Flagstaff Urban Trails System and Its Inspiration for the Construction of China National Trails System

Flagstaff Urban Trails System(FUTS) is a city-wide network of non-motorized, shared-use pathways that are used by bicyclists, walkers, hikers, runners, and other users for both recreation and transportation. FUTS totals 79.2 km in Flagstaff, the Flagstaff government approved the fi rst plan in 1988, and FUTS Trail Priority Evaluation 2011 outlined the evaluation criteria, trail rankings and ranking results The new FUTS Master Plan shows about 130-km planned trails, and creates an ultimate trail system about 210 km. FUTS management organization and Transportation Tax Program is the key to keep the successful works of FUTS. Status quo of China National Trails System(CNTS) is reviewed as: scenic areas have relatively sound trail systems, but there is no any standard system; green corridors within the urban and rural system become popular, but there is no connection system. The development of China National Trails System can be promoted in 3 aspects: establishing national trails system, planning and design trails comprehensively, stressing daily operation and management.

Touristic Ecological Footprint of Jiufeng National Forest Park in Beijing Based on Component Method

This paper,based on the ecological footprint component method,calculated the touristic ecological footprint of Jiufeng National Forest Park in Beijing.The results showed that in 2013,in Jiufeng National Forest Park,the total touristic ecological footprint was 183.08 hm2,the total ecological capacity was 225.16 hm2,the total touristic ecological surplus was 42.07 hm2,and the average touristic ecological surplus was 0.000 4 hm2 per capita,indicating that tourism in Jiufeng National Forest Park was in ecological surplus and ecological security.However,forest parks in Beijing at large were in ecological deficit.This paper suggested that the tourist flow volume of forest parks with a big ecological deficit should be moved to forest parks with an ecological surplus.Besides,forest parks are expected to strengthen the development and management,improve the availability of forest recreation resource,and promote the environmental protection awareness of tourists,so as to boost the sustainable development of forest park tourism.

以2005—2020年中国知网(CNKI)和Web of Science数据库为文献来源,采用文献计量方法对土壤微生物宏基因组学研究现状进行统计分析。结果表明,中外学者采用高通量技术进行土壤微生物宏基因组研究的报道持续增加,研究对象以细菌为主,其次是真菌;研究的生境涉及根际、沉积物等。英文文献的研究机构和作者之间合作紧密,而中文文献的研究机构与作者之间的合作以中科院体系为主。在文献质量方面,以美国学者所发表文献的引用率最高,而中国学者所发文献中引用率排名靠前的文献较少。未来基于高通量测序的土壤微生物宏基因组研究应进一步加强机构与人员合作,注重学科交叉,以创新的思维在基因、功能等不同水平上全面分析了解土壤微生物,以深入挖掘其生态学功能,为生态系统的可持续发展提供服务。     

Political contestation,resource control and conservation in an era of decentralisation at Indonesia's Kerinci Seblat National Park

Since the fall of long‐time strongman Suharto and his authoritarian ‘New Order’ government in 1998, Indonesia has embarked upon a series of decentralisation and democratisation reforms. This new era of decentralised politics has come to be known as Reformasi and has significantly altered the political landscape of the archipelago as national and subnational levels of administration continue to contest the balance of power. Indonesia's national parks, which remain under the authority of the national government, have become arenas for negotiated encounters between local resource users, aspiring district elites and the national government. This essay explores three legacies of incomplete and unfinished decentralisation as they related to national‐park‐based conservation, using Sumatra's Kerinci Seblat National Park as a case study.
