1981—1983年,新疆林业厅派员对天山林区、阿尔泰山林区、塔里木河流域林区进行了全面的航空摄影,获得了各该地区象幅为23×23厘米、平均比例尺约1:25,000的大量新的黑白遥感资料(以下简称图象),还对个别地区拍摄了1:10,000的大比例尺象片、红外彩色片和不同比例尺的多光谱片.如何利用这些图象开展森林资源及各类林业调查、各级林业区划,是一项迫在眉睫的工作.研究这些黑白图象主要森林类型判读特征,对于训练判读人员,提高判读质量,为今后开展大比例尺测树判读和有监督电子计算机自动识别分类等,有着重要意义.
In 1981-1983, the Xinjiang Forestry Department dispatched officers to conduct a comprehensive aerial photography of the Tianshan forest area, the Altai mountain forest area and the Tarim River basin forest area, obtaining 23 × 23 cm elephants in each area with an average scale of about 1: 25,000 A large number of new black and white remote sensing data (hereinafter referred to as the image), but also for individual areas of the 1: 10,000 large-scale film, infrared color film and multi-spectral film at different scales how to use these images for forest resources and various types Forestry investigation and the division of forestry at all levels are an urgent task.It is very important to study the interpretation characteristics of the main forest types in black and white images and to improve the interpretation quality for the training of interpreters so as to carry out large-scale tree measurement interpretation and supervised electronic computer automatic identification Classification, etc., has important significance.
