摘要： <正>城市化进程使得大量湿地被填埋，导致湿地的生态与社会服务功能丧失。建设城市湿地公园是湿地保护与合理利用的成功模式。笔者分析了规划建设中的秦淮河湿地公园对区域潜在的生态经济效益，结果表明：该公园建成后对南京江宁区社会经济发展，以及生态环境的改善具有较大的拉动作用，可使地区经济增长1.69%～3.03%，可新提供3900～7400个就业岗位，公园周边土地增值达102.3亿元，产生7.8亿元的代际净效益。

Abstract: The depression of the noise in AE (acoustic emission) signal released from a compressing particleboard based on wavelet function in MATLAB to61box was introduced. In addition, the two kinds of denoising methods between wavelet analysis and filter were compared. The results showed that wavelet analysis could be used in the dispose of the noise in AE signal well.
