本文从原理上阐述与森林资源动态监测有关的几个主要问题,兼评系统动力学模型。
Based on the principal, this paper deals with some problems concerned with the dynamic monitoring for forest resource and comments on the system dynamic model in the meantime.
因此,在制定正确的森林经营决策之前,首先必须建立林分生长与收获模型,以掌握林分结构、生长动态、货币收获变化规律,并预测林分对即将实施措施的反应。
Thus, the growth and obtain models must be established before making the proper manage decision, the structure and grow dynamic and obtain change rule of the stand will be grasped by the models.
同时模型根据土壤水贮量变化来模拟月森林水量平衡,它详细模拟了大气降水,地下水、人工灌溉、林分蒸腾量、渗透水量和土壤水之间的动态变化。
At the same time, in view of the change of soil water storage, it simulates dynamitic change among atmospheric rainfall, groundwater, irrigation, forest transpiration, deep drainage and soil water.
