基于ArcGIS的森林资源动态监测工具开发——以浙江省龙泉市为例

New ArcGIS Tools Developed for Dynamic Forest Resources Monitoring————A Case Study of Longquan City

森林资源数据管理是林业部门工作的核心内容,开展森林资源动态监测不但可以让林业工作者及时了解本地区的森林资源状况,而且能够为科学合理地制定林业发展方针政策提供准确的数据支持。该研究以ArcGIS软件为平台,以浙江省龙泉市森林资源年度监测为例,采用C#及Python计算机程序语言,开发了一套森林资源动态监测工具,主要功能包括数据库属性字段管理、主要林分调查因子计算及更新、属性因子代码转换、小班编号、属性因子复制、逻辑检查。结果表明:基于GIS软件平台的扩展工具开发,可以为林业部门开展森林资源动态监测提供有效的解决方案,在提高林业工作者生产效率的同时,也能够确保更新数据的质量。

Forest resources data management is the key responsibility for the forestry departments, the forest resources dynamic monitoring can not only help forest workers to understand the status of forest resources in the region in time, but also provide accurate data supporting for making scientific and reasonable policies of forestry developing. We took the annual monitoring of forest resources in Longquan City of Zhejiang Province as an example, the tools have been developed for forest resources dynamic monitoring based on ArcGIS software platform, these tools have been programmed using C# and Python including these functions, database attribute fields management, the calculation and updating of major stand factors, codes conversion, subcompartment numbering, attribute factors coping, logical checking. The results indicated that it would be an effective solution for carrying out forest resources dynamic monitoring of forestry departments by customizing tools based on GIS software platform. As a result, the productivity of the forestry workers and the quality of updated data could be improved.
