Study on Road Greening in the Main Urban Area of Chongqing City Based on Plant Diversity

The greening situation of 242 road greenbelts in 7 administrative regions in the main urban city of Chongqing City was investigated by field survey, and the plant composition, application frequency, species richness and diversity of plants used for road greening in the main urban area were analyzed. The results show that there were 105 species of plants used for road greening(not including seasonal flowers displayed temporarily) in the main urban area of Chongqing City, belonging to 80 genera, 47 families. Among them, there were 95 species of woody plants and 10 species of perennial herbs, accounting for 90.47% and 9.53% of the total number respectively. Some suggestions were put forward according to the current situation and problems of road greening in the main urban area of Chongqing City.

Diversity and Application of Herbaceous Flowers in Urban Road Greening in Hefei City

In urban road greening,the planting of ground cover flowers is essential,and herbaceous flowers are an important part.Through the investigation on the diversity of herbaceous flowers in urban road green spaces of Hefei City,the types,colors,application frequency and planting of herbaceous flowers in urban road green spaces were statistically analyzed,and the application forms of herbaceous flowers in the road greening of Hefei City were studied.The characteristics and problems of herbaceous flowers in the road greening of Hefei City were found,and some development suggestions were put forward.

Spatio-temporal Pattern of Ecosystem Pressure in Countries Along the Belt and Road: Combining Remote Sensing Data and Statistical Data

Building a Green Silk Road by integrating the Sustainable Development Goals(SDGs) is one of the Belt and Road Initiative(BRI) visions, but the BRI faces enormous challenge that is the conflict between economic development and ecological sustainability.Understanding the current scale and trend of the impact of human activities on the ecosystem is the preliminary work to ensure that human activities do not exceed the ecological carrying capacity under the BRI. This study evaluated the ecosystem pressure in countries along the Belt and Road(B&R) from 2000–2017 based on the supply-consumption balance relationship of ecological resources. Net primary productivity(NPP) is taken as the measure of ecological resources, and the supply level and consumption intensity of ecological resources is estimated based on remote sensing data and statistical data, respectively. Results show that thirteen countries with overconsumed ecological resources concentrated in the West Asia/Middle East. Although the intensity of the ecological resource consumption correlated with ecological resource endowments, the ecosystem pressure was determined by social development dependence on the ecological resources at the same ecological resource endowments level. Nearly 80% of countries along the B&R suffered from significantly increased(P < 0.05) ecosystem pressure during 2000–2017, since most of the countries along the B&R were developing countries,and their economic development was highly dependent on ecological resources. Some West Asia/Middle East countries successfully mitigated the ecosystem pressure by importing feed for livestock. Likewise, the Southeast Asian islands benefitted from the import of agricultural products. The results highlight that the BRI should reduce the dependence of social development demands on local ecological resources by international trade for ensuring the increasing ecosystem pressure trend within the ecological carrying capacity.

China's renewed perception of global environmental governance

China's idea of a community of a shared future for humanity(CSFH)has become the guiding principle and norm to be further embedded and integrated into the country's approach to environmental governance.Under the Paris Agreement and the UN Sustainable Development Goals,China strongly emphasizes the implementation of its national strategy to mitigate the global climate crisis,and construct international environmental institutions by advocating fair cooperation resulting in mutual gain.China's role as a responsible major country is expected to be more proactive in international process.In particular,the concept of CSFH exerts positive,far-reaching impacts on the greening of the Belt and Road Initiative and the construction of solid South-South relations.Based on the renewed perception,China shall undertake its responsibilities in the reform of the global environmental governance system by leading multilateralism to strengthen the capacity of relevant international institutions such as the UN.Driven by China's political will,this concept reflects China's more confident attitude toward global environmental governance.Most profoundly,mainstreaming the vision of CSFH will elevate China's role to a new level in the coming years in terms of norm creation in international environmental institutions.

Research on Micro Technology of Microclimate Environment in Urban Green Space Based on Humanization Concept

To create a comfortable microclimate environment,the design methods of green layout and green structure of four common forms of urban green space(park green space,road green space,waterfront open green space,and green space between houses)were discussed,and the modes"concentric three rings"and"three-layer sandwich cake",as well as the matching principles of three-dimensional green elements of trees and shrubs with lawn and hard matrix elements,were proposed.

Strategic Importance of China’s Foreign Aid for Environmental Protection

E nvironm ental protection effo rts are a key aspect of developmental aid which,in turn,is a crucial means to globally promote environmental governance.In recent years,China’s foreign aid initiatives for environm ental protection have developed rapidly,evolving into an integral part of international development aid due to its strategic significance.The establishment of the Green Belt and Road provided China with a rare opportunity to implement its plans for environmental protection aid.Under the Green Belt and Road,China has continuously improved systemic design and actively used non-governmental means to innovate aid models,thus substantially contributing to the environmental progress of aid recipients.Additionally,China’s outreach has significantly improved its international image,built on its soft power,and played a visible and positive role in expanding the international environmental protection market and promoting green development.
