一、设计思想森林采伐调查设计手工作业的主要问题是效率低、质量差,而伐区设计规范化程度高,整个过程具有较强的内在联系。这正是微机最能发挥效果的所在。系统数学模型的建立必须力求满足用户的使用要求,但又不能局限于对现实的简单模拟。伐区设计微机系统的数学模型,忠实于手工设计作业中的科学成分,但对其中存在的不严密、不统一、不合理的项目,如各树种的林龄计算,实际蓄积量的计算等,还需由省厅主管部门、使用单位、软件开发单位共同研讨、重新进行规范,然后建立数学模型。
First, the design idea The main problems of manual design of forest harvesting survey design is inefficiency, poor quality, but the high standardization of cutting area design, the whole process has a strong internal relationship. This is where the best computer can do. The establishment of system mathematical model must strive to meet the user’s requirements, but not limited to the simple simulation of reality. The mathematical model of the computer system of cutting area design is faithful to the scientific components of the manual design work. However, for those items that are not rigorous, uniform or unreasonable, such as the calculation of the age of the trees and the calculation of the actual storage volume, Also required by the ministries and departments, the use of units, software development units to discuss, re-regulate, and then establish a mathematical model.
