从系统论观点认识和思考现代林业

森林、湿地和荒漠生态系统组成了陆地生命支撑体系的主体,构成现代林业的根基。三大生态系统构成了一个开放、整体、动态和远离平衡态等的生态巨系统,物质、能量循环和信息在三大系统与环境之间持续交换,各子系统之间彼此联系,相互影响。随着人类活动加深,经济社会与生态系统构成了一个关系更为紧密的人类-经济-社会复合生态系统。系统论、耗散结构理论和协同论为协调复合生态系统发展,建设生态文明和发展现代林业提供了建设思路。

Thoughts of mordern forestry from viewpoints of system theory

Forests, wetlands and desert ecosystems compose a main body of the land life support system and are consisted of the foundation of modern forestry. The three ecosystems constitutes an open , overall, far from equilibrium dynamics eco--giant system, where material, energy and information circulation systems exchange with the environment, and the subsystems exchange with each other, influence each oth- er. With the deepening of human activities, economic and social and ecological systems form a closer relationship between human beings -- e- conomy -- society complex ecosystems. System theory, dissipative structure theory and coordination provide some suggestions to the complex ecosystem development, the construction of ecological civilization and the development of modern forestry.
