河流中管理不善的塑料垃圾数据集该数据集显示了2015年全球河流受管理不善的塑料废物（MPW）影响的情况，以及根据三种情况预测的2060年的影响。2060年的不同情景是：A：一切照旧；B：改善塑料回收；C：改善塑料回收和减少塑料使用的预测。前言 – 床长人工智能教程

有四个全球数据集，包括

2015年和2060年三种情况下的MPW、河流类型（例如，蜿蜒或辫状）。过去36年中河流的迁移情况以及人类对河流的影响。数据集在《总体环境科学》上发表的论文中作了进一步的详细描述https://www.sciencedirect.com/science/article/pii/S0048969723004369，在Zenodo数据存储库或使用这里的互动地图。Legacy of MPW in Rivers

管理不善的塑料垃圾数据集

Band 'MPW2015' = MPW input in 2015
Band 'MPW2060A' = MPW input in 2060 based on a 'business as usual' projection.
Band 'MPW2060B' = MPW input in 2060 based on an 'improved plastic recycling' scenario.
Band 'MPW2060C' = MPW input in 2060 based on an 'improved plastic recycling and reduced plastic demand' scenario.
Band 'FFPW2015' = Potential plastic accumulation in 2015.
Band 'FFPW2060A' = Potential plastic accumulation in 2060 based on a 'business as usual' projection.
Band 'FFPW2060B' = Potential plastic accumulation in 2060 based on an 'improved plastic recycling' scenario.
Band 'FFPW2060C' = Potential plastic accumulation in 2060 based on an 'improved plastic recycling and reduced plastic demand' scenario.

Values for MPW datasets

1000 = Very High impact (> 10 t/yr/km2)
2000 = High impact (1 to 10 t/yr/km2)
3000 = Moderate Impact (0.1 to 1 t/yr/km2)
4000 = Low Impact (< 0.1 t/yr/km2)
5000 = None

Values for FFPW datasets

1000 = Very High impact (> 100 t/yr/km2)
2000 = High impact (10 to 100 t/yr/km2)
3000 = Moderate Impact (1 to 10 t/yr/km2)
4000 = Low Impact (< 1 t/yr/km2)
5000 = None

River Type Dataset

Code 0 = No Data/Background
Code 1 = Meandering/Single-threaded River
Code 2 = Braided/Multi-threaded River
Code 3 = Lacustrine/Wetland Environment

River Migration Dataset

Code 0 = No Data/Background
Code 20 = Actively migrating river over 36-years of satellite observations
Code 30 = Permanent river waterbody over 36-years of satellite observations

River Impact Dataset

Code 0 - No Data/Background
Code 100 - Free Flowing River
Code 200 - Good Connectivity River
Code 300 - Impacted River
