摘要
摘要:基于扎龙湿地1980—2015年7期土地利用数据、近35年气象数据和统计年鉴数据，利用数理统计、空间分析与景观格局指数等方法，对扎龙湿地近年来景观类型时空变化、景观格局变化及驱动因素进行分析，并对生态环境保护措施等问题进行探讨．结果表明：1）近35年来，扎龙湿地西北、中东和西南部地区景观类型空间变化明显，受人类干扰严重．沼泽地面积减少最多，耕地面积增加最多，草地、林地、未利用地面积有不同程度的增加，水域和建筑用地面积变化不大．2）在1995—2005年扎龙湿地景观破碎度较高，且2000—2005年变化显著．耕地、林地和草地面积增加，水域、沼泽地面积减少对景观破碎化有直接影响．3）温度增加使湿地水体的潜在蒸发量增大，影响湿地水量平衡．大型水利设施、补水工程的修建有效缓解湿地缺水状况，同时也打破湿地的自然生态水文模式，加剧湿地景观破碎化．随着社会经济的快速发展和城市化进程的加快，湿地生态系统功能与可持续发展都面临重大挑战．

Abstract:Wetlands have important functions in protecting biodiversity, regulating floods and runoff．The 7th period of land use data for Zhalong Wetland from 1980 to 2015, meteorological data of the past 35 years and statistical yearbook data were used for mathematical statistics, spatial analysis and landscape pattern index, to analyze the temporal and spatial changes in landscape types and landscape patterns in Zhalong Wetland. Changes and their driving factors．Issues such as ecological environmental protection measures was discussed．The landscape types in the northwest, middle-east and southwest of Zhalong Wetland were found to have changed significantly in the past 35 years, been seriously disturbed by human activities．The total area of marshland was found to have decreased the most, total area of arable land increased the most, total area of grassland, woodland and unused land increased to varying degrees, but area of water and construction land remained unchanged．The Zhalong wetland landscape was highly fragmented from 1995 to 2005, such changes were significant from 2000 to 2005．Increases in arable land, woodland and grassland, decreases in waters and swamps were found to have direct impacts on fragmentation of landscape．Increased temperatures enhanced potential evaporation of wetland water bodies, affecting wetland water balance．The construction of large-scale water conservancy facilities and water replenishment projects effectively alleviated the lack of water in wetlands, at the same time broke the natural ecological hydrological model of wetlands, and aggravated fragmentation in wetland landscapes．It is concluded that with rapid development of social economy and acceleration in urbanization, the function and sustainable development of wetland ecosystems are facing major challenges．
