“…System dynamics is an integrated simulation and prediction model, the greatest advantage of which is that it can avoid the one-sidedness of low-dimensional and single predictions and is suitable for dealing with non-linear and long-term problems of more complex systems. It has been widely used in the study and management of energy consumption, greenhouse gas emissions, and environmental management at different scales, including the national, regional, and industrial scales [38][39][40].…”

The Hu-Bao-O-Yu urban agglomeration is an important energy exporting and high-end chemical base in China, and is an important source of carbon emissions in China. The early achievement of peak carbon emissions in this region is particularly crucial to achieving the national carbon emission reduction targets. However, there is a lack of multi-factor system dynamics analysis of resource-dependent urban agglomerations in Northwest China, as most studies have focused on single or static aspects of developed urban agglomerations. This paper analyses the relationship between carbon emissions and their influencing factors, constructs a carbon emission system dynamics model for the Hu-Bao-O-Yu urban agglomeration, and sets up different single regulation and comprehensive regulation scenarios to simulate and predict the carbon peak time, peak value, and emission reduction potential of each city and urban agglomeration under different scenarios. The results show that: (1) Hohhot and Baotou are expected to reach peak carbon by 2033 and 2031 respectively, under the baseline scenario, while other regions and the urban agglomeration will not be able to reach peak carbon by 2035. (2) Under single regulation scenarios, the effect of factors other than the energy consumption varies across cities, but the energy consumption and environmental protection input are the main factors affecting carbon emissions in the urban agglomeration. (3) A combination of the economic growth, industrial structure, energy policy, environmental protection, and technology investment is the best measure to achieve carbon peaking and enhance the carbon emission reduction in each region as soon as possible. In the future, we need to coordinate the economic development, energy structure optimisation and transformation, low-carbon transformation of industry, strengthen research on carbon sequestration technology, and further increase the investment in environmental protection to make the Hu-Bao-O-Yu urban agglomeration a resource-saving urban agglomeration with an optimal emission reduction.

“…Study on species composition and stand structure has been frequently used in assessing restoration (Gunawan et al, 2011), monitoring (Palace et al, 2016;Feldmann et al, 2020;Ramli et al, 2022), and evaluation of degraded natural forest conditions (Gunawan et al, 2011;Marvin et al, 2014;Kituyi, et al, 2018;Segura et al, 2021), and in obtaining information on changes in a forest area due to natural and human-related disturbances (Mawazin & Subiakto, 2013;Nopiansyah et al, 2016;Fischer et al, 2016;Gebeyahu et al, 2019;Pamoengkas et al, 2019;Feldmann et al, 2020;Siti Nurfaeiza et al, 2022;Larocque, 2022;Liang et al, 2022;Zhang et al, 2022), species diversity (Gunawan et al 2011;Soendjoto et al, 2014;Gebeyahu et al, 2019;Segura et al, 2021;Ahmad Fitri et al, 2022;Rohaiza et al, 2022), protected threatened and economic species (Murdjoko et al, 2016;Niningsih et al, 2017;Gebeyahu et al, 2019), and plant communities (Gebeyahu et al, 2019). However, studies of the effects of gap planting implementation to rehabilitate degraded tropical natural forest on its species composition and stand structure remain scarce.…”

By 2020, there were 33.4 million ha of degraded forests in Indonesia. If it is not rehabilitated, there will be land-use changes that significantly affect its biodiversity and environment. Gap opening and planting is an important silvicultural regeneration method to rehabilitate degraded tropical natural forests. We studied the subject in a 10 ha degraded lowland tropical natural forest in Central Borneo, Indonesia. The study aims to compare the composition and structure of degraded tropical natural forests before and after gap opening and planting. The methods used consist of 1) gap opening and planting with a proportion of the total gap area to the total degraded natural forest area of 40%; 2) vegetation analysis to assess the composition and structure of forest. The results showed that the gap opening and planting activities led to a decrease in the density of seedlings, saplings, poles, and trees, and cause loss of two species at seedling level and one species at sapling level. The analysis results of the stand structure and species composition, index of species diversity, species evenness index, and community similarity index before and after gap opening and planting of the degraded forest in the study area of 10 ha showed that there is no changes of these variables. These results showed that the use of the gap opening and planting method in the rehabilitation of degraded forests is able to maintain the stability of species composition and stand structure, species diversity, species evenness, and forest communities. In conclusion, the study provided significant empirical results on the composition and structure of degraded tropical natural forests before and after gap opening and planting, which would be instrumental for the development of rehabilitation strategies. It is recommended that the rehabilitation of degraded tropical natural forests in Indonesia can be carried out using the gap opening and planting method.
