic farmland based on the rule engine. This paper focuses on the following three aspects:
(1) in-depth study of the quality of spatial data, the research status of the quality of internal data and the rule engine in the basic farmland, and the analysis of the existing problems in the quality of the internal data and the common inspection software in the basic farmland, and the necessity and importance of the study of the method for the quality inspection of the internal data based on the basic farmland based on the rule engine.
(two) analyzing and comparing the methods of spatial data quality inspection, using the software automatic inspection method and based on the unified data quality evaluation model, this paper puts forward the method for the quality inspection of the internal industry data based on the rule engine, analyzes the characteristics of the rules engine commonly used algorithms, uses the rule engine based on the RETE algorithm, and builds on the Drools.Net3.0 platform. Basic farmland is used to delineate internal data quality inspection rule engine.
(three) the quality inspection method of the internal industry data quality inspection based on the basic farmland based on the rule engine is applied to the quality inspection of the internal industry data in the basic farmland. The quality inspection method has been verified in the internal data quality inspection system of the basic farmland delimited in Zhejiang province and completed the inspection of the demarcation results of the basic farmland in the 90 counties and cities in Zhejiang province. And control..
The method of checking internal data quality of basic farmland based on rule engine is better than the common land data quality inspection method and ArcGIS software inspection method. This method realizes the separation of business and code, solves the difficulty of the system reuse and completes the data quality standard inspection at the same time. In addition, it improves the inspection efficiency and satisfies the inspection. The requirement of frequent change of rules is more suitable for future production work.
