About the Program

本项目针对越南森林可燃物载量监测和经营成本高，森林可燃物载量监测装备、技术和方法亟需更新，森林可燃物载量快速精准监测和评估能力提高等问题，向越南林业大学提供森林可燃物载量数字化监测与智能化经营技术（包括：基于地面测树装备的立木可燃物载量建模数据采集方法和建模技术、森林可燃物载量智能化经营管理技术），以及相应技术指导。乙方向甲方提供该套技术推广试验基地，以实际行动积极推动中国与越南农林业交流与合作。

This project addresses issues such as the high cost of monitoring forest fuel load and management in Vietnam, the urgent need to update monitoring equipment, technologies, and methods for forest fuel load, and the improvement of capabilities for rapid and accurate monitoring and assessment of forest fuel load. It provides the Vietnam University of Forestry with digital monitoring and intelligent management technologies for forest fuel load (including: data collection methods and modeling techniques for standing tree fuel load based on ground-based tree measurement equipment, as well as intelligent management technologies for forest fuel load), along with corresponding technical guidance. Party B provides Party A with a pilot base for the promotion of this set of technologies, actively promoting agricultural and forestry exchanges and cooperation between China and Vietnam through practical actions.

In collaboration with Vietnam University of Forestry, a comprehensive monitoring and intelligent management experimental base for forest fuel load was established to demonstrate data collection methods and modeling techniques for standing tree fuel load using ground-based digital tree measurement equipment. Within the experimental base, an electronic compass was used to measure the perimeter of sample plots to define the spatial scope (each covering 1 mu, i.e., 25.82 × 25.82 meters). Within these plots, tree factors such as diameter at breast height (DBH), tree height, and relative position were measured. An electronic caliper was employed to measure the DBH of sample trees, while telescopic height poles and wearable height-measuring caps were used to determine tree height and crown width. The collected data were wirelessly transmitted via the "Tree Data Collection and Management Platform App" to mobile devices for building mutual conversion models between stand volume and fuel load, enabling the calculation of forest fuel load at both individual tree and plot scales.Demonstrations of structured and intelligent management technologies for forest fuel load were also conducted. Methods such as the Q-value were used to analyze the diameter and height structures under different stand basal area conditions, while O-ring and uniform angle index methods were applied to study spatial patterns of trees under specific site conditions. Spatial species segregation was calculated based on mingling and diversity indices, and competition intensity among trees was assessed using methods such as those by Hegyi, Bitterlich, and Gadow. Based on these analyses, the "Portable Digital Tree Measurement Data Management System V1.0" was used to compute and analyze the structured management indicators collected by the app, directly guiding managers in identifying trees requiring thinning or harvesting, thereby achieving precision management of forest fuels. A total of 13 patents were applied for, including 4 invention patents and 9 utility model patents, along with 11 software copyrights. One monograph was published, and 30 academic papers were issued.
