试论工业人工林生态学特征

本文对工业人工林生态系统的生态学属性、种群结构、物质循环、能量利用等方面的生态学特征进行了初步的分析,认为工业人工林生态系统具有种群少、结构简单、系统脆弱、经营过程中养分的输出大于输入、人工能源的投入比重大等与其他林种所不同的特征,在发展工业人工林的同时,必须全面、综合、正确地把握其性质特征,运用工程设计的方法与手段,以生态经营区为基本单位面积,对工业人工林进行合理的时空布局,协调好专门化目标生产和生态系统稳定性的关系。

A Discussion on the Ecological Characteristics of Industrial Artificial Forest

This article carries out the preliminary analyses of ecological char-acteristics in many respects, such as ecological attribute, population structure,matter cycle and energy utilization of the ecosystem of industrial artificial forestand considers that the ecosystem of industrial artificial forest possesses the fol-lowing characteristics: few populations, simple structures, fragile system, theoutput bigger than the input of nutrients in the course of management, and thelarge proportion of artificial energy input.These characteristics are differentfrom those of other forest kinds. At the same time of developing industrial for-est, its qualities and characteristics should be grasped overall, comprehensivelyand correctly. The rational.space-time distribution for industrial artificial forestshould be performed and the relation between specialized objective productionand ecosystem stability should be coordinated well by applying the methods andmeans of engineering design and, taking an ecological management region as a ba-sic unit area.
