基于系统动力学的建筑废弃物碳排放环境效益研究

为研究不同影响因素下产生的环境效益问题,根据系统动力学理论构建建筑废弃物碳排放管理模型,以碳排放量为主要环境效益指标,基于Vensim软件进行模拟评价,动态分析建筑废弃物碳排放管理模型对环境效益产生的影响。通过对案例进行情景分析,识别影响建筑废弃物碳排放管理模型环境效益的主要因素,并依靠多因素分析方法,梳理总结各因素在管理中的作用效果。结果表明:在多重影响因素作用下,建筑废弃物碳排放单一管理效果有限,当多种因素共同作用于建筑废弃物的碳排放管理时,可有效减少碳排放量,显著提升建筑废弃物碳排放管理效果,可为相关部门的实际操作提供参考。

Rural Carbon Emissions Based on Community Management

Rural community is an effective way to simultaneously achieve manage- ment of ecological resources and protection of natural resources, depending on its management mode based on cooperation, motivation, local experiences and extensi- ble boundary. In the research, carbon emission in community is a kind of ecological resources and negative externality is the cause of increase of rural carbon emission. Compared with governmental ruling and marketing approach, community manage- ment mode proves more effective to solve the problem of negative externality of carbon emission in community. Furthermore, rural carbon, emission was analyzed in detail on basis of community management mode and extending mode of carbon emis- sion in rural areas. In addition, some policies and suggestions were proposed to im- prove community management of carbon emission in rural areas, providing an ef- fective way for low-carbon economy in rural areas.
