龙胜各族自治县空气负离子资源的分布特征及开发策略

Distribution characteristics and exploitation strategy of aero anion resources in Longsheng county

运用AIC-1000型空气负离子浓度仪对龙胜各族自治县(以下简称龙胜县)空气负离子资源进行实地观测,通过反距离加权插值的方法模拟县域空气负离子资源的空间分布.研究结果表明:1)龙胜县各监测点位的空气负离子平均浓度为4 265个/cm3,县域空气非常清新,适宜开展空气负离子健康旅游;2)龙胜县空气负离子浓度北部高于南部,人口稀疏区高于人口密集区,森林覆盖区域高于其他植被覆盖区域,瀑布、溪流等动态水集中的区域普遍较高.根据上述研究结果,对龙胜县空气负离子资源开发提出以下建议:1)在保护好森林和水体资源的基础上,宣传空气负离子的保健功效;2)依据空气负离子的空间分布规律合理划分功能区以充分发掘空气负离子资源的价值;3)在空气负离子低浓度区合理配置绿地面积、营造水体景观;4)定期发布空气负离子浓度,实现空气负离子资源的动态监测.

Using the AIC - 1000 air negative ion concentration tester, we made field the aero anion resources in Longsheng county and simulated the spatial distributior distance weighting interpolation method. The results show that the average concentrations at all the monitoring sites in the county is 4 265 per cubic centimeter observations of by the of aero inverse anion ,and the county is suitable to develop aero anion healthy tourism. The aero anion resources distribute in the county as follows. The concentration of the aero anion in the north is generally higher than in the south. The concentration in sparsely populated area is much higher than in the densely populated areas. The concentration in forest area is much higher than in other vegetation covering area; and the concentration in the region with waterfalls, streams, and other dynamic water is generally high. Based on the above results, we suggest that the local government exploit the aero anion resources in Longsheng county as follows： 1 ） protecting the forests and the water resources and propagating the health benefits of aero anion, 2） dividing the functional areas rationally based on the spatial distribution of aero anion in order to fully exploit the aero anion resources,3） allocating the green space rationally and constructing water landscape in the area with low concentration, and 4） establishing an announcing system of aero anion concentration to realize the dynamic monitoring of the aero anion.
