Using concrete land as contrast, an experiment was conducted to synchronously observe land temperature, the highest and lowest temperatures, radiant heat, noises, content of atmosphere dusts at five typical greenbelts in Yichang. The result shows that the effect of green entity in cities has close relationship with its spatial structure and volume. The greenbelt with arbor-shrub-grass vertical structure has the best environmental effect, while the environmental effect of grassland with simple structure and less...

Using concrete land as contrast, an experiment was conducted to synchronously observe land temperature, the highest and lowest temperatures, radiant heat, noises, content of atmosphere dusts at five typical greenbelts in Yichang. The result shows that the effect of green entity in cities has close relationship with its spatial structure and volume. The greenbelt with arbor-shrub-grass vertical structure has the best environmental effect, while the environmental effect of grassland with simple structure and less green entity is relatively weak.

选取宜昌市 5个具典型代表性的绿地类型 ,以水泥垫面作为对照 ,同步监测了包括地表温度、最高最低气温、辐射热、噪音、大气粉尘含量等环境指标。研究结果表明 :城市绿地类型环境效应与其空间结构、绿量大小有密切关系 ,具乔、灌、草垂直结构的绿地类型环境效应最佳 ,而结构单一、绿量含量小的草坪类型对环境质量改善程度有限 ,环境效应相对较差。

The trees and grass species of urban forest in Yan'an were investigated and evaluated,and the result show that there are 113 species,35 families of plant in the urban forest which can't satisfy the diversity in plants.The ratio of arbor,shrub and grass in the urban forest isn't reasonable,and the visual effect of the city park is regarded as the important thing,neglecting the function of the city park in improving the eco-environment.Therefore suggestions are put forward.

延安市城市森林树种草种调查和分析表明,延安市城市林业栽植树(草)种少,共39科113种,选择余地小,不能满足城市绿地类型多样性和植物多样性的要求,乔、灌、草配置比例不合理,城区园林注重视觉效果,忽视改善环境质量的生态功能,对此提出了建议。

Urban green space can be defined as outdoor places with significant amounts of vegetation and mainly exists as semi-natural areas. It has important ecological and social functions,including maintaining biodiversity,absorbing rainwater and pollutants,mitigating urban heat island effects, providing recreation venues,reducing work-related stress,and increasing property values.With social development,people pay much more attention to the living standard in the urban area.Urban green space becomes an important indicator.Analysis...

Urban green space can be defined as outdoor places with significant amounts of vegetation and mainly exists as semi-natural areas. It has important ecological and social functions,including maintaining biodiversity,absorbing rainwater and pollutants,mitigating urban heat island effects, providing recreation venues,reducing work-related stress,and increasing property values.With social development,people pay much more attention to the living standard in the urban area.Urban green space becomes an important indicator.Analysis of green space pattern is the basis to optimize urban planning in the future.In china,after the Reform and Open Policy and the Urban Land Reform initiated in 1980s,Chinese cites are facing a rapid urban expansion and redevelopment.This rapid urbanization profoundly transformed the spatial pattern of urban area,obviously,including the green space.The government attempts to plan green space to adapt the urban development,which requires an understanding of the process of green space change.This has been done since 1980s.But most of the cities have implemented green planning since 1990s.Quantification of green space patterns is a prerequisite to the understanding of green space changes,and is essential for monitoring and assessing green space functions.This paper presents a new method for quantifying and capturing changes in green space patterns, through a case study of Ji′nan city which carried out five phases of greening work after the establishment of the "Great Changes in Five Years" in 1997,resulting in tremendous change of urban spatial pattern,especially the green space,during 1989-2004.Supported by GIS and remote sensing,we quantified the local green space with the "moving window" technique(using FRAGSTATS),and a gradient analysis by sampling from the urban center to the fringe.Results demonstrated that:(1) Based on urban green space type map and moving window technique,gradient maps of different landscape metrics in each local area and the sampling analysis from urban center to the fringe in eight directions could precisely quantify the significantly altered green space pattern;(2) Changes of green space pattern in spatio-temporal gradient could obviously reflect the effects of urbanization and the implementation of governmental policy;(3) Using moving window technique,landscape metrics could be quantified in each local area;(4) Compared with quantifying metrics in the entire landscape,partial quantification of landscape pattern could link pattern and processes more effectively,and establish an important basis for subsequent analysis of ecological and socioeconomic functions of green spaces.

随着社会经济的发展,人们越来越关注生活质量,而具有重要生态和社会经济功能的城市绿地是反映一个城市生活质量的重要指标。因此,城市绿地空间格局的定量研究就显得尤为重要。以济南市作为研究区,以RS和G IS为技术手段,采用梯度分析和景观指标相结合的方法,在8个方向上从市中心到边缘取样,对研究区1989、1996、2004年的城市绿地空间格局及其变化进行了定量分析。研究结果表明:(1)基于城市绿地类型图、运用移动窗口所得到的梯度分析结果能够准确的表达城市绿地空间格局及其动态变化;(2)城市绿地时空梯度的动态变化能够反映城市土地利用空间结构及政府政策的影响;(3)梯度分析方法能够实现景观指标的空间化与可视化;(4)局部区域上的景观指标量化与整个景观水平上的量化相比,能够更好的连接景观格局与过程,对进一步分析城市绿地的生态和社会经济功能具有重要意义。
