祁连山国家公园冰川变化（1987-2006）

冰川变化的数据是将第一次冰川编目数据和第二次冰川编目数据先按祁连山国家公园边界进行剪裁，然后对二者进行Erase操作，得到祁连山国家公园区域内部的冰川增加和减少的数据，第一次冰川编目数据（简称“一次编目”）是1987年中国科学院寒区旱区环境与工程研究所完成的，第二次冰川编目（简称“二次编目”）是在2006年启动的科技部科技基础性工作专项“中国西部冰川资源及其变化调查”项目的支持下，中国科学院寒区旱区环境与工程研究所冰冻圈科学国家重点实验室利用最新的遥感数据进行编制的。数据的属性字段有：AREA（面积）、PERIMETER（周长）、变化、GLACIER_ID（冰川编号）。数据格式为shp。

Glacier change datasets were generated by first clipping the First Glacier Inventory (primary inventory) and the Second Glacier Inventory (secondary inventory) using the boundary of the Qilian Mountains National Park, then performing an Erase operation on the two clipped datasets to obtain the data on glacier gains and losses within the Qilian Mountains National Park. The First Glacier Inventory was completed in 1987 by the Cold and Arid Regions Environmental and Engineering Research Institute (CAREERI), Chinese Academy of Sciences (CAS). The Second Glacier Inventory was compiled in 2006 by the State Key Laboratory of Cryospheric Science, CAREERI, CAS, under the support of the Special Program for Basic Scientific and Technological Work of the Ministry of Science and Technology of China, with the project title "Investigation of Glacier Resources and Their Changes in Western China", using the latest remote sensing data. The attribute fields of the dataset include AREA, PERIMETER, Change, and GLACIER_ID. The data is stored in shapefile (.shp) format.
