祁连山天老池流域草地截留数据集

该数据包含草地截留控制实验数据和草地最大持水量观测数据。
最大持水量实验是2011年进行的，主要选择的植被类型有苔草、珠芽蓼、车前草和委陵菜，对每种类型的样品进行最大持水量实验，并对其进行照相处理，得到的具体数据见文件。
草地冠层截留是2012年生长季进行的，采用人工控制降雨实验来完成。在生长季末期，对流域内主要类型草地按照放牧与禁牧两种情况进行采样。人工降雨过程中，每隔1min对降雨量和穿透雨量进行记录，最后通过降雨量与穿透雨量的差值计算草地冠层截留量。

This dataset contains two core datasets: data from grassland interception control experiments and field observations of grassland maximum water-holding capacity.

The maximum water-holding capacity experiments were conducted in 2011. The dominant vegetation types selected for the experiments included Carex, Polygonum viviparum, Plantago asiatica, and Potentilla. For samples of each vegetation type, maximum water-holding capacity tests were performed, with accompanying photographic documentation. Detailed experimental data are provided in the accompanying files.

Grassland canopy interception experiments were carried out during the 2012 growing season using artificially controlled rainfall simulations. At the end of the growing season, sampling was conducted on major grassland types within the watershed under two management treatments: grazing and grazing exclusion.

During the artificial rainfall procedure, rainfall amount and throughfall amount were recorded at 1-minute intervals. Finally, grassland canopy interception was calculated as the difference between the recorded total rainfall amount and throughfall amount.
