Ecological Planning and Design of Urban Green Space System of Sanya City

The construction of International Tourism Island has accelerated the development of Sanya City. The population aggregation and the external extension of urban area have brought a lot of negative effects, such as discontinuities of green space matrix, dysfunction of green wedge permeation, deficiency of eco-corridor, structural imbalance of green space system and so on. The overall layout of Green space system known as One Belt Three Bays, One Core Six Towns, Two Axes Three Wedges, Two Net Synchronous-construction strengthens the eco-connection among different groups and green space in central area of the city, and realizes the collaborative construction of both resource corridor and landscape corridor. The eco-layout of green core, green corridor and green patch helps keep the integrity of large vegetation patches, enhances the eco-connection of different types of green space and improves finger-shaped network of urban green space. The most efficient way to promote the circulation of urban ecosystem and the positive development of Sanya City is to plan multilevel and three-dimensional eco-space structure and maximize ecological benefits of green space system.     

Images of Green Landscapes in Huadu District,Guangzhou City

Urban landscape, as an important part of the overall landscape or the overall image of the city, is of great significance in highlighting city features, building green cities, and improving city image, so image of green spaces has become one of the key construction objectives for many cities. Taking Huadu District in Guangzhou City for example, urban green landscape pattern was analyzed from the level of region and district, according to the landscape ecology. The results showed that local green landscapes had many problems such as unreasonable structure, high fragmentation, unbalanced distribution of green space types, poor corridor networks etc.. In view of these problems, countermeasures for improving green landscape images in Huadu District were proposed.     

城市防灾避险绿地系统的构建

乌鲁木齐市园林树种的调查，规划，评价

摘要 本文对乌鲁木齐市的园林树种和绿化现状进行了系统的调查和研究,依据园林绿地国家《城市绿地分类标准CJJ/T85-2002》,对主要的绿地类型中现有树种进行了调查、统计、分析、评价,应用城市生态学,园林美学,城市规划等学科的相关理论,根据乌鲁木齐市城市的生态特点和植被分布规律,以及乌鲁木齐市作为国家西部内陆地区集政治、经济、文化中心,交通枢纽于一身现代工业城市性质,对城市园林绿化树种进行了总体规划,为园林植物景观的优化提供了理论依据。 根据调查统计,乌鲁木齐市木本植物共有132种,其中常绿树种17种,落叶树种115种,常绿树种与落叶树种的比例为 1：6.76;从树种比例来看反映出乌鲁木齐市地属内陆干旱地区,树种单调且分布不均。 今后乌鲁木齐园林树种规划的原则是：（1）生态优先原则;（2）特色与创新原则;（3）适地适树原则;（4）可持续发展原则; 在此基础上确定了乌鲁木齐市城市绿化的基调树种、骨干树种,并对城市的生态防护林、景观路、行道树、公共绿地、垂直绿化等应用的树种进行了具体的规划。

城市绿地系统社会服务功能及其评价研究综述

城市绿地系统社会服务功能所具有的重要价值已在世界范围内引起了人们的普遍关注,有关城市绿地系统社会服务功能及其评价的研究也取得了较大的进展。但通过文献综述发现,这些研究对城市绿地系统社会服务功能与城市绿地的规划、建设、保护和管理之间的相互关系探究极少且深度不够,使得这些研究的实践意义不大。而在有关城市绿地系统社会服务功能评价的研究上,也存在着诸如评价指标少且未形成体系、研究范围较窄、研究的深度和广度不够等不足,以致不能真实、综合地反映出城市绿地系统多元的社会服务功能。为此,为了全面、客观地反映出城市绿地系统社会服务功能所具有的价值,应坚持综合性、层次性、独立性,可操作性、易获得性等原则,并构建定性与定量相结合的指标体系。

Reduction of Urban Green Space on Stormwater Runoff Pollutant

In order to explore the effectiveness and feasibility of urban green space on regulating urban rainfall-runoff pollution, the simulated test of soil column was adopted to study the effects of vegetation cover, runoff pollution concentration, soil depth and groundwater, and hydraulic loading rate and residence time on reducing the pollutants by green space. The results indicate that green space has a good and stable ability to reduce three stormwater runoff pollution concentrations, which COD are 68, 137 and 550 mg/L, TN are 3.01, 7.51 and 30.06 mg/L, TP are 0.29, 0.69 and 2.73 mg/L, and NH+4 are 0.44, 1.61 and 2.19 mg/L respectively, with 3.5, 3.0 and 2.5 cm/h hydraulic loading rate respectively and continuous inflow 1h. The pollution reduction rates of COD, TN, TP and NH+4 by green space reach to 41.52%, 78.96% and 84.68%, 50.21%, 70.23% and 60.91%, 73.18%, 95.88% and 94.99%, and 62.72%, 55.16% and 69.98% respectively. Restricted by the soil reaeration capacity and hydraulic retention time, the effect of vegetation cover on pollution reduction rates of COD and TN is not significant. With the rainfall-runoff pollution concentration increased, the pollutant reduction rate of green space shows a gradually increasing trend. The reduction of green space on the stormwater runoff pollution mainly occurs in the soil depth of 35~65 cm. The reduction rate of each pollutant for the low, medium and high pollution concentration level decrease with the hydraulic loading rate increased.

On Green Lighting Planning and Design of the City

The energy-conserving environmental protection and the culture characteristic protection are two themes to the sustainable development of modern city,and the green lighting project is an important condition to ensure sustainable development of the city.But now,in some lighting projects the energy consumption and economy power capability were ignored;some design tactics are identical and in the green lighting projects the whole lighting of the city was not considered,which cause the crisis of losing the city characteristic.This paper proposes the green view of city lighting planning,and points out that the energy conservation,environmental protection,economic feasibility and culture characteristic must be considered synthetically in the city green lighting planning and design to guarantee sustainable development of the city.
