基于交通噪声污染防治的夹心地判定及管理对策

基于土地管理的角度,根据夹心地的定义,归纳得出夹心地具有空间包夹、面积狭小、功能受限和权属独立的特征;基于夹心地的交通噪声污染特征,提出受到交通噪声影响的夹心地的定义和判定方法。当采取噪声防治措施后,两条交通干线之间区域的室外声级无法满足声环境功能标准且噪声敏感建筑室内声级无法满足使用功能要求时,判定该区域为受到交通噪声影响的夹心地。建议通过控制夹心地规模、调整夹心地功能、强化噪声治理措施、完善夹心地管理政策等措施防治夹心地交通噪声污染。

Determination and Management Measures of Sandwiched Zone based on the Prevention and Control of Traffic Noise Pollution

Based on land management,according to the definition of sandwiched zone,sandwiched zone has the characteristics of space inclusion,small area,limited function and independent ownership;Based on the characteristics of traffic noise pollution of sandwiched zone,the definition and judgment method of sandwiched zone affected by traffic noise are proposed.When neither of the outdoor and indoor noise levels met the standards after taking noise control measures,the zone between two traffic trunk lines is judged to be a sandwiched zone affected by traffic noise.It is recommended to prevent and control traffic noise pollution of the sandwiched zone by controlling the scale,strengthening noise control measures,adjusting the functions,and improving the management policies.
