摘    要:河湖沼系统具有重要的水资源涵养及调节功能,对我国的经济发展、生态保护等具有十分重要的意义。本研究以中国河湖沼系统为研究对象,以土地利用类型数据为基础,采用ArcGIS空间分析法、转移矩阵及相关系数计算等方法,核算探究1990至2015年中国河湖沼系统水面率的时空变化特征及迁移转换趋势,在此基础上,定量及定性对我国河湖沼系统的变化驱动力影响开展分析及讨论。结果表明:(1)河湖沼系统主要分布在我国的东部地区,其中东北地区分布最为广泛,其次是长江区域中下游和西南地区;(2)我国河湖沼系统水面率在1990-2010年总体变化幅度较小,而2010-2015年有所增加,且河湖沼系统中水面率沼泽>湖泊>河流;(3)1990-2015年河湖沼主要与耕地、草地和林地之间发生地类的迁移转换,其中沼泽与草地间的迁移转化趋势更明显;(4)相关系数结果表明,人为因素与河湖沼系统变换相关性更显著,是河湖沼系统短期内时空变化的主要原因;自然因素对河湖沼系统时空变化的影响持久且稳定。本研究结果可为国家合理规划和配置水资源提供基础,对保障我国经济健康可持续发展具有重要意义。

关 键 词:中国  河湖沼系统  时空变化  驱动力。

Abstract:The river-lake-marsh system is so important for maintaining the function of land surface water system, which is of great significance to the national economic development and ecological protection. In this study, based on the land use data, we tried to describe the spatiotemporal change characteristics of China''s river-lake-marsh system from 1990 to 2015 using the ArcGIS spatial analysis, Transfer Matrix and Correlation Coefficient methods. On this basis, quantitative and qualitative analysis have been carried out to explore the driving force for the changes in the river-lake-marsh system. The results showed that (1) The river-lake-marsh system is mainly distributed in the eastern part of China, of which the northeast is the most widely distributed, followed by the middle and lower reaches of the Yangtze River region and the southwest region. (2) From 1990 to 2010, the overall change in the water surface rate of the river-lake-marsh system in China is relatively small, but increased from 2010 to 2015; and the water surface rate in the system is swamp > lake > river. (3) From 1990 to 2015, rivers, lakes and marshes mainly migrated and transformed between farmland, grassland and woodland. Among them, the migration and transformation trend between swamp and grassland was more obvious. (4) The correlation coefficient results showed that the correlation between human factors and the transformation of the river-lake-marsh system is more significant, which is the main reason for the temporal and spatial changes of the system in the short term; natural factors have a lasting and stable influence on the system. The results of this study can provide a basis for the national rational planning and allocation of water resources.
Keywords:China  River-lake-marsh system  Spatial-temporal changes  Driving force
