浅析城市发展对太阳辐射的影响

由于城市的发展，大气中污染物增加，使得城市全所的太阳辐射发生变化，以福建为例，直接辐射出现全年多数月及年总量递减趋势，且由东南沿海经济发展快地区向内地经济发展慢地区递减速率减慢。总辐射多数月及年总量随城市发展呈递减趋势。混浊因子则多呈增加趋势，诸多变化趋势均与人口变化呈密切相关关系，说明辐射值的变化与城市发展密切相关。

ANALYSIS ON THE EFFECT OFURBAN DEVELOPMENT ON SOLAR RADIATION

The variations of solar radiation are caused by urban developrnent and air pollution in urban areas.Most of monthly direct solar radiations in a year and annual direct solar radiations decrease with years in urban areas of Fujian Province.And the greater urban ecomomic developments,the greater decrease of direct solar radiation from southeastern coastal areas to inland areas in Fujian Province.Most of monthly global radiations in a year and annual global radiations also decrease in urban areas.But the turbidities increase with years in urban areas.And the variations of solar radiations and turbidities have correlations with urban populations in Fujian Province.
