A dataset of vector elements for Cladophora blooms in Qinghai Lake(1986-2023)
摘要
Abstract
Cladophora is a benthic filamentous green algae with elongated cellular morphology and fine hair-like projections.Its rapid growth and strong attachment allow it to proliferate quickly under suitable environmental conditions,and it will detach from the substrate and float on the surface of the water to form yellowish-green water blooms under strong wind disturbance or its own physiological deterioration.The frequent outbreaks of the Cladophora blooms in the shallow waters along the Qinghai Lake have damaged the ecological landscape and diminished the tourism value in the area.It is urgent to carry out the monitoring of Cladophora blooms in the whole lake area and understand their spatial and temporal changing patterns.Based on Landsat TM/ETM+/OLI and Sentinel-2 MSI cloudless remote sensing images,the Floating Algae Index(FAI)method and manual visual revision were used to obtain a dataset of vector elements for Cladophora blooms in Qinghai Lake from May to October(1986-2023).The resulting vector dataset includes information such as the location,area,length and remote sensing image sources of each bloom patch.Validated by UAV imagery,the dataset demonstrates high accuracy and provides data support for the governmental authorities and the management department of Qinghai Lake National Nature Reserve to monitor the dynamics of Cladophora growth in Qinghai Lake in a timely manner and formulate corresponding preventive measures.关键词
