赣南是我国南方地区重要的生态屏障，也是全国木材战略储备生产基地。飞播马尾松林是赣南主要森林资源之一，面积占有林地总面积的21.4%，但其普遍存在林分整体功能较低的问题，针对其难以满足木材生产和生态功能多重需求现状，如何通过调控实现多功能经营是当前亟待解决的科学问题。从系统论结构决定功能观点出发，林分结构对功能有重要影响，且林分空间结构比非空间结构更为重要。本项目以赣南兴国县的飞播马尾松林为研究对象，集成森林经理学、生态学、数学等理论与手段，综合考虑林分结构因子设置样地，通过样地调查与样品测定，明确林分木材生产、涵养水源、固碳和生物多样性功能，揭示林分空间结构特征，探明林分功能与林分空间结构的耦合机理；应用数理统计原理和数据挖掘技术，以多功能经营空间结构为目标，采用多目标规划方法，建立林分多功能经营空间结构模式，提出林分多功能经营调控技术，为赣南飞播马尾松林多功能经营提供科学依据和决策参考。

The region of southern Jiangxi is an important ecological barrier in southern China, which is also the national timber strategic reserve production base. Aerial seeding Pinus massoniana plantation is one of the main forest resources in south Jiangxi covering 21.4% of forestland area, however, this type of stand is generally existing the problem of poor function making it is hard to meet the requirements of timber production and ecological functions at present. Therefore, how to realize multi-function management through regulation is the main issues needed to be solved. From the viewpoint of system theory, stand structure affects its functions significantly. As stand spatial structure is more vital than non-spatial structure, the influences of spatial structure on stand functions will be considered in this research. Aerial seeding Pinus massoniana plantation in Xingguo Country of south Jiangxi is chosen as the research subject. According to stand structure factors, plots are set by theory and methods of forest management, ecology and mathematics. Plots investigation and sample determination will be used to collect data for analyzing the timber production, water conservation, carbon sequestration and biodiversity of the stand, as well as the stand's spatial structure, exposing the coupling mechanism between the stand function and its spatial structure. Mathematical statistics principles and data mining technology as well as multi-objective programming will be used to set up the spatial structure model of stand multi-function management. The stand regulation technology proposed in this research will provide a scientific basis and decision-making reference for the multi-function management of aerial seeding Pinus massoniana plantation in southern Jiangxi.
