摘要
对纳帕海自然保护区3个冬季水体变化与越冬水禽种类数量变动进行观察,结果表明:水体面积大,水鸟种类数量多;水体面积小,水鸟种类和数量少,两者呈正相关。依据观察结果,提出在冬季应当人为干预生境变化,保持适度的水域面积。
The variation of water body area and the number of overwintering waterfowl species in Napahai Nature Reserve were successively observed for three years. The observation indicated that the bigger water body area sustained, the more waterfowl species observed, and vice versa. There was a positive correlation between the water body size and the number of waterfowl species. It was proposed according to the observation that a proper human in- tervention to the winter habitat was required for the waterfowls in order to maintain a moderate water acreage.
