在遥感和GIS技术的支持下,结合研究区湿地的区域特点确定沿黄湿地景观分类系统.构建了湿地景观格局变化表征模型,综合利用景观多样性指数、景观破碎化指数、景观要素斑块分布质心空间变化等景观格局指标和斑块数量,斑块面积、斑块平均面积、斑块数量等景观类型指标,比较系统地分析了近七年研究区湿地景观格局的动态变化.结果表明:①研究区湿地的分布面积呈显著下降趋势;②随着人类干扰强度的增加,景观多样性上升;③湿地景观要素中,稻田湿地、滩涂面积在减少,而水库坑塘、黄河面积都在不断增加.

With the support of remote sensing data and GIS, the classification system of wetland landscape of the region along the lower yellow river was established. Using the indexes of the landscape pattern index, such as landscape diversity index, landscape fragmentation index, distribution centroid and extended dimension, and landscape type index, such as patch number, patch area and mean patch area, the paper presented the dynamic change of wetland landscape pattern from 2002 to 2009. Results show that:(1) The total area of wetland reduces obviously. (2) Disturbed by human activity, landscape diversity index ascends. (3) During the last nearly 7 years, the total area of the rice wetland and mud flat decreases, while the area of other types increase.
