【摘要】：2011年9月,國土資源部下發(fā)了《關(guān)于開展2012年度開發(fā)區(qū)土地集約利用評價成果更新工作的通知》(國土資電發(fā)143號),決定開展第二輪開發(fā)區(qū)土地集約利用評價成果更新工作。由于以往評價數(shù)據(jù)采用的靜態(tài)數(shù)據(jù)庫儲存,每次更新都需要重新獨立建庫,缺乏對歷史數(shù)據(jù)的銜接和管理,同時基本上采用的是人機交互編輯圖層更新,更新效率低下,造成人力和物力的浪費。針對目前評價更新工作重復(fù)繁瑣、歷史數(shù)據(jù)缺乏管理、更新效率低下的缺陷,本文開展了開發(fā)區(qū)土地集約利用評價增量更新技術(shù)的研究,利用時空數(shù)據(jù)庫同時儲存歷史數(shù)據(jù)和現(xiàn)勢數(shù)據(jù),采用增量更新技術(shù)實現(xiàn)更新信息的自動判別,并以交互式更新加以補充,從而完成開發(fā)區(qū)土地集約利用評價自動或半自動的更新。本文的具體研究內(nèi)容和成果如下： (1)分析了目前開發(fā)區(qū)土地集約利用評價存在的問題,總結(jié)了幾種評價更新方式的優(yōu)缺點,并對評價更新的內(nèi)容、特征和時空變化關(guān)系進行了詳細分析,選擇時空數(shù)據(jù)庫和增量更新技術(shù)作為評價更新的技術(shù)基礎(chǔ)。 (2)詳細分析了開發(fā)區(qū)土地集約利用評價成果變化的檢測方法,包括增量信息的識別、變化類型的判定和更新操作的執(zhí)行。并在分析比較幾種主流時空數(shù)據(jù)模型的基礎(chǔ)上,結(jié)合開發(fā)區(qū)土地利用評價數(shù)據(jù)的時空特征,選取基態(tài)修正模型和Geodatabase面向?qū)ο髷?shù)據(jù)模型作為增量更新的模型基礎(chǔ),設(shè)計了開發(fā)區(qū)土地集約利用評價時空數(shù)據(jù)模型,并依據(jù)此模型構(gòu)建了時空數(shù)據(jù)庫。 (3)基于本文設(shè)計的開發(fā)區(qū)土地集約利用評價時空數(shù)據(jù)模型,跟蹤記錄評價成果更新過程,對增量更新流程進行了分析與設(shè)計,包括圖形的增量更新、屬性的增量更新和數(shù)據(jù)表的增量更新,并分析交互式更新方法作為補充。同時對主要的時空查詢算法：快照查詢和歷史回溯的算法,進行了詳細的設(shè)計。 (4)在開發(fā)區(qū)土地集約利用評價時空數(shù)據(jù)庫的基礎(chǔ)上,采用增量更新技術(shù),設(shè)計并開發(fā)了開發(fā)區(qū)土地集約利用評價更新系統(tǒng),并將該系統(tǒng)應(yīng)用到江蘇寶應(yīng)經(jīng)濟開發(fā)區(qū)土地集約利用評價更新中,驗證了開發(fā)區(qū)時空數(shù)據(jù)模型的適用性、增量更新方式的優(yōu)越性和查詢算法的正確性,實現(xiàn)了開發(fā)區(qū)土地集約利用評價自動更新與跟蹤管理,基本滿足了開發(fā)區(qū)土地評價更新管理業(yè)務(wù)需求。
[Abstract]:In September 2011, the Ministry of Land and Resources issued the notice on updating the Evaluation results of Land intensive Utilization in the Development Zone in 2012.Because of the static database storage used in the past, each update needs to rebuild the database independently, which lacks the connection and management of the historical data. At the same time, it basically adopts the update of human-computer interactive editing layer, so the updating efficiency is low.Cause waste of human and material resources.In view of the shortcomings of repeated and tedious evaluation and update work, lack of management of historical data and low updating efficiency, this paper has carried out a study on the incremental renewal technology of land intensive utilization evaluation in the development zone.The temporal and spatial databases are used to store both historical and current data, and the incremental updating technique is used to realize the automatic discrimination of updated information, which is supplemented by interactive updating.In order to complete the development zone land use evaluation automatic or semi-automatic update.The specific research contents and results of this paper are as follows:This paper analyzes the problems existing in the evaluation of intensive utilization of land in the development zone, summarizes the advantages and disadvantages of several methods of evaluation and renewal, and analyzes in detail the contents, characteristics and the relationship between the temporal and spatial changes of the evaluation and renewal.The spatiotemporal database and incremental update technology are selected as the technical basis of evaluating update.2) the methods of detecting the change of land intensive utilization evaluation results in the development zone are analyzed in detail, including the identification of incremental information, the determination of change types and the execution of update operations.Based on the analysis and comparison of several mainstream spatio-temporal data models, the ground state modified model and Geodatabase object-oriented data model are selected as the basis of incremental updating model combined with the spatio-temporal characteristics of land use evaluation data in the development zone.The spatiotemporal data model of land intensive utilization evaluation in development zone is designed, and the spatiotemporal database is constructed according to this model.3) based on the spatio-temporal data model of land intensive utilization evaluation in this paper, the updating process of the evaluation results is tracked, and the incremental updating process is analyzed and designed, including the incremental updating of graphics.Attribute incremental update and data table incremental update, and analyze the interactive update method as a supplement.At the same time, the main temporal and spatial query algorithms, snapshot query and history backtracking algorithm, are designed in detail.Based on the spatiotemporal database of land intensive utilization evaluation in the development zone, the paper designs and develops the land intensive utilization evaluation and updating system of the development zone by using incremental updating technology.The system is applied to the evaluation and updating of land intensive utilization in Baoying Economic Development Zone of Jiangsu Province, which verifies the applicability of the spatio-temporal data model of the development zone, the superiority of incremental updating method and the correctness of query algorithm.The automatic updating and tracking management of land intensive utilization evaluation in the development zone is realized, which basically meets the business demand of land evaluation and renewal management in the development zone.
