本研究以阳江银滩滨海旅游区3种景观小跌水为研究对象,进行微尺度下空气负离子浓度的分布观测。研究周期约为一年,按季度随机选择检测时间,2012年12月至2013年10月期间共检测12次,结果表明:在风速范围为1.1~2.3 m·s-1的情况下,滨海景观小跌水环境空气负离子浓度明显高于旅游区无水体的内路段,且高浓度尺度为以水体为中心半径0~1.5 m 处,1.5 m 之外随距离增加而浓度急剧下降,渐趋底线后缓和持平;小跌水负离子浓度与距离和湿度呈正相关关系,与温度相关性不大。小跌水是园林景观水体中最常用的形式,建议设计应缩短活动场地与水体间距离,增大两者接触面;适当种植遮阴乔木,通过合理的空间流向设计形成有利的风导向,从而最大程度地实现空气负离子对人体的保健效用。
本研究以暘江銀灘濱海旅遊區3種景觀小跌水為研究對象,進行微呎度下空氣負離子濃度的分佈觀測。研究週期約為一年,按季度隨機選擇檢測時間,2012年12月至2013年10月期間共檢測12次,結果錶明:在風速範圍為1.1~2.3 m·s-1的情況下,濱海景觀小跌水環境空氣負離子濃度明顯高于旅遊區無水體的內路段,且高濃度呎度為以水體為中心半徑0~1.5 m 處,1.5 m 之外隨距離增加而濃度急劇下降,漸趨底線後緩和持平;小跌水負離子濃度與距離和濕度呈正相關關繫,與溫度相關性不大。小跌水是園林景觀水體中最常用的形式,建議設計應縮短活動場地與水體間距離,增大兩者接觸麵;適噹種植遮陰喬木,通過閤理的空間流嚮設計形成有利的風導嚮,從而最大程度地實現空氣負離子對人體的保健效用。

Distribution of microscale negative air ion concentration of three kinds of landscape dropping waterscape,in coastal tourist area of Yangjiang were investigated in this paper.The surveys were randomly conducted every quarter from December 2012 to October 2013, we carried out twelve experiments. Experimental results showed that, as wind speed was 1.1 m/s ~2.3 m/s, ,the negative air ion concentration of three landscape dropping waterscape were significantly higher than negative air ion concentration of tourist area road., high concentrations were determined in water body centered radius within 1.5 m, when distance is more than 1.5 m,concentrations sharply fell with increase of distance, till stable near bottom line; Aeroanion concentrations of small dropping waterscape was positively correlated with distance and humidity, little correlation with temperature. dropping waterscape is the most commonly form used in landscape design.It is concluded that distance between activity field and water body should be shorted, with two contact surfaces increased, appropriate planting shade trees is good for achieving favorable wind direction, so as to maximize realization of negative air ions to human body health benefits.
