盘锦红海滩湿地公园设计

城市湿地公园作为维护和修复城市湿地生态环境的主要途径之一,不仅为居民提供丰富的景观和休闲资源,也影响着城市的生存环境,同时还是科普和科研的重要基地。笔者所参与的红海滩湿地公园规划项目在对红海滩原有资源进行保护和整合的基础上,提出水乡田园·湿地慢休闲的设计理念,力求做到设计契合地域文化、彰显红海滩特色,将自然环境与人文景观完美融合,实现旅游经济与湿地保护共赢的目的。     

枯落物与根系对城市土壤改良作用概述

我国各地区土壤研究报告指出,城市土壤质量不断下降,导致地上植物生长受阻,对环境的净化功能减弱,环境质量下降,危害公民的身心健康,严重时甚至影响整个国家和社会的正常秩序。为了避免这一现象的严峻化,初期解决方案是运用化学方法-土壤改良剂来改良土壤,后期研究发现枯落物和根系对土壤的理化性质也具有积极作用,前后对比可知:枯落物和根系对土壤的改良作用具有持久性,对土壤质量的危害最小。本文在前人研究的基础上总结归纳枯落物和林木根系改良土壤的原因,并深入剖析其中的影响,探讨改良城市土壤的可行性方法,探索出改良土壤的最佳方案,以保证我国城市森林土壤质量的优良。     

探析非物质文化遗产如何应用于城市园林景观建设

城市园林景观是人类智慧的结晶,是地域文化特色的直接反映。非物质文化遗产不仅是记录历史文化的活化石,也是城市特色园林景观建设的文化资源。在城市园林景观中合理有效地提取与应用非物质文化遗产,不仅有利于城市地域文化的延续,还可提升城市园林景观的文化品位。     

广州部分公园的冷岛效应及影响因子的初步研究

结合植被种类和群落结构调查,对广州四个城市公园绿地的温湿度进行自动监测,每1小时一次,连续监测30天,并采用PCA排序法分析广州市公园的"冷岛"效应与植被、公园面积等因子之间的相关性。结果表明:白天公园气温降低值和相对湿度增加值大小排序一致,黑夜的排序则与之相反。白天的月气温降低与公园面积、水体面积和乔木平均胸径呈正相关;月气温降低与乔木密度呈正相关;月、白天、黑夜相对湿度增加与乔木平均树高、乔木平均胸径、水体面积呈正相关。最终得出结论,广州市的城市公园具有显著的降温增湿效应,且日间降温增湿的幅度大于夜间。     

Establishing a spatial grouping base for surface soil properties along urban–rural gradient—A case study in Nanjing,China

Conventional classification systems based on vegetation and land use are frequently used to characterize or describe urban soils to determine the influence of urbanization on soils. In this study, the sensitivity of different grouping methods in reflecting soil variations along an urban–rural gradient was compared. The objective of this study was to determine the most sensitive grouping system in depicting and explaining variations of soil attributes around an urban area. Grouping methods, including urban–rural division, in situ vegetation type, land use types in different scales and numerical clustering, were compared for both single soil attributes and “soil set” defined by multiple variables. The result shows urbanization has a strong impact on many soil properties, especially that of gravel content, sand content, pH, phosphorus and soil compaction. In terms of the variations of soil attributes, in situ vegetation type is the most sensitive in comparison with local land use types and district-viewed land use types. In other words, soil properties in this study are not sensitive to coarser spatial resolution. Therefore, it's hard to interpret the spatial variation of urban soil by regular methods using natural soil-landscape paradigm. Furthermore, vegetation would best proxy the delineation of single attribute of urban soils. Numerical clusters effectively reflect the land use types and their change during urbanization. All clusters were interpreted as different sets with practical meanings: soil in abandoned greenbelt, soil in ill-managed greenbelt, soil in new vegetable land, extreme urban conditioned soil, soil in well-managed greenbelt, soil in highly mellowed vegetable land, soil in common urban–peri-urban greenbelt and weak-urban-impacted soil. They can be used as bases for soil regionalization in urban and peri-urban environment.
