地球资源卫星象片的应用,在国内外已受到极大的重视.尤其在野外土地资源调查中,发挥了较好的作用.因为卫片比地形图有直观的优点,以它编制中小比例尺土地资源图,不仅能节省大量人力与时间,而且为编图提供了可靠的信息和内容,并提高了制图精确度和质量.辽东半岛三面环海,一面着陆,境内地形复杂多变.该地区沿海及河流下游为平地和海涂,其余大部分为山地丘陵.因受人为活动影响,植被类型十分复杂,有天然林、次林、人工林和果园,农作物类型亦多种多样.在如此复杂多变的地貌类型和自然景观下,若按一般方法编制土地资源图,往往事倍功半.为此,我们在编制辽东半岛旅大幅土地资源图时,曾以各类卫片和影象地图的图形大小、色调、结构和地貌等特征为主要解译标志,并参照不同比例尺的地形图、土壤图、地质图、植被图、森林分布图及不同波段的黑白卫片进行对比研究,较好较快地做出了土地资源图.
The application of earth resources satellite imagery has received great attention both at home and abroad, especially in field investigation of land resources.As the satellite tablet has an intuitive advantage over topographic maps, Resource map, not only can save a lot of manpower and time, but also provide reliable information and content for the compilation, and improve the accuracy and quality of mapping.Around Liaodong Peninsula surrounded by the sea, while landing, the terrain is complicated and changeable. And the lower reaches of the river are flat and tidal flats, most of which are mountainous hills. Due to the impact of human activities, the types of vegetation are very complex with natural forests, secondary forests, plantations and orchards, and the types of crops are also varied. Of the landscape types and natural landscape, according to the general method of preparation of land resources map, often more effective and less than half.To this end, when we in the preparation of large land resources Liaodong Peninsula Tour map, with various types of satellite images and map the map size, color , Structure and geomorphology as the main interpreter signs, and with reference to different scales of topographic maps, soil maps, geological maps, vegetation maps, forest distribution maps and different bands White Guardian piece comparative study, quickly made a better land resource map.
