那曲高寒草地生态系统野外科学观测研究站冬季增温试验物候相机照片集（2023）

该数据集来自那曲高寒草地生态系统野外观测研究站冬季增温试验平台，增温方式为六边形开顶式气室（Open Top Chamber，简称OTC），包括不增温对照和冬季增温两种处理，冬季增温时间为11月中旬至次年3月，冬季增温处理又设置OTC三个高度（60 cm、80 cm、100 cm），每个处理四个重复。生长季期间每天9-18点定时拍照，时间间隔1小时。拍照时间和样方编号内置于照片文件，数据未加工。该数据质量较高，为研究青藏高原高寒草甸对气候变化的响应提供基础数据。

This dataset is sourced from the winter warming experimental platform of the Nagqu Alpine Grassland Ecosystem Field Observation and Research Station. The warming method adopts hexagonal Open Top Chambers (OTC for short), with two treatments including non-warming control and winter warming. The winter warming period runs from mid-November to March of the following year. For the winter warming treatment, three OTC heights (60 cm, 80 cm, 100 cm) are set, with four replicates per treatment. During the growing season, photos are taken regularly from 9:00 to 18:00 daily at 1-hour intervals. The photo capture time and quadrat number are embedded in the image files, and the data remains unprocessed. This dataset is of high quality and provides foundational data for studying the responses of alpine meadows on the Qinghai-Tibet Plateau to climate change.
