摘要
松雅湖国家湿地公园是通过退田还湖工程恢复重建的人工湿地。利用1955年、1972年、1990年地形图资料和2011年卫星影像资料,对比分析松雅湖湿地公园范围内湿地面积的时空变化,从湿地生态功能等视角分析松雅湖湿地公园对长沙县社会经济发展的重要作用,研究结果表明,在当今城市化快速推进的大环境背景下,城市及近郊湿地面积快速下降、功能逐渐退化的趋势难以避免,但通过科学规划并组织实施,局部区域城市湿地退化趋势可以放缓并在一定范围内可逆。
Songya Lake National Wetland Park is a reconstructed wetland by means of returning the grain plots to lake. By combining with history data, topographic maps in 1955, 1972, 1990 and satellite images in 2011, the temporal and spatial variation of wetland area in the Park was determined, and it is indicated that the Songya Lake Wetland Park plays an important role in socio-economic development for Changsha County; under the background of promoting urbanization in modem time, it is difficult to avoid the trend of wetland area reduction and the degradation of wetland function in urban and suburbs. However, it is possible to slow down the trend of wetland reduction in parts of urban area and even could be reversible in a certain range.
