摘　　要：在黄河三角洲湿地试验区内,选择了人工干扰程度不同的4个区,并在每个区样地中设置样方,测量植被的多样性,调查植被的种类、盖度等,拟比较不同程度人工干扰下植被的群落组成结构,寻求黄河三角洲不同人工干扰下的湿地群落组成及成因,结果表明:由于人工的干预,特别是在部分地区黄河水的人工调入,改变了植物群落的自然格局。人工干扰对土壤含盐量和含水量的改变,是影响植被种群格局的关键因素。同时指出,黄河三角洲的开发正在进入一个新的时期的背景下,发展林业十分必要。Vegetation species and coverage of wetland community in four regions were surveyed in Yellow River Delta by setting quadrats in every sample plot in order to compare the species diversity and community composition under different humaninduced disturbances and to study the distribution pattern in different regions and its causes. Results showed that the human-induced disturbance, especially the water transfer from the Yellow River in some regions, resulted in the change of natural spatial distribution pattern of vegetations. Changes in soil salinity and soil water content are the key factors influencing the spatial distribution pattern of vegetations. The development of the Yellow River Delta is entering a new period, and in such circumstances the development of forestry is very necessary.
