阿姆河流域土地利用分布图（1990,2000,2010,2015）

阿姆河流域土地利用分布图包括1990年、2000年、2010年和2015年四期数据，由中国科学院新疆生态与地理研究所遥感与GIS重点实验室生产，数据空间分辨率为30m。数据生产费用由“中国科学院战略性先导科技专项XDA20030101资助”。阿姆河流域土地利用分布图是基于1990年、2000年、2010年和2015年TM、ETM遥感影像数据，基于去云、镶嵌与裁剪、拼接、阴影处理等预处理，借助eCognition软件进行面向对象的地类分类，实现软件自动分类和人工信息提取相结合，最后对分类结果进行人工检查与修正。土地利用类型二级类有25个，分别是水田、水浇地、旱地、有林地、灌木林地、疏林地、其他林地、高覆盖度草地、中覆盖度草地、低覆盖度草地、城镇用地、农村居民点、其他建设用地、机场用地、河渠、湖泊、水库坑塘、永久性冰川雪地、滩地、沙漠、戈壁、盐碱地、湿地、裸土地和裸岩石砾地。数据验证方式为野外实地验证和高精度影像验证两种方式，解译精度达到85％。

The Land Use Distribution Map of the Amu Darya Basin includes four phases of data from 1990, 2000, 2010 and 2015, which was produced by the Key Laboratory of Remote Sensing and GIS, Xinjiang Institute of Ecology and Geography, Chinese Academy of Sciences, with a spatial resolution of 30 meters. The production of this dataset was funded by the Strategic Priority Research Program of the Chinese Academy of Sciences (Grant No. XDA20030101). This map was developed based on TM and ETM remote sensing imagery from the four aforementioned years. Preprocessing steps including cloud removal, mosaic and cropping, image splicing and shadow correction were first conducted. Then, object-oriented land classification was carried out using eCognition software, combining automatic software classification with manual information extraction. Finally, the classification results were manually inspected and revised. There are 25 secondary land use types in total, specifically paddy field, irrigated cropland, dryland, closed forest land, shrub land, open forest land, other forest land, high-coverage grassland, medium-coverage grassland, low-coverage grassland, urban land, rural settlements, other construction land, airport land, rivers and canals, lakes, reservoirs and ponds, permanent glaciers and snowfields, river flats, desert, Gobi, saline-alkali land, wetlands, bare land and bare rock and gravel land. The dataset was validated through two methods: field survey and high-resolution image verification, with an interpretation accuracy of 85%.
