摘要
2013年1月~2015年2月,对陕西省黄河湿地自然保护区内大鸨越冬生境进行了调查。共记录实验样方及对照样方各64个,统计栖息地生境中植物种类、植物平均高度、草本盖度、水源距离、最近路距离等15项参数,利用因子分析等方法从大鸨栖息地生境中提取出五个主因子,食物质量因子、持续性干扰因子、食物丰度因子、偶发性干扰因子、隐蔽条件因子是大鸨选择栖息地的主要因子。食物因素和干扰因素为大鸨栖息地选择的关键因素。鼓励农民种植小麦等大鸨食物,增加越冬期保护区内大鸨食物量,改变传统牧牛、羊散养方式,加强宣传是保护本区内大鸨生境的重要途径。
The wintering habitat select of Great Bustard in the Yellow River wetland, Shaanxi province were investigated from January 2013 to February, 2015. Total 64 experimental samples and 64 control samples were recorded. The 15 habitat parameters of were statistics, such as plant species, the average height, herb coverage, distance to water source, the recent road distance and so on. By using the method of factor analysis to extract the five main factors from habitats of Great Bustard, believe that the factors of food quality, persistent disturbances, food abundance, sporadic disturbance and hidden factor are the main factors affected on habitat selection of Great Bustard. The food factors and interference factors are key factors of Great Bustard's habitat selection. Encouraging farmers to grow wheat and other great bustard's food, increase the food quantity of the wintering period, change the way of traditional grazing,strengthen the propaganda are important ways to protect the habitat area of Great Bustard.
