应对未来城市发展的创森理念与技术 总被引：2，自引：2，他引：0
通过分析未来城市发展需求,提出城市森林是继承与构建城市自然生态系统的主体、是城市绿化的高级阶段的思想;预测未来城市形态,提出以生态绿化空间为主体的未来城市空间"网状结构"以及从绿肺扩展为绿脉的观念和构建生态绿地网络的技术;从城市现阶段发展启动出发,根据实践案例,提出城市"生态-文化区"(ECD)概念以及点、带结合的ECD网络空间技术。

Abstract Although recreational pressure correlates to population size which in turn influences city growth, there is little evidence of how such processes of urban growth have affected the availability of urban fringe forests (forests with good recreational qualities located completely outside and up to 3 km from the city borders). Hence, the aim of this study was to examine consequences of urban growth on urban fringe forest availability in Sweden for the period 2000–2010. An overlay analysis was conducted in a GIS to identify urban fringe forests with good recreational qualities. A selection of Swedish cities with >2000 inhabitants (n = 428) was used along with a regional division to identify trends of cities in forest regions and in other regions. Results showed that the median availability of urban fringe forests had increased in all regions, both in absolute amounts and per 1000 inhabitants. A majority of the cities individually showed increased levels of urban fringe forests, despite contemporary urban growth. Availability had also decreased in about a third of the cities, most notably among those with greater population growth. Increasing populations and a future demand for recreation in proximate forests make further studies relevant, as other processes than urban growth have affected the availability of urban fringe forests. 相似文献

1 INTRODUCTIONUrban greening and urban forestry are the often-usedterms today concerning planning trees and vegetationin a city to benefit the city environment and the citylife. Urban greening is defined as the planning andmanagement of all urban vegetation to create or addvalues to the local community in an urban area(Konijnendijk, et al, 2002). Urban forestry is definedas the art, science and technology of managing treesand forest resources in and around urban communityecosystems for th… 相似文献

INTRODUCTION China is the country with the largest number of people in the world. In the past 20 years, the rapid urbanization proceeding had brought huge pressure on the ecology, environment and economy. The European practice showed that the ecological and environmental problem in the city could be solved by developing Urban Forestry (Konijnendijk 2003; Chai Yixin et al. 2004; Konijnendijk et al. 2005). Additionally, urban forestry policy formulation and management methodologies are t… 相似文献
