The results show that the forest vegetation potential productivity in most areas of Fujian is large,and decreases gradually form the coastland to the inland ;the highest values are in Pinghe.
结果表明:福建省森林植被潜在生产力较大,因而,提高作物产量的潜力还很大;除局部地区外,植被潜在生产力沿海高,内陆低;沿海的平和、云霄等地气候生产力高,而内陆的屏南、周宁、寿宁等地气候生产力低。
According to climate data and forest resource data,the forest potential productivity of Linkou forestry bureau in Heilongjiang Province was calculated by using Miami model and Thornthwaite Memorial model.
依据气象资料及森林资源数据,利用Miami模型和Thornthwaite Memorial模型,对黑龙江省林口林业局的森林潜在生产力进行估算,得出了潜在生产力与温度和降水量的关系,并对林口林业局森林实际生产力进行了评价。
