摘要:

以6期(1985年、1990年、1995年、2000年、2005年和2008年)土地利用数据和1984~2008年的粮食产量数据为基础,对冀中南地区农田生物生产力和碳截获能力进行了估算,并对其时空差异特征及其影响因素进行了分析。结果表明:自20世纪80年以来,冀中南地区农田中生物生产力和碳截获能力表现为增强趋势,总生物量和碳截获总量分别达到0.065 Pg 和0.025 Pg。农田的碳截获能力具有空间差异性。山前平原地区农田的生物生产力和碳截获能力均比较大,而在西部山区和东部低平原区表现较低。随着农田生物生产力和碳截获能力的增强,加速了碳循环和碳汇的过程。虽然农田碳截获总量很大,而且只是动态的碳库,但是如果能够合理利用必将增加农田的实际固碳能力。

Abstract:

Based on six period of land-use data (1985, 1990, 1995, 2000, 2005 and 2008) and grain yield data(1984-2008), biological productivity and carbon capture capability of crops in the mid-south parts of Hebei Province were estimated. Meanwhile, the spatial-temporal change of biomass and carbon capture capability were analyzed. The result showed that: biological productivity and carbon capture capability appeared increasing trend from 1980s. The total biomass and carbon capture reached 0.065 Pg and 0.025 Pg, respectively. Moreover, crops capture capability showed spatial variability. Biological productivity and carbon capture capabilities in the piedmont farmland are much larger than the western mountains and lower plains areas. On the other hand, with the increase of biological productivity and carbon capture capabilities, the carbon cycle and sequestration process were accelerated. Though the farmland is only a dynamic carbon pool, by the large quantity of carbon capture, the carbon sequestration capacity will increase with the reasonable use.

Key words: grain, carbon sequestration, biomass, harvest index
