摘要:

运用能值方法分析农牧交错带内乌兰察布市2011—2020年生态经济系统可持续发展状况,以确定区域开发合理规模,实现区域可持续发展。结果表明:2011—2020年乌兰察布市生态经济系统投入能值(F)平稳上升;产出能值(Y)不断减少;环境负载率(ELR)不断上升;10 a间能值可持续指标(ESI)出现较大波动,总体下降。2011—2016年乌兰察布市能值可持续发展指标高于1,生态经济系统发展是可持续的;2017—2020年低于1,为不可持续状态。因此,中短期需增加可更新资源投入,缓解不可更新资源过度使用带来的生态环境退化、环境负荷高等问题,产业上进行技术创新降低生产成本,提高生产效率推动高能值产品产出,寻求新兴高能值产出部门替代低能值产出部门;长期需提高区域人口自然增长率,以便提高区域能值需求和产出。以优势交通区位和丰富的资源承接周围相对发达地区能值产出率高和环境负载率低的产业部门,以增强区域可持续发展能力。

Abstract:

The emergy method was used to analyze the sustainable development status of the ecological and economic system in Ulanqab City in the agro-pastoral ecotone from 2011 to 2020, in order to determine the reasonable scale of regional development and achieve regional sustainable development. The results show that: from 2011 to 2020, the input emergy (F) of Ulanqab City’s ecological-economic system increased steadily; the output emergy (Y) continued to decrease; the environmental load rate (ELR) continued to increase; the emergy was sustainable for 10 years The indicator (ESI) experienced large fluctuations and declined overall. From 2011 to 2016, the emergy sustainable development index of Ulanqab City was higher than 1, indicating that the development of the ecological-economic system was sustainable. From 2017 to 2020, the emergy sustainable development index was lower than 1, indicating an unsustainable state. Therefore, in the short and medium term, it is necessary to increase investment in renewable resources to alleviate the ecological environment degradation and high environmental load caused by the overuse of non-renewable resources. The industry should carry out technological innovation to reduce production costs, improve production efficiency, promote the output of high-emergy value products, and seek new emerging technologies. High-emergy value output sectors replace low-emergy value output sectors; the natural growth rate of regional population needs to be increased in the long term in order to increase regional emergy demand and output. With advantageous transportation location and abundant resources, we will undertake industrial sectors with high emergy output rates and low environmental load rates in surrounding relatively developed areas to enhance regional sustainable development capabilities.
