Metric Options: Counts1 Year3 YearSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
In order to evaluate the effect of Grain for Green Policy in the reach from Hekouzhen to Tongguan of the Yellow River, based on dryness/wetness, geomorphic type, slope gradient and aspect, from macroscopic to microcosmic, three indicators, including (a) a land use change significance index, (b) a land use change proportion (c) a vegetation change index, are used to characterize the primary transformation types, the intensity of land use changes, and the degree of vegetation restoration in the period 1998-2010. The results show that: (1) The area of land use change accounted for 19.19% of the study area. High coverage grassland, forest, and other woodland increased significantly, while low coverage grassland, farmland decreased markedly. (2) Spatially, land use change was found primarily west of the Yellow River, between 35 and 38 degrees north latitude, including Malian River basin, Beiluo River basin, Yanhe River basin. (3) The transformation types, including low coverage grassland to moderate coverage grassland, moderate coverage grassland to high coverage grassland, farmland to other woodland, shrub to forest were the primary types resulting from land use change. (4) The effect of dryness/wetness, geomorphic type and slope gradient on land use change was significant, but that of aspect on land use change was not so clear.
