宁德市城市公园绿地系统景观格局分析 总被引:1,自引:0,他引:1
利用QuickBird高分辨率卫星影像图并结合GIS软件,运用景观生态学的原理和方法,分析了宁德市区公园绿地的景观结构和格局.结果表明:宁德市城市公园绿地斑块的形状指数较小,均低于2.5.从不同公园景观类型的破碎度来看,市区级公园景观破碎化最低,仅为0.006 80,而专类公园、街旁公园斑块破碎化程度处于相对较高水平.各类公园绿地景观的分维数普遍较低,均小于1.25,斑块形状相对规则,绿地景观斑块边界较为简单.这种布局不利于维护城市生物多样性,同时也不利于营造自然化绿地景观.所以,今后宁德市在公园绿地建设中,应重点加大社区公园、街旁绿地公园绿地建设力度,提高广场、社区公园、街旁绿地和带状公园的比例,力求各类斑块配置合理,满足当地居民生活休闲需求和绿地生态功能需求. 相似文献

在许多城市,尤其是老城区,社区公园绿地明显已无法满足居民的需求。在某些建成的社区公园,也由于设计欠佳而难以得到充分利用。作者以参与规划设计的重庆渝北龙塔公园为例,从"合理的空间划分,完整的空间序列,适宜的空间尺度"及"道路、水体、地形、植物、小品设施"等环境要素方面介绍了该社区公园的设计手法。 相似文献

小流域治理的景观规划原则与方法 总被引:2,自引:0,他引:2
景观生态学的设计观点虽然尚未被广泛地推广应用于小流域治理实践,但在小流域治理规划中引入景观理念必然成为今后的主流趋势。小流域景观生态规划应遵循因地制宜综合治理的水土保持原则、景观多样性原则与稳定性原则等,规划方法主要包括斑块法、廊道法等5种,小流域景观生态包括农业生态景观、林业生态景观等诸多形式。建议加强景观小流域评价标准研究,以便应用景观生态学理论管理小流域,把水土保持生态工程建设同人文创造有机结合起来,使小流域的生态重建与经济发展更为和谐统一。 相似文献

大都市郊区山地景观规划的案例研究 总被引:3,自引:0,他引:3
都市郊区的山地景观规划旨在协调都市和郊区、景观和发展等之间的利用与保护关系,为当地社区居民抉择产业行为与景观效应保护时,提供一条良好均衡的便捷路径。基于景观协调理念,使用土地利用图、TM影像、地形图和参与式农村评估、野外踏勘获得的数据基础,进行都市郊区山地区域内景观镶嵌要素与人类福祉间耦合的情景安排,结果表明:未来景观情景强调资源约束和引导经济发展,符合样区以往景观格局演化规律,及今后人口、乡村(城镇)经济和景观行为的变动态势对景观格局调整的需求;情景数量调整注重内涵挖潜,建立了城镇居住用地的扩张与农村居住用地的减少间的消长关系,以改过去以牺牲农用地尤其耕地的扩张方式的再度发生,且适时增加郊区耕地的建园、还林规模和保持未利用地的景观效应发挥;情景空间展布采用分区协调模式,符合样区的微观立地实际,景观状况较好的宽谷、缓坡或低山区注重景观效应的保护和自然恢复,较健康的轻度干扰区或不健康的重度扰动区实行景观格局保护下的重建,而陡坡或裸土(岩)区诉诸于不发展才是最大发展的景观效应策略;都市郊区的山地景观规划必须通过对过去景观格局演化的辨识,做到协调不同利益主体间的矛盾冲突。研究符合山地都市郊区开放空间的产业-景观-用途间协调战略需求的多视角理解,有助于丰富统筹城乡格局下人们对都市郊区产业-景观间耦合镶嵌关系的认识。 相似文献

Interactions between protected areas and their surroundings in human-dominated tropical landscapes 总被引:2,自引:0,他引:2
Protected areas (PAs) often depend on landscapes surrounding them to maintain flows of organisms, water, nutrients, and energy. Park managers have little authority over the surrounding landscape although land use change and infrastructure development can have major impacts on the integrity of a PA. The need for scientifically-based regional-scale land use planning around protected areas is acute in human-dominated landscapes to balance conservation goals with livelihood needs for fuelwood, fodder, and other ecosystem services. As a first step, we propose the designation of a “zone of interaction” (ZOI) around PAs that encompasses hydrologic, ecological, and socioeconomic interactions between a PA and the surrounding landscape. We illustrate the concept by delineating the ZOI in three Indian PAs - Kanha, Ranthambore, and Nagarahole - using remote sensing, population census, and field data. The ZOI in Ranthambore is three times the size of the park and is largely defined by the socioeconomic interactions with surrounding villages. Ranthambore is located in headwaters and wildlife corridors are largely severed. In Nagarahole, the ZOI is more than seven times larger than the park and includes upstream watershed and elephant corridors. Kanha’s ZOI is approximately four times larger than the park and is mostly defined by contiguous surrounding forest. The three examples highlight the differing extents of ZOIs when applying equivalent criteria, even though all are located in densely-populated landscapes. Quantitative understanding of which activities (e.g. collection of forest products, grazing, road construction, tourism development) and which locations within the ZOI are most crucial to conservation goals will enable improved land use planning around PAs in human-dominated landscapes. 相似文献

Parks represent spatially and socially heterogeneous conservation units, yet are often assessed and managed using spatially homogeneous approaches. This paper represents an effort to focus on the larger social-ecological landscapes within which protected areas are embedded, to understand why conservation succeeds and fails in different parts of the landscape. In a wildlife sanctuary in the central plains of India (Tadoba Andhari Tiger Reserve), we address: (i) how people living within and immediately outside a park differentially impact its resources and (ii) how the park differentially impacts communities living within. Using forest plots, satellite imagery and interviews, we evaluate park conservation by assessing plant diversity, land cover change, forest fragmentation, and attitudes of local communities towards conservation. We find that interior villages have a negative impact on regeneration, but there is a decline in tree species diversity, and increased forest cover change and fragmentation at the park periphery. Interior villages suffer greatly from crop and livestock depredations by wildlife and consider park rules to be unfairly devised. Yet, they affirm the importance of the park for conservation, and are willing to work with park authorities for stricter protection. Park authorities largely focus on resettlement of interior villages, when they should also pay attention to protecting the peripheral areas of the park from severe degradation by surrounding villages. In summary, we find that different parts of the park landscape face different conservation challenges. Taking into account spatial variations in the factors influencing conservation can greatly benefit the management of protected areas. 相似文献
