基于WebGIS技术的吉林省国土资源信息系统

在WebGIS支持下，通过系统设计、系统分析和系统实现，构建吉林省国土资源网络信息系统。系统设计采用流行的三层结构模型，客户端与服务器的通讯和联接使用TCP／IP和HTTP通过Internet／Intranet实现。服务器端应用程序与后台数据库的通讯通过JDBC技术实现。系统主要由8个子系统构成，即数字矿产、数字旅游、数字气象、数字生态、数字国土、数字水资源、数字植被和地壳稳定性子系统。系统的建立实现了吉林省国土资源信息共享、科学管理、合理开发和有效利用。

WebGIS-Based Territorial Resource Information System of Jilin Province

On the base of Web GIS, Jilin Land and Resources Web Information System can be established through three steps: system design, system analysis and system realization. In the step of system designing, three-layer model is applied, and the communication and connection between the client and the server can be realized by using TCP/HTTP through Internet/Intranet. The communication between the applied program of the server and the database of the background can become true with JDBC technology. The whole system is composed of eight subsystems. They are digital minerals subsystem, digital touring subsystem, digital weather forecast subsystem, digital zoology subsystem, digital land subsystem, digital water resource subsystem, digital vegetation subsystem and stability of the earth's crust subsystem. The establishment of this system can realize information sharing, scientific management, rational exploitation and effective utilization of Jilin land resource information.
