City river ecological restoration technology and Application Study Lei Zhao 1,a, Haipeng Ma 2,b 1,2Xinxiang School of civil engineering and Architecture Department, Henan, Xinxiang, azlyoo@163.com, bmhpeng123@163.com Keywords: City canal.Ecological technology.
The riparian zone is near from the water, and the soil nutrition, with high productivity [5].Riparian zone not only plays an important role in maintaining ecological system, but also from the engineering sense, it also plays an important role in maintaining the stability and security of the river.
City canal restoration goal is to reach restore some function canals objective by repairing the natural state of canal system. 4.2 city canal ecological restoration technology approach 4.2.1 water repair Including the city centralized sewage treatment engineering, wetland restoration project, land ecological engineering. 4.2.2 Repair of in water Including the purification ability of canals enhancement techniques, such as aeration, water diversion dilution, add reagents, biological control, the restoration of aquatic vegetation, water in biological enhancement; and control technology to eliminate endogenous, such as sediment transport sediment dredging, pollution control.
Generally speaking, the city can be divided into water type, type, type, garden city garden city type, different types of city should be in harmony with their green layout; ③Using the engineering methods, the formation of the natural environment.
Ecological revetment to overcome the traditional water conservancy engineering technology landscape effect is poor, the shortcomings of the poor hydrophilicity, flood prevention and bank protection function is reserved, and integrated into the ecological thought.

Structural damage detection of the simple beam based on responses phase space Cheng Cheng1,a, Zhenhua Nie2,b, Hongwei Ma3,c 1College of Science & Engineering, Jinan University, Guang Zhou, Guang Dong, China,510632 2The Key Laboratory of Disaster Forecast and Control in Engineering, Ministry of Education of China, Guangzhou, China, 510632 atmahw622@gmail.com, bcc391357271@163.com Keywords: Structural damage detection, Phase space reconstruction, Acceleration response, Time series, Simple beam.
However, these methods have a lot of difficulties in engineering application as these methods exist many problems such as they are mostly based on theoretical analysis, model test and simulation analysis.
In fact, in practical engineering, current methods still suffer from the same problems in judging damage existence and degree which play a very important role in structural heath monitoring.
However, using the chaotic sequence as excitation source in actual civil engineering structure is almost impossible, so the response under ambient excitation or impulse excitation must be studied.
