城市滨水带是水生动植物栖息生存的重要廊道,是生态宜居城市建设的重点。然而城市中大量渠化的硬质河道阻碍了河道与河岸带生态系统的水、气循环,造成城市滨水带生物多样性减少,生态系统功能逐渐退化。本文基于人工诱导自组织生态修复技术的原理,采用水生态功能性设计及自然生境改善技术,对城市滨水带驳岸形态、驳岸材料、植物群落进行自组织设计,从水体生态系统的动态演替角度进行优化与实施,对水岸生态系统自组织过程进行诱导,使城市滨水带水体、植物、动物等要素形成自我修复、良性循环的生态系统,从而实现城市滨水带生境效能和稳定性的改善。 相似文献

在大力推进生态建设和水环境治理的新时代下,黑臭水体治理中生态修复仍然存在着河道护坡硬化现象以及对生态修复技术认识不足等问题.本文从护岸、缓冲区和河道本身三方面归纳总结了河道生态修复技术.护岸生态修复技术包括植被护坡、人工材料复合植被护坡、多孔材料护坡、生态石笼护坡等;缓冲区生态修复技术有人工湿地和生态塘-人工湿地技术;河道本身生态修复技术概括为物理修复、化学修复和生物-生态修复技术.通过对河道生态修复技术的分类阐述,以期为今后的河道生态修复研究与实践工作的开展提供参考. 相似文献

<正>市河道长期受城市发展带来的工业污水乱排乱放、农业过量使用各种药物产生的附加污染排放以及城市污水无节制对河道排放等积累性污染,最终让河道水体恶臭难闻。因此,治理河道污染要做到标本兼治,不仅要治理河道污染,同时要处理好后期河道清淤产生的大量淤泥再次对环境产生二次污染。本文将研究各种淤泥固化措施和各种回收途径再利用在城市黑臭水体淤泥处置上的应用。城市黑臭水体内源治理首先要进行截污和清淤,这样才能从根本上彻底治理城市黑臭水体给环境带来的污染,然后再通过后期漂浮湿地、湖滨湿地、生态驳岸以及强化微生物等技术进一步让城市河道水体符合国家环保地表水景观用水标准。清淤 相似文献

Based on the generalized landscape perspective, regional connotation of urban river landscape is expanded. The area connotation of urban river landscape is expanded based on the generalized landscape perspective. In addition to natural and functional attributes, river landscape should be regarded as a regional space element based on heterogeneous space scale. First, as for research method system, the space research models(including ecological footprint, space planning, and landscape pattern index, etc.) coupled with different angle scales and interdisciplinary theory, are utilized to study different correlations and results formed by urban river landscape elements and other regional space elements from the perspective of the regional ecological space, and the overall development goal of the urban river landscape pattern based on the goals of the regional ecological space planning is obtained. Second, the oriented urban river landscape planning and the "M" type close-tonature design strategy are evaluated through the city function zoning orientation and micro-scale urban river landscape pattern index. The research realizes the compatibility of overall goals in terms of the regional ecology, the development of urban functional areas, and the river landscape planning, without losing micro difference and maneuverability based on the urban river landscape planning and design oriented strategy, which innovates the new approach of urban river landscape planning and design with sustainable and balanced development of regional resources, multi-scale, and multiple objectives. 相似文献

To balance the ecological–aesthetic relationship in urban river ecological restoration, the research analyzed the ecological aesthetics performance of related practice. By defining „ecological aesthetic preference” and establishing a triple framework of ecological aesthetic preference on urban riverfronts, the research summarized three major factors that impact ecological aesthetic preference. With the Urban River Survey method, 24 typical river section samples in Kunshan, Jiangsu Province were selected. Through correlation analysis and optimal scaling regression model, relevant characteristics and influencing mechanisms were analyzed. The results include that: 1) Individuals’ ecological awareness and knowledge level has the most significant impact, followed by ecological factor characteristics of riverfronts and individuals’ social–cultural characteristics; 2) The respondents having higher cognition on ecosystem services show a stronger aesthetic preference for urban riverfronts; and 3) Vegetation characteristics impact ecological aesthetic preference more than material and physical habitat characteristics, and different combinations would lead to various overall benefits of urban riverfronts. Therefore, urban river ecological restoration should better integrate ecological values and aesthetic values by flexibly combining spatial elements, meanwhile fully consider social demands for urban riverfronts, to promote people’s ecological awareness and knowledge level and provide them with better landscape perception of ecosystem services. 相似文献
