福建省森林植被潜在生产力的估算及其分析

Evaluation and Analysis of Forest Vegetation Potential Productivity In Fujian Province

应用Lieth—Box模型,结合主要气象因子(降水量、气温等)资料分别计算了福建省森林植被的可能净第一性生产力、谷物产量和木材产量.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.表1,参11.

According to Lieth -Box model ,the net primary productivity, the outputs of cereals and wood in Fujian province are assessed using the data of annual temperature,rainfall and evaporation. 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. Yunxiao and Nanjing counties in the coastland ,on the contrary,the lowest in Pingnan,Zhouning and Shouning counties of the inland.
