Water Plant Cover Ijsselmeer area — Furnished Fountain wort — 2011

Waterplant cover IJsselmeer area. The water plant cover in the IJsselmeer area is monitored every three years. That is to say, in a three-year cycle, the aquatic plant cover is identified in each part of the area: in 2016 in the Markermeer and IJmeer, in 2017 in the IJsselmeer, and in 2018 in the edge lakes. N.B.: the Veluwemeer was not covered in 2018 but in a limited number of locations.For each year there is a dataset per species of aquatic plants found and a dataset with the total coverage present. These datasets concern interpolated data. In addition, there is a dataset per year with the (point) locations of the field observations.In this dataset, information from the years 2011 to 2018. Overall, the zone of 0-3 meters depth is serrated. See the “Point Map field observations” layer for a view of the measuring points. Watch it! Aquatic plants can also occur outside the serrated zone.艾瑟尔湖（IJsselmeer）区域水生植物覆盖情况数据集。艾瑟尔湖区域的水生植物覆盖度每三年开展一次周期性监测。换言之，该区域的水生植物覆盖度调查以三年为一个循环周期：2016年对马尔肯湖（Markermeer）与艾米尔湖（IJmeer）开展调查，2017年覆盖艾瑟尔湖（IJsselmeer）主体区域，2018年则针对沿岸湖泊进行调查。注意：2018年未对韦卢韦迈尔湖（Veluwemeer）开展全域监测，仅在少量点位进行了采样调查。每年度的数据集包含两类：一类为对应年度检出的各水生植物物种的覆盖数据，另一类为该年度的总水生植物覆盖度数据。上述数据集均基于插值生成的数据。此外，每年度还附带一份野外实地观测的点位坐标数据集。本数据集整合了2011年至2018年的相关监测信息。整体而言，0至3米水深的区域呈锯齿状分布。可通过「Point Map field observations」图层查看监测点位的具体分布。请注意：水生植物也可能出现在该锯齿状分布带以外的区域。
