This project integrates professional knowledge and decision-making technologies required for the entire production and management process of fast-growing and high-yield plantations using information technology, aiming to modernize forestry production management through informatization. It researches information service mechanisms targeting forestry enterprises and farmers, as well as related knowledge management and knowledge representation technologies. Taking fast-growing tree species such as poplar in northern China and eucalyptus in southern China as research objects, it develops remote consultation service systems for fast-growing and high-yield plantation cultivation techniques and intelligent decision support systems for the production (cultivation) and management processes of fast-growing and high-yield plantations. The project aims to transform the backward and extensive management modes, conserve resources, improve land productivity, and alleviate the contradiction between timber supply and demand in China, while increasing the economic income of forestry enterprises, forest farms and farmers. The project researches information service mechanisms targeting farmers and related knowledge management and knowledge representation technologies, with fast-growing tree species as the main research objects. It constructs knowledge bases for fast-growing and high-yield plantation cultivation techniques and pest and disease diagnosis and treatment with dynamic update functions. It studies the knowledge composition, acquisition technologies and decision-making inference processes of experts in fast-growing and high-yield plantation cultivation and management. It integrates growth yield and management decision-making models and stand management dynamic decision-making technologies, and develops four systems respectively for different regions, tree species and management modes: forest cultivation expert decision support system, remote consultation system for fast-growing and high-yield plantation cultivation techniques in Northeast China, eucalyptus fast-growing and high-yield plantation expert decision support system, and poplar fast-growing and high-yield plantation production and management intelligent decision support system. These systems provide full-range expert decision support and technical guidance for various operation stages such as afforestation land diagnosis, afforestation tree species and forest cultivation mode decision-making during the forest cultivation process, via the Internet, for grassroots forestry bureaus, forestry workstations, forest farms, nurseries and farmers in Guangxi, Beijing, Hebei, Shandong and Northeast China. They also provide specialized expert consultation on fast-growing and high-yield plantation production and cultivation techniques, and calculate and evaluate their economic benefits. In addition, they provide improved forest tree seed information and cultivation techniques for main afforestation tree species, expert knowledge for forest pest and disease diagnosis and treatment, training courses for ecological management personnel suitable for farmers' learning, introduction to forest cultivation techniques, and online teaching materials for poplar fast-growing plantation cultivation techniques. Through the demonstration and promotion of these systems, the original management modes can be improved and forestry management levels can be enhanced, with obvious economic income benefits for forestry enterprises, forest farms and farmers. The project's construction results have been promoted and applied over an area of 857,700 mu in Guangxi. By applying the eucalyptus cultivation and management decision support system, informatized management and comprehensive management decisions such as improved variety selection, site-specific tree planting, density management and harvest control have been realized. The average annual growth of eucalyptus stands in demonstration forest farms can be increased by 2.0-4.0 m³/hm²/year. Converted to stock volume, the stock volume of 6-year-old eucalyptus in the demonstration promotion area can be increased by 12-24 m³/hm². Based on the stock volume increase of 12 m³/hm², 70% timber recovery rate, and the eucalyptus price of 600 yuan per cubic meter, the annual income increase per mu of eucalyptus can reach 56 yuan. For 857,700 mu of eucalyptus, the cumulative income increase over one rotation period (6 years) can reach 288,187,200 yuan.
