摘要:
 在GIS技术的支持下，以C#编程语言与ArcEngine组件库为开发工具，设计开发了融4种边缘校正方法、6种竞争树判断方法、19种竞争指数计算方法为一体的插件式林木竞争指数计算系统，具备了林木竞争指数的计算和林分竞争分析等功能。结果表明，该计算系统简单易用，计算科学，适用于林木竞争指数的研究和应用，具有推广价值。
Abstract:
 Competition index (CI) is an important indicator of forest spatial structure research and plays a core role in people’s understanding of the dynamics of forest. But many CIs are difficult to calculate and expand due to the complex spatial relationship among trees. In this paper, a GIS based CI calculation system was developed with C# and ArcEngine. The system integrated 4 edge correction methods, 6 competitor identification methods and 19 CI calculation methods in a plug-in way, and contained the capacity of competition index calculation, and stand competition analysis. The results showed that this calculation system was easy to use, accurately to calculate, and was suitable for research and application of competition index. The CI calculation system was worth to popularize.
