| 摘 要： | 针对沿海滩涂围垦的特点,选取反映和体现滩涂围垦对生态环境影响的指标(自然生态指标、环境质量特征指标、生态保护措施指标)对上虞围垦滩涂进行生态评价。运用层次分析法对生态评价因子进行等级化处理,确定各评价指标的权重,计算各生态评价因子的评价指数,得出1984年围垦的八四丘滩涂和2000年以后围垦的世纪丘滩涂的综合评价指数分别为80.7和65.3。指出滩涂围垦过程中,措施得当,可减少滩涂围垦对生态环境的负面影响。 |

| Abstract: | By employing a series of index which reflect the ecological influences of tidal flat reclamation on the ecosystem resbuilt,Shangyu Tidal Flat located in Zhejiang in the eastern China was ecologically investigated and evaluated. These index reflected the status of the ecosystem from natural flora,environmental quality and property, and environmental conservation. By AHP-based scoring, indice weighting,environmental index(EI)of employed ecological factors calculating, two reclamated tidal flats,named with 1984zone and 2000zone respectively,were evaluated out with EI of 80.7 and 65.3 respectively,which implied that the tidal flat built in 1984 had a better ecosystem quality than that built in 2000. It suggested that well-managed reclamation of tidal flat can result a less adverse influence of reclamation and quicker establishement of healthy agroforestry ecosystem. |
