The development of green open spaces is the key component for cities built for the people and a major initiative to enhance the core competitiveness of Chinese cities.This paper summarizes the research on green open spaces in international metropolitan cities,focusing on public participation,funding mix,and governmental actions.It focuses on the alignment of interests between public,private,and community sectors in New York City's green open space development in a series of case studies.It draws lessons from New York's experience and applies them to Chinese cities and proposes that:private non-government organizations should be introduced to improve the mechanism of major development and governance;real estate development incentives should be optimized to guide the private capital to provide public welfare;and policy innovation in land and property development is imperative in fiscal health and sustainability. 展开更多

In order to find the best intercropping pattern of fresh maize and mung bean, five planting patterns, namely fresh maize monocropping, mung bean monocropping, fresh maize and mung bean intercropping at row ratios of 2∶4, 3∶3 and 4∶2 were set up, and the yields and economic benefits of these planting patterns were analyzed. The results showed that the LERs of the three intercropping patterns were all above 1, and the economic benefits of 2∶4, 3∶3 and 4∶2 fresh maize and mung bean intercropping patterns were seen an increase of 2.85%, 17.64% and 14.26% respectively compared with fresh maize monocropping and an increase of 52.06%, 73.92% and 68.93% respectively compared with mung bean monocropping.Among the three intercropping patterns, the intercropping pattern with row ratio 3∶3showed the best effect, which also derived the highest LER with greatest economic benefit. 展开更多

According to the general tendency of the development of enterprise cultural in the 21st century, more and more intense attentions will be paid on the enterprise culture. Thus, while the world green tendency and the green demand rise increasingly, the research on the green cultural management is becoming more important. The study of the green cultural management is not only of vital significance in promoting the continuous development of social economy, but also exchanging the way of the economic growth from extensive pattern to intensive pattern, improving the capacity of the competition and economic benefit of the company, and accelerating the international business. Moreover, the research has another significant importance in enriching and developing the science of enterprise of management. 展开更多

China’s urban expansion,food security,and energy transition are in a critical situation.One solution is to tap into the green production potential of the built urban environment and explore new ways to save land space and alleviate ecological pressure through food and solar energy production.This paper differs from previous ecological compensation studies,which mostly focus on key ecological functional areas or fiscal compensation mechanisms,in that it innovatively establishes an ecological compensation mechanism within the urban space.In this paper,we propose the"green productive area"of cities as a way to measure the ecological carrying capacity improvement potential of cities from the perspective of urban ecology,and it is based on converting the green resource income of cities into the ecological footprint area they could save under the same conditions.First,a typological approach was used to establish a compensation strategy for green production.Second,a spatial inventory was taken of all elements of the built environment and an analysis of their green production potential was carried out.Finally,it was necessary to establish a unified accounting standard for the ecological land saving benefits of different green production options,which could be converted into green productive land area indicators.In the case of Xuefu Street in Nankai District,Tianjin,the available rooftops and idle land were used for green production,which supplemented the ecological carrying capacity provided by the natural land occupied by 12%of the buildings in the district. 展开更多

Metropolitan Manila, the capital region of the Philippines, initiated urban forestry projects toshowcase its environmental benefits. Metro Manila was once a part of a tropical mangrove forest dominatedby small trees locally called nilad (Scyphiphora hydrophyllaceae). The fast-paced urbanization transformedthe original ecosystem into a bustling metropolis subjected to environmental decay. The establishment ofurban forestry is one of the interventions sought by the government to mitigate the environmental conditions.Thus, the concept of participatory urban forestry was formalized in 1988 by the national government.However, it was during the early years of the 1970s that the idea of exerting collective effort in greeningMetro Manila started through the Green Revolution, with the primary motive of uplifting the economiccondition of the people rather than on ecological enhancement. The project was forced on the people to plantvegetables and fruit trees with less emphasis on forest trees species. Although the project was not successful,the government realized that the citizenry could be a great partner for a collective worthwhile undertaking. 展开更多
