【摘要】 福建林区是我国南方的重要林区，在森林资源林政管理方面，因情况复杂、手段落后以及人为干扰，许多管理措施和办法难以得到有效的执行。长期以来，超限额采伐、无证采伐、超证采伐、无证运输、伪造运输证、买卖码单等违法现象屡禁不止。事实已经证明原有的依靠人工的管理手段已经严重制约了森林资源林政管理水平的进一步提高。景林、钟一文等研制的林木采伐审批计算机管理系统、基于IC卡技术的木材运输审批管理系统、林业规费票据管理系统和林业站计算机管理系统，较好地解决了福建林区森林资源林政管理工作中采伐证、运输证的审批管理无软件可用的问题，促进了采伐证、运输证审批管理的科学化、规范化，为进一步实现计算机林政管理打下了良好的基础。 在总结上述有关林政管理的计算机系统的基础上，笔者致力于构建功能更为完善且适用于福建林区的计算机林政管理系统。根据林业主管部门的实际情况，对系统的网络设计、功能与流程设计以及数据库设计都作了较为深入细致的讨论。为了实现系统的实时通信，以便于及时掌握各种数据和各项业务的办理情况，适应多点办证，提高系统的办证效率，构建了系统的网络结构并给出了数据通信方式，同时也阐述了在现有Internet基础上构建VPN虚拟网的原则和方法。另外，在综合研究了采伐审批管理、伐区管理、木材运输管理、林业规费管理、加工企业管理等功能模块及其流程的基础上，着重论述了林业行政处罚管理模块，并首次建立了林业行政处罚管理的系统流程图。数据库在计算机林政管理系统中具有非常重要的地位，林政管理工作中有大量的数据要统计、查询和处理，为此，还论述了系统的数据库设计，并给出了具体的数据表的实例。此外，考虑到界面对于应用系统的重要性以及数据源设置、服务器设置、消息的发送与接收对于实现系统的关键性作用，给出了系统的主要代码和界面设计原则及其实例。最后，对系统作了总结和讨论，指出了系统继续完善的方向。更多还原

【Abstract】 Fujian forest area is an important forest area in the South of China. Because of the complex situation, out-dated means and man-made interference, many measures can’t be performed effectively. In a long term, all kinds of illicitness occurred frequently, which include cutting outdone the quota, cutting without licenses, cutting outdone the permissible quantity, transportation without certificates, faking transportation certificates and illegal exchange on forestry bills. The fact proves that the man-made means has heavily hindered improving the level of forest administration. "Computer management system for examining forest cutting", "computer management system for examining wood transportation based on 1C card technology", "computer management system used for collection of forestry fund and fee", and "computer management system used in forestry work station", which are developed by Jing Lin and Zhong Yi-wen, have provided a series of software for dealing with cutting licenses and transportation certificates, promoted scientificity and normalization in examining cutting licenses and transportation certificates, and based computer management system for forest administration.Based on the former computer management systems relating to forest administration, this paper is dedicated to develop a computer management system for forest administration with perfect functions which are applicable to Fujian forest area. According with the practice of forest administration, this paper elaborates vividly the design of network, function, flow process diagram and database with a lot of pictures. Depending on VPN, the computer management system can realize real-time communication, so that users can master timely all kinds of data and handle various licenses and certificates, the administration efficiency will be enhanced accordingly. For this reason, this paper firstly introduces the design of network structure, the mode of data communication and the design principles of VPN based on Internet. After describing examining forest cutting module, cutting area administration module, timber transportation administration module, forestry fund and feecollection module, process enterprise administration module and their flow process diagrams, this paper elaborates forestry penalty administration module and generates its flow process diagram first time. In forest administration operation, users must handle much data. In view of the importance of database, this paper introduces the design of database and gives some samples of data structure tables. Location set of data source and serve computer is the key in the course of development, the technology of transmitting and receiving message is vital in the operation of system, too. Thinking of these factors, this paper gives their codes. At the same time, the interfaces and their operation are very important for an applying system. Then this paper gives design principles of interfaces and some examples. Finally, this paper summarizes the content and discusses some insufficiencies of the system and gives next target of research.更多还原
