摘要：以土地变化科学理念为指导,遥感和GIS为技术支持,应用景观生态学的理论和方法,定量化分析和研究1986~2000年东北地区沼泽湿地动态变化特征及其时空分布格局。通过对研究区域内沼泽湿地时空动态变化程度、动态方向、动态变化形式以及景观格局变化和景观转化特征的分析后得出结论。研究表明,15年来东北地区沼泽湿地面积和斑块数总体呈下降趋势。景观动态变化方面,虽然后5年年均缩减速率是前10年的28倍,但前10年是东北地区沼泽湿地景观斑块变化相对剧烈的阶段。纵观近15年来东北沼泽湿地景观总体变化,具有：虽有阶段性扩展但总体减少、局部萎缩、边界扩散程度加强、景观破碎化程度显著等特点。就其驱动因子研究表明,沼泽景观在自然因素和人为因素双重驱力的作用下,形成独特的景观空间格局。
According to the directing idea of LCS,employed the methods and theories of landscape ecology and based on remote sensing and GIS technique,the dynamic change of marsh in Northeast China was analyzed by quantification.Through researching on the spatial dynamic pattern of marsh landscape,such as dynamic degree,direction,and the transforming relationship between the major landscape types and its related land cover types,we traced the spatial-temporal variation pattern of marsh landscape from year 1986 to 2000.The research showed the general dynamic trend of marsh in Northeast China was that the area had been reducing,and the average reduced rate of the last five year is 28 times as fast as the before 10 years.The variation of the landscape patches in the first 10 years was more tempestuous than that in the last 5 years.Although the amount of the patches was declined,the fragmentation degree was rising,and the shape of the patches was more and more irregular.From the analysis on marsh landscape transformation,we gained the result that the area of marsh conversed into dry land was biggest,that was to say,the most important reason in the reduction of marsh area was mankind reclamation.Secondly,because the climate had been becoming dryer and dryer,some marsh deteriorated to lawn,and it played an important role in education.In addition,it was evidence to the conversion from lake to marsh that the climate was becoming dryer.The unique spatial pattern of marsh landscape in Northeast China was formed driven by both natural factors and human factors.
