摘要:
土地利用变化是影响陆地生态系统碳储量变化的重要驱动因素。引入了生态系统服务对土地利用变化脆弱性评估方法，以黑龙港流域巨鹿县为例，在分析巨鹿县2000-2015年土地利用与强度变化规律的基础上，研究区域土地利用变化对碳储量的影响。结果表明：2000-2005年这一时间段内，研究区内耕地、建设用地面积不断减少而未利用地的面积反而处于增加的态势，造成碳损失加快，致使生态系统碳储量对土地利用强度变化表现得愈加脆弱，土地利用强度指数每增加一个单位，植被、土壤、总碳储量分别减少36.66万t，1.03万t，37.67万t。在2005-2010年和2010-2015年这两个时段内，随着政府合理的进行土地利用调控，土地利用强度指数每增加一个单位，生态系统总碳储量分别增加1.24万t和1.06万t，不断表现出正向的潜在影响，碳汇也在不断增加，那么合理的调整土地利用结构、加强规划管理将会成为降低生态系统碳储量对土地利用变化脆弱性的关键。
Abstract:
Land use change is an important driver of carbon storage in terrestrial ecosystem. Therefore, we introduce the ecosystem services-based land use change vulnerability assessment method to study the effects of land use change on carbon storage and evaluation based on land use change and carbon storage in Heilonggang basin in Julu County, to analyze land use and intensity changes of Julu County in the period from 2000 to 2015, and to study the regional carbon storage changes in vegetation and soil. The results showed that:(1) from 2000-2005, the study area of cultivated land, construction land and unused land area decreased continuously in the area but the unused land area increased, causing the acceleration of carbon loss, and resulting in vulnerability of ecosystem carbon storage in response to land use intensity changes, every increase of land use intensity index a unit of vegetation, soil, total carbon reserves reduced by 366.6 thousand tons of C, 10.3 thousand tons of C and 376.7 thousand tons of C; (2) from 2005 to 2010 and from 2010 to 2015, with the government’s rational land use regulation, each increase of land use intensity index of a unit, the total ecosystem carbon reserve increased by 12.4 thousand tons of C and 10.6 thousand tons of C, continued to show the potential positive effect, carbon sequestration is also increasing, so the reasonable adjustment of land use structure, strengthening planning and management will be reduced key vulnerability of ecosystem carbon storage to land use change.
