三峡运行对洞庭湖典型丰、枯年份水位影响分布图（2006、2010）

该数据集为典型丰水和枯水年三峡运行对洞庭湖水位影响程度和差异的空间分布图。两幅影响中，Change20061014.tif表示典型枯水年，三峡水库蓄水期对洞庭湖水位影响最大值的空间分布；Change20100730.tif表示典型洪水年，三峡水库调蓄对洞庭湖最高洪水位影响的空间分布。该数据集为数值模型模拟数据，数据集为栅格数据格式，坐标采用北京1954坐标系,网格大小为100m*100m。

This dataset provides spatial distribution maps demonstrating the extent and discrepancies of the impacts of Three Gorges Reservoir operation on Dongting Lake's water levels during typical high-flow and low-flow years. Among the two raster files, Change20061014.tif represents the spatial distribution of the maximum impact of Three Gorges Reservoir impoundment on Dongting Lake's water levels during the impoundment period of a typical low-flow year; Change20100730.tif depicts the spatial distribution of the impact of Three Gorges Reservoir regulation on the highest flood water levels of Dongting Lake during a typical high-flow year. This dataset is sourced from numerical model simulation data, formatted as raster data, utilizing the Beijing 1954 Coordinate System, with a grid size of 100m × 100m.
