摘要
根据实测的太阳总辐射在全波段的辐射照度Q(Wm-2)估算出光合有效辐射照度UPAR(μmolm-2S-1),利用各类植物的排放因子,估算出大连地区生态植被所排放的VOC,结果表明,生态植被所排放VOC的日变化规律即与植物本身有关又与气温和太阳辐射有关,区域内年排放VOC的总量为256.5t。
The amount of vegetation VOC emission is estimated in Dalian area using different vegetation emission factors and the data of photomorphgenetically active radiation, which derive from total solar radiation. The results show that the vegetation VOC emission is related with temperature, radiation and vegetation species during a whole day. The amount of vegetation VOC emission in Dalian area is more than 256. 5 ton yearly.
