摘要:
为了探究鄱阳湖汛期水体面积变化的影响因子,基于1977—2017年汛期鄱阳湖流域遥感影像数据、流域内同期6个控制水文站实测汛期月径流量及流域内1980—2015年土地利用资料,运用Mann-Kendall趋势与突变检验及突变检验方法分析了鄱阳湖流域汛期湖泊水体面积、湖区流失入江径流量变化趋势特征以及流域内土地利用结构变化特征。结果表明:鄱阳湖汛期水体面积呈减小趋势,且在2005年发生突变; 汛期湖区净出湖径流量呈逐年显著增加趋势,发生突变年份为1990年; 20世纪90年代城乡工建用地面积大幅增大,未利用土地面积大幅减少,导致流域耗水量增大。汛期净出湖径流量增加是造成汛期湖泊面积减小趋势的主要原因之一; 流域内“退田还湖”等生态工程的实施有利于缓解汛期湖泊水体面积减少趋势; 长江上游水利工程建设、流域内城镇化发展等人类活动是鄱阳湖汛期水体面积减少的主要驱动因素。
Abstract:
As the largest freshwater lake in China, Poyang Lake's water area change and its driving factors have attracted attention from all sectors of society. In order to explore the influencing factors on water area change in Poyang Lake during flood season, the remote sensing image data of Poyang Lake Basin during flood season from 1977 to 2017, the measured monthly flow in flood season from six control hydrological stations in the same period and the land use data in the basin from 1980 to 2015 were analyzed. Mann-Kendall trend and mutation test and mutation test methods were used to analyze the characteristics of water body area, runoff and land use structure change in the Poyang Lake Basin during flood season. The results showed that: the water area of Poyang Lake in flood season showed a decreasing trend, and the abrupt change occurred in 2005; the net runoff of the lake increased significantly year by year in flood season, and the mutation year was 1990; in the 1990s, the area of land used for industrial construction in urban and rural areas increased greatly, while the area of unused land decreased greatly, leading to the increase of water consumption in the basin; the increase of net runoff from the lake in flood season was one of the main reasons for the decreasing trend of lake area in flood season. The implementation of ecological projects such as returning farmland to lake in the basin is beneficial to alleviate the decreasing trend of lake water area in flood season. Human activities such as water conservancy projects in the upper reaches of the Yangtze River and urbanization development in the basin are the main driving factors for the decrease of water area of Poyang Lake in flood season.
