森林经营决策支持系统的设计与实现及在采伐中的应用

Design and actualization of forest management decision support system and its applications in forest harvesting

我国传统的森林经营方式比较落后,数字化水平不高,决策过程比较盲目。在地理信息系统平台中集成森林动态模型,建立森林经营决策支持系统,可以充分发挥地理信息系统的可视化、空间分析以及模型模拟预测功能,加强处理森林在较大时空尺度上的动态变化的能力。本文设计并实现了森林生长率模型、景观采伐模型和矩阵模型,开发了森林经营决策支持系统,回答森林采伐经营中"采多少,采哪里,怎么采"的三个主要问题,在长白山区的露水河林业局和三岔子林业局进行应用,为提高我国森林可持续经营管理的数字化水平提供了技术支持。

The traditional forest management modes in China are rather lagged behind.Their digitalization level is relatively low,and their decision-making processes are somewhat subjective,without using explicit data and information.To integrate forest dynamics models into geographic information system to develop forest management decision support system could fully bring the visualization and spatial analysis technologies as well as the model simulation and prediction functions into play,and strengthen the capability of dealing with forest dynamic changes at large spatiotemporal scales.This paper designed and actualized forest growth model,landscape harvesting model,and matrix model,and developed a sustainable forest management decision support system to answer the questions ＂what,where,and how＂ in forest harvesting practices.The decision support system was applied in Lushuihe and Sanchazi forestry bureaus of Changbai Mountain area,which could provide broader implication for the digital technique applications in forest management in China.
