| 摘 要： | 以浙江省80个重要湿地为研究对象,综合考虑景观、生物多样性及社会发展等多种因素,构建湿地生态状况评价指标体系。采用层次分析法(AHP)和德尔菲法,对13个评价指标进行分级和赋值,计算每处重要湿地生态状况的综合得分,定量表征湿地的生态状况。结果表明:浙江省生态状况评级为“好”的湿地有20个,评级为“中”的湿地有36个,评级为“差”的湿地有24个,分别占浙江省重要湿地总数的25%、45%和30%。浙江省重要湿地生态状况总体良好,但部分湿地存在水质污染、富营养化和外来物种入侵等问题。

| Abstract: | Based on the results of the Second Wetland Resource Survey in Zhejiang Province and the land-protecting arrangements of each region,80 important wetlands in Zhejiang Province were taken as the study sites and a database was established using Arcgis 10.2.We constructed a wetland ecological status evaluation indicators system and a variety of factors were taken into consideration,such as landscapes,biodiversity and social development.Using the analytical hierarchical process(AHP)and the Delphi methods,we graded and assigned 13 evaluation indicators and calculated the score of each important wetland.These enabled us to quantitatively reflect the ecological status of each wetland.In terms of ecological condition,20 wetlands were rated as"good",36 wetlands as"medium"and 24 wetlands as"poor",accounting for 25,45 and 30 percent respectively.The ecological status of these important wetlands in Zhejiang Province were generally good.Still,some wetlands were plagued by water pollution,eutrophication and invasion of exotic species. |
