声级计其操作简单,方便,成本低,精度高等一系列优点,成为飞机噪声测量方面的主要计量equipment.At目前进行的调查使用声级计的传统方式,大多是所有是多点周期survey.Because的,在航空噪音调查过程中,仪??器的位置,等待能够高度影响测量结果的因素很多,而且声级计是无法在调查过程中学习目前的飞机参数和功率条件下,这样不仅提高了测量误差系数,而且使的数据有commeasurability.However的,如果使用大型仪器测量的,不仅要耗费巨大的人力物力,而且费时expense.Based这一点,在了解了解噪音的基础上,同时符合中国民航总局在保证下的噪声测量规定的前提下,无论是通过电脑,使用的GPS实现声级计同步空气飞机噪音映射,并讨论其可行性。
Based on a variety of wetland ecological restoration theory summed from wetland habitats, biology, structure and function of angle for the wetland ecosystem conduct protection and restoration of ways, according to local conditions in accordance with the appropriate wetland protection sequence commenced wetlands protection and restoration, at the same time needConstruction of Plant landscape system through the transformation of wetland plants basal conditions, reasonable plant configuration means the landscape to create a wetland plants. This article through the wetland landscape to create the role, the way the angle of the sort of research at this stage, and summarizes the research related to dynamic domestic and foreign Wetland Park, from the interpretation at this stage about urban wetland park landscape to create a more comprehensive perspective results.
