| 摘 要： | 该文阐明了伐区生产工艺平面图系统开发的思想与方法.系统采用面向对象技术,在Windows环境下运用可视化的编程语言Visual Basic 6.0开发,提出2种绘制伐区生产工艺平面图的方法:其一为矢量法.由外业测量数据的输入,经系统处理得出面积、闭合差,并最终形成矢量图形文件;其二为栅格法.采用方格法计算伐区面积,经扫描输入的图像,由系统处理形成栅格图形文件.系统由数据输入(或扫描输入)、系统处理、打印3部分组成,能完成伐区生产工艺平面图的绘制和打印,并纳入了伐区的森林采伐更新调查内业设计.

| Abstract: | This paper deals with the principle and approach for developing the designing system for productive technical plane figures of cutting areas. A software is developed, using the object\|oriented techniques and the visual programming language of Visual Basic 6.0 under the environment of Windows. Two methods to draw productive technical plane figures of cutting areas are developed in the paper:one is vector, by which surveying data are put into system and processed to calculate the area and closing error, and finally graphical file is established in vector format. The other is raster, in which way cutting area is calculated by using squared paper, and then the scanned picture is processed to establish a file in raster format. The system, composed of data inputting, data processing and figure plotting, can draw and print the productive technical plane figures of cutting areas, also can be applied in forest cutting and reforestation investigation design of cutting areas. |
