title: 80 meter resolution wetland spatiotemporal evolution dataset of Liaohekou National Nature Reserve (1990)
title: 辽河口国家级自然保护区80 m分辨率湿地时空演变数据集（1990年）

description: a. Data content (data file/table name, including observation indicators)
This data includes a 30m resolution wetland distribution dataset of Liaohekou National Nature Reserve, reflecting the distribution of wetlands in Liaohekou National Nature Reserve and providing data support for wetland protection in Liaohekou National Nature Reserve.
b. Construction purpose
Wetlands have important ecological functions such as regulating climate, maintaining biodiversity, purifying water quality, and regulating and storing floods, and are an important component of the global carbon cycle. The Liaohekou National Nature Reserve, known as the "world's largest reed field," is one of the most well protected wetlands in the world and plays an important role in international wetland research and conservation. After years of transformation, this wetland has formed a current situation dominated by reed wetlands with multiple wetland vegetation coexisting, playing an extremely important role in flood storage, drought prevention, and environmental purification. At the same time, the region is not only an important production base for agricultural products such as oil, sea salt, rice, and reeds in China, but also a stopover and habitat for migratory birds in East Asia. In addition, the "Red Beach" landscape formed by large areas of Suaeda salsa is a famous tourist attraction both domestically and internationally. In recent decades, human activities such as land reclamation and construction projects have had a significant impact on the ecological environment of the region. Monitoring the spatial distribution dynamics of wetlands and surrounding landscapes is of great significance for formulating scientific wetland protection and restoration policies.
c. Service target
It can widely serve scientific researchers in wetland conservation, ecological monitoring and other related disciplines.
