摘要
采用模糊综合评价法 ,以游禽、涉禽及珍稀濒危物种的种类和数量为评价因子 ,对天津地区 5处水鸟栖息地的保护等级进行了评价 .评价结果表明 ,北大港水库得分 0 .996 ,属极其重要等级 ,团泊洼水库、尔王庄水库和七里海水库得分分别为 0 .72 6 ,0 .5 0 4 ,0 .5 18,均属较重要等级 ,西河岳龙湿地得分 0 .4 76 ,属一般等级 .因此 ,北大港水库、团泊洼水库、尔王庄水库和七里海水库应得到重点保护 .西河岳龙湿地是一个重要的灰鹤越冬场所 ,应注意在灰鹤越冬季节内对该地区的保护 .天津案例表明 ,模糊综合评价法在利用现有水鸟调查数据对水鸟栖息地的保护等级进行综合。
Fuzzy Synthetic Method is used in the evaluation of the waterbird habitat conservation grade of Tianjin. The species and number of the Natatorial birds, wading birds and protected birds are selected as the evaluation factors. The importance of the waterbird habitats is classified into 4 grades: very important,important, common and bad. The results suggest that the Beidagang reservoir belongs to the very important grade and it should be given priority in conservation. Tuanbowa, Erwangzhuang and Qilihai belong to the important grade, these three habitats should also be protected. Although Xihe Yuelong belongs to the common grade, it should be protected in winter because it is an Common Crane( Gxul arul ) wintering habitat. The Tianjin case study indicates that Fuzzy Synthetic Method can play an important role in the comprehensive and quantified evaluation of the waterbird habitat conservation grade.
