【摘要】 四川林业资源丰富，近年来地震情况多发，使林业经营管理与决策分析等多方面工作都面临着严峻的考验。本研究根据四川地震后受灾森林的破损情况，针对受灾前后的森林资源数据及业务数据等资料进行整合分析，结合森林恢复工程规划实施流程，对森林恢复辅助决策的业务特征进行分析，总结出震后森林恢复辅助决策体系架构；分析森林恢复可视化的构成要素间的相互关系，研究构建森林恢复模拟场景的关键技术，并以信息服务为支撑，实现四川震后森林恢复可视化信息服务平台的建立。1）通过对四川震后森林恢复信息获取、辅助决策体系、森林恢复可视化三方面内涵的分析研究，论述了三者之间的相关性。根据对震后森林恢复的业务层次的分析，梳理整合震后森林恢复辅助决策的流程特点。根据震后森林恢复的空间尺度与时间尺度特征，分析建立了震后森林恢复可视化的层次结构。通过可视化与震后森林恢复辅助决策业务流的交互作用关系的建立，支撑决策者进行优化辅助决策。针对震后森林恢复可视化服务层次与业务、管理、功能和技术四个维度结合分析，构建了以震后森林调查数据为中心，多维度交互作用的震后森林恢复可视化决策架构模型。从总体上明确可视化信息服务的意义。2）分析震后四川森林资源受灾情况、地形数据、造林规划等数据的层次性、相关性，从各级数据获取来源的特征进行综合分析，以确定开展震后森林恢复辅助决策的数据支撑，也为构建可视化服务平台建立数据基础。3）研究震后森林恢复辅助决策信息服务体系层次，依据宏观到微观的层次递进原则，根据震后森林恢复管理规划的业务流程特点，提出了造林恢复规划辅助决策信息服务、造林作业设计辅助决策信息服务和参与式造林辅助决策信息服务的技术体系，提高震后森林恢复决策的高效性和科学性。4）通过对震后森林恢复可视化模拟场景的构成要素之间的关联性、表达性、交互性等的分析，确定了可视化场景中空间可视化描述图层与主要要素关系；分析研究了震后森林恢复可视化在空间尺度与时间尺度上的特性，利用树木竞争模型、生长模型和枯死模型，研究树木到林分构成可视化场景变化规律；研究多尺度环境下高效的、动态的震后森林恢复可视化信息构建的关键技术，实现森林恢复场景的可视化构建。5）建立了四川震后森林恢复可视化信息服务平台，为地震灾后林业资源综合管理规划决策服务。集成了多级树木的模型，从动态、直观的角度体现了震后造林恢复工程的业务流程，同时通过二三维联动综合可视化给决策者提供了有效的支撑。更多还原

【Abstract】 In Sichuan, the forestry resources is rich. In recent years，the earthquake disaster, have putforward the severe problem to forestry management and decision analysis and many otheraspects. According to the damage situation of Sichuan after the earthquake disaster of forest,the article analyed the forest resources data and business data of before and after theearthquake. Combined with forest restoration project planning, it analyzed the features ofbusiness process decision on forest restoration.And concluded the structure the auxiliarydecision system of forest restoration after the earthquake. The article analyed the relationshipwith the elements for forest restoration visualization, studied the technology to build forestrestoration simulation, and with the information service,the information service platform isestablished for forest restoration visualization.1）The forest-restoration post-earthquake in Sichuan, assistant decision systems,and threeaspects of forest-restoration visualization are the important contents in this article.According toanalysis for the post-earthquake recovery operations levels,this paper sort out the features ofassistant decision of the forest-restoration after Sichuan earthquake.According to the spatialand time scale features of forest-restoration, this paper analyzes and buildsthevisualhierarchyofforest-restoration after the earthquake.Through interaction relations of visualization andassistant decision of forest-restoration after the earthquake, decision makers are supportedtomake the optimal decision.For the four dimensions analysics of visualization service levels,business, management, functional and technical in forest-restoration after the earthquake,thevisualization decisionmodelis builded.This model is based on the forest survey data,andeffected with the visualization service levels, business, management, functional and technical.2）Analyzed hierarchy and relevance about the data such as forestland resources data,terrain data, the afforestation plan data which from the earthquake disaster situation inSichuan,comprehensive analyzed the characteristics of the various data to carry out the data to support the forest-restoration assistant decision after the earthquake,and also established a database for visualization service platform.3）Studied the information services architecture about forest-restoration policy-decisionafter the earthquake,following the progressive principle which from macroscopic tomicrocosmic level, according to business process characteristics about post-earthquakerecovery management forestplanning, put forward technology system which contain theafforestation recovery planning assistant decision-making information service,forestsmall-class job design aided decision-making information service and participatosrydecision-making information service, improved efficient and scientific in forest-restorationdecision-making after the quake.4）Analyzed the correlation, expressive, interactivity about the elements which consists ofpost-earthquake forest-restoration visual simulation scenarios，determined the relationshipbetween the space visualization describe layer in visual scene and main factors;analyzedcharacteristic about the earthquake forestland restore visual features on spatial scale and timescale,studied the trees to visualize changes of scene stands constituted with using treescompetition model, growth model and the dead model;studied the key technologies aboutefficient and dynamic forestland restoration visual information after the earthquake undermulti-scale environments,achieved and builded visualization in forestland recovery scenarios.5）Visualization information service platform is established for the sichuan earthquakeforest-restoration,provided services for post-earthquake forest resources comprehensivemanagement planning decision-making. Integrated multi-level tree models,reflected theafforestation recovery after the earthquake engineering business processes in dynamic andintuitive,provided effective support for decision-maker through two and three-dimensionallinkage integrated visualization.更多还原
