森林资源是极其重要的自然资源。利用3S(GIS、RS、GPS)技术、数据库技术,以及网络技术建立森林防火信息系统对减少森林火灾损失具有重要意义。本文以四川省遂宁市为例,对该市森林防火信息系统的结构和功能、系统的数据库进行了设计、建设。该系统数据库的数据主要有1∶1万地形图,1∶1万森林资源二类调查数据,气象站点数据,扑火力量分布数据,了望站点分布数据,扑火物资储备数据,林业管理机构分布数据,以村或乡镇为单位的人口、经济统计数据及遥感影像数据库。该系统的主要功能包括数据的处理和管理,森林火险等级评价,森林火灾监测,林火趋势模拟和预测,最佳扑火路径分析,防火扑火预案制定,防火扑火决策,灾害损失评估,灾后重建辅助决策,相关图、表和报告制作等功能。在系统的搭建过程中,采用Microsoft Visual Studio 2005作为开发平台,利用Ar-cEngine组件对象模型进行软件系统的开发,采用SQL Server 2005数据库管理系统和ArcSDE 9.2空间数据库引擎来实现该系统的数据管理。该系统的建立对该市森林防火和森林资源管理等均具有重要意义。
Forest resources are extremely important natural resources. The use of 3S (GIS, RS, GPS) technology, database technology and network technology to establish a forest fire information system is of great importance to reduce forest fire losses. In this paper, Suining City, Sichuan Province as an example, the city’s forest fire information system structure and function of the database system for the design and construction. The data of the system database mainly includes 1: 10000 topographic maps, 1: 10,000 forest resources survey data, meteorological site data, firepower distribution data, lookout site distribution data, firefighting materials reserve data, forestry management agencies Distribution data, population by village or township, economic statistics data and remote sensing image database. The main functions of the system include data processing and management, forest fire rating, forest fire monitoring, forest fire trend simulation and forecasting, best firefighting path analysis, firefighting plan, firefighting decision, disaster loss assessment, Post-disaster reconstruction aided decision-making, related maps, tables and reports and other functions. In the process of building the system, Microsoft Visual Studio 2005 was used as the development platform to develop the software system using Ar-cEngine component object model. The data management of the system was realized by using SQL Server 2005 database management system and ArcSDE 9.2 spatial database engine. The establishment of the system is of great significance to the city’s forest fire prevention and forest resource management.
