为提高森林资源监测工作效率、降低森林资源监测平台建设成本,提出了以网络地图为底图,以林业专题图为现势性较强的参考数据,结合网络地图开发技术、C/S和B/S混合部署模式、AES和MD5混合加密等相关技术和方法,开发森林资源监测平台.该平台以基础年数据为基准,以小班为最小单位,对森林资源数据进行管理,高效、快捷、准确地更新森林资源数据,监测森林资源的数量、质量和林木生长情况.它主要解决如下几个问题:一是采取分布式部署,充分利用硬件资源,提高平台性能;二是采取网络数据加密技术,提高数据的安全性;三是调用网络地图,降低数据建设成本.经过两年的试运行,该平台运行稳定、基本满足用户需求,具有一定的推广性.

This paper presents a system for updating forest compartments and sub-compartments, which is based on QR code technology and forest resources planning and design survey database. The system is divided into the PC-based sub-system and the mobile sub-system. On the PC, the data for the compartments and sub-compartments can be viewed, analyzed, compared and counted, and the changes of forest resources can be informed with the aid of these operations. Based on QR code technology, these operations such as query, comparison and online or offline update can be realized easily in the mobile sub-system. Compared with the traditional survey methods of forestry resources, the proposed system can greatly improve the efficiency of data update and management for compartments & sub-compartments and it can provide an innovative exploration mode for the construction of smart forestry.
