An urban agriculture park (UAP) is a mixture of various kinds of urban agriculture and has a group of administrators to plan and manage its landscapes. Thus, the relationships between users and the ability of the UAPs to provide services are crucial. This study investigated the user profiles of three kinds of UAPs in Beijing, China. Investigation of 345 interviewees suggested that most of the users have an upper-middle level income and are well educated. Social connections vary across different types of UAPs. An assessment matrix of landscape services was introduced for a pioneer of UAP, Little Donkey Farm, based on questionnaires, a field survey, and indicators of landscape patterns. Pearson correlations between service demands and users’ characters showed age, companions, and education level were significantly correlated to the needs of scenery and education services. The landscape with the highest supply value was the vegetable plots planted by members. The scenery service was not adequately supplied, and 31.5% of the areas did not meet the demand. Based on the budgets of supply and demand, six types of landscape should be optimized. This study provides an approach to understand the path of landscape service provision in UAP and supports basic knowledge on how to better involve urban agriculture in sustainable development.

The power exchange mode is widely applied in the rental field as an efficient energy supply method for new energy vehicles. The power supply-demand relationship analysis swaps. In particular, the quantitative spatial analysis of sub-regions is of great significance for optimizing the spatial layout of power swapping stations, better operation of taxis, and more efficient power swapping stations. Therefore, this paper analyzes the correlation between the ten states of taxis and the corresponding power exchange. The present analysis targets the limitations in the existing methods to analyze the power exchange supply and demand and utilizing the big data pertaining to real-time taxi operation, order-taking mode, and station-swapping operation. As per the correlations, a calculation method is established to determine the power exchange demand based on the location where the orders are received and the matching method of the power exchange supply and demand. Besides verifying the scientific nature and feasibility of the method empirically, this study also ensured its great flexibility, which allows it to adapt to more complicated social scenarios. The big data analysis indicates that determining the spatial distribution of demand based on the location from where the taxi orders are received is far more rational and practical. Thus, this study has a vital role in guiding the location and layout of interchange stations.

For the most part, research and policymaking on urban gardening have focused on community gardens, whether in parks, vacant lots, or other public land. This emphasis, while important for many Midwestern cities, can obscure the significance of privately owned land such as front yard and back yard and their crucial connections with gardening on public land. In this case study, we examine how policies and practices related to gardening and the management of green space in two Midwestern cities exceed narrow visions of urban agriculture. The article explores the cultivation of vacant lot gardens and private yards as two modes of property in similar Midwestern contexts and argues that the management of green space is about more than urban agriculture. Instead, we show how urban gardening occurs across public/private property distinctions and involves a broader set of actors than those typically included in sustainability policies. Gardening also provides a key set of connections through which neighbors understand and practice sustainability in Midwestern cities.
