摘要
利用河北太行山区东高昌村2016-2019年土地流转数据,运用ESL(energy system language)模型对河北太行山区土地流转前后过程进行模拟评价,基于土地利用情景和劳动力投入视角进一步模拟了土地流转后系统能量变动情况.结果表明:1)土地流转后农作物生物量、资本及生态环境相比土地流转前均有显著提升.10年后农作物生物量、资本和林地生物量分别达到土地流转前的12.97、2.10、36.54倍;50年后农作物生物量、资本和林地生物量分别达到土地流转前的15.34、4.23、39.22倍;100年后农作物生物量、资本和林地生物量分别达到土地流转前的26.79、7.39、66.60倍.2)改变种植结构的流转效果一般,但调整劳动力投入结构使土地流转后的南瓜生物量和资本呈现倒"U"形变化趋势,南瓜生物量在24年达到峰值,资本在48年达到峰值.投入当地劳动力使农作物生物量提高46.5％,资本提高212％,效果最为显著.
Abstract
Land transfer data at Donggaochang Village in the Taihang Mountains region of Hebei province from 2016 to 2019 were subject to analysis by the ESL(energy system language)model,to simulate and evaluate changes in system energy after land transfer,with attention to land use scenarios and labor inputs.Crop biomass,capital and ecological environment were significantly increased after land transfer.Ten years after land transfer,crop biomass,capital and forest biomass were 12.97 times,2.10 times and 36.54 times higher respectively than before.Fifty years later,crop biomass,capital and forest biomass increased to 15.34 times,4.23 times and 39.22 times respectively of these parameters before land transfer.After 100 years,these parameters increased to 26.79,7.39 and 66.60 times of before.Effect of land transfer on planting structure was average,but effect of adjusted labor input structure on pumpkin biomass and capital after land transfer showed an inverted U-shape.Pumpkin biomass reached a peak in 24 years,capital reached a peak in 48 years.Local labor input increased crop biomass by 46.5％,capital by 212％.
