As the earliest discussed concept of Green Infrastructure (GI), Landscape-scale GI, in the form of an ecological network capable of balancing development and conservation, has received widespread attention. Its multifunctionality is one of the important features. However, the lack of information and funding, weakness of management authority and technical support make the practice of Landscape-scale GI challenging. Compared to GI adapted in stormwater management, which has comprehensive guidance from theory to practical technologies by officials during its introduction and promotion in other countries, Landscape-scale GI, despite a rich theoretical research foundation, is often overlooked due to insufficient summary research on practical techniques. To address this gap, this study uses mixed methods research to comprehensively analyze 27 Landscape-scale GI practical projects led by the Conservation Fund over the past 20 years to explore patterns in their technical applications. Through qualitative analysis, we standardized and classified descriptive information for these 27 projects and, combined with statistical analysis, clarified the practice development trends committed to balancing development and conservation. The quantitative analysis concentrated on the corresponding relationships between technical applications and project objectives, and GI functions. Based on this, the study categorized the technologies used, summarizing core technologies applicable to most Landscape-scale GI practices, providing some support for the promotion of Landscape-scale GI.

<jats:p>Community gardens offer broad research opportunities and analytical resources encompassing urban planning to environmental sustainability, food systems, and social capital. However, little is known about the knowledge structure and research development related to community gardens. This study presents an in-depth bibliometric performance analysis and visual scientific mapping analysis of the literature on community gardens by examining 487 published papers selected from the Web of Science database. The results indicated a considerable rise in research papers in this subject area from 2012 onwards, with most contributions from the United States. Studies from high-income countries accounted for 93.22%, and 38 countries have cooperated 167 times in this field. “Health” is the most frequent keyword, and the terms “ecosystem services” has been gaining popularity over the last five years. A combination of co-citation clustering and keyword co-occurrence clustering analysis identified three major research themes in the field of community gardens: “ecosystem services and disservices”, “multidimensional association”, and “sustainable garden systems”. The development of ecosystem value assessment frameworks, the establishment of region-wide soil monitoring databases, accounting for the cost-effectiveness of nature-based solutions, the integration of garden systems into smart cities, and the integration of water management into regulation will be important future research directions regarding community gardens. Overall, this study provides scholars with a systematic and quantitative understanding of community gardens.</jats:p>
