福建省植被气候生产力的时空分布特征

Spatial-temporal distribution characters of climatic productivity of vegetation in Fujian Province

估算了福建省近30年来的植被气候生产力,结果表明,福建省植被气候生产力从东南部沿海向西北方向逐渐降低。全省植被气候生产力的高值区域主要集中在东南沿海部分,大部分县市在16000 kg.hm-2.a-1以上;西部和北部的山区植被气候生产力值较低,大部分在10000-15000 kg.hm-2.a-1之间。近30年来福建省植被气候生产力有逐渐提高的趋势,全省植被气候生产力以20世纪80年代最低,21世纪初期几年最高,相差1407 kg.hm-2.a-1。

The values of climatic productivity of vegetation in Fujian Province are estimated, and their distribution characters are analyzed. The highest value of climatic productivity of vegetation is in the marine southeast of Fujian province, then becomes lower to the northwest. The high values of climatic productivity of vegetation in the marine southeast of Fujian Province are more than 16000 kg · hm^-2 · a^-1 in the most counties, but in the mountain regions of north and west are low, most 10000 - 15000 kg · hm^-2 · a^-1 In the recent 30 years, the values of climatic productivity of vegetation of Fujian Province has tended to be higher, the lowest value is in 1980s, and the highest value is in the first years of 21 century, the distinction is 1407 kg · hm^-2 · a^-1 between them.
