鄱阳湖湿地及其典型湖区1989-2010年空间分布与变化数据集

鄱阳湖高滩植被、苔草、碟形洼地、大湖面以及河道等类型湿地空间分布数据。赣江主支口与饶河口交汇处三角洲湿地与赣江南支口洲滩湿地两处位于鄱阳湖南北两端典型洲滩湿地植被分布格局数据。鄱阳湖全湖湿地数据中包含观测指标共7项，各项代码0-7在属性表中分别对应ct、ld、lw、nt、ss、tc、water项，代表稀疏草滩、裸地、高滩植被（芦苇群落）、泥滩、水生植物、苔草群落及水域七种景观类型。鄱阳湖典型区湿地数据中包含观测指标共3项，各项代码0-2在属性表中分别对应lw、tc、nt项，代表高滩植被（芦苇群落）、苔草群落及泥滩三种景观类型。所有影像合计大小约为41.2 MB。

Spatial distribution data of wetlands with various types including high-beach vegetation, Carex communities, dish-shaped depressions, large lake surfaces and river courses in Poyang Lake, as well as vegetation distribution pattern data of two typical fluvial bar wetlands located at the northern and southern ends of Poyang Lake respectively: one is the delta wetland at the confluence of the main tributary mouth of Ganjiang River and the mouth of Rao River, and the other is the bar flat wetland at the southern tributary mouth of Ganjiang River.
The full-lake wetland dataset of Poyang Lake includes 7 observation indicators, with codes 0 to 7 in its attribute table corresponding to ct, ld, lw, nt, ss, tc, and water respectively, representing seven landscape types: sparse grass flats, bare land, high-beach vegetation (reed communities), mudflats, aquatic plants, Carex communities, and water bodies.
The typical regional wetland dataset of Poyang Lake contains 3 observation indicators, with codes 0 to 2 in its attribute table corresponding to lw, tc, and nt respectively, representing three landscape types: high-beach vegetation (reed communities), Carex communities, and mudflats.
The total size of all included images is approximately 41.2 MB.
