Response of Ecosystem Carbon Fixation Value to Forest System Structure in Yulin City
-
摘要:
将生态资源纳入经济体系统筹管理是环境可持续发展的必然要求。对于生态脆弱地区，加强环境压力变化下的资源管理尤为重要。笔者从系统结构的角度理解生态系统固碳功能变化特征，在榆林地区结合景观结构指数对固碳功能进行空间分析。2000～2020年榆林市生态系统固碳服务价值持续增加，2000～2010年增长较快，2010～2020年增速减缓。在空间分布方面，单位面积固碳价值从东南向西北递减，东南部的增长速率也更快。工业活动是形成榆林市生态系统固碳价值西北、东南分划的主要因素，东南部区县受生态系统结构变化的影响更强。研究结果表明，在生态脆弱区实施生态建设和修复工程时，应综合考虑生态系统的结构性以提高地区生态系统潜在的功能性。
Abstract:It is an inevitable requirement of environmentally sustainable development to bring ecological resources into the overall management of the economic system. For ecologically fragile areas, it is particularly important to strengthen resource management under changing environmental pressures. This paper attempts to understand the change characteristics of carbon fixation function of ecosystem from the perspective of system structure, and carries out spatial analysis of carbon fixation function in Yulin area combined with landscape structure index. From 2000 to 2020, the carbon sequestration service value of Yulin’s ecosystem continued to increase, and the growth rate was fast in 2000～2010 and slowed down in 2010～2020. In terms of spatial distribution, the carbon sequestration value per unit area s decreases from southeast to northwest, and the growth rate in southeast is also faster. Industrial activities are the main factor to form the northwest and southeast division of carbon sequestration value of Yulin, and the southeast counties are more affected by the change of ecosystem structure. The results of the study suggest that we should comprehensively consider the structure of the ecosystem to improve the potential functionality of the regional ecosystem when implementing ecological construction and restoration projects in the ecological fragile areas in the future.
