摘　　要： 基于MO和MATLAB平台,采用地理信息二次开发技术,建立了帽儿山林场老山实验站森林资源蓄积量评估和预测的地理信息系统,该系统整合在GIS平台上整合BP人工神经网络模型,模拟计算老山实验站森林蓄积量。系统具有前后台数据传输功能,并实现了基于GIS的智能分析计算,为森林资源蓄积量的模拟和预测提供了数字化、可视化、智能化方法。 The platforms of MO and MATLAB was effectively combined, and the evaluation of forest resource reserve as well as the GIS for prediction in Lao Shan Experimental Base was also established by the second development. The historical data is learned and the forest resource reserve of Lao Shan Experimental base is predicted and calculated by the adopting Artificial Neural Network of BP on the platform of GIS in the system. The system possesses the transmission function for database between the platforms and the analysis of GIS intellectual determination is realized. The study also provides the digitalized, visualized and intellectualized research system and method for the simulation and prediction for regional variations.
