“南谯模式”绿了荒山富农家

滁州市南谯区,地理地貌有个典型的特征,就是境内石灰岩、安山岩富集,近两万亩的石灰岩、安山岩构成了一座座石质山遍布南谯各地,给当地的造林绿化带来了极大的困难。近年来,南谯区在试点林改的过程中,摸索了一套行之有效的新模     

京城处处有花园——首都花园式单位剪影

在北京,无论是高楼大厦的小区,还是大的机关厂区周围,无论是道路两侧,还是大小公园,到处是绿树和鲜花,把城市装扮得自然美丽。北京的业内人士说: 到2008年之前,北京三季有花,四季常绿的花园式单位将达5258个,这些单位的绿化带将超过70%。那时, 一大批不拘一格的花园景观将展现在人们的面前。海特花园的花园住宅走进石景山区的海特花园住宅小区,立即被这里     

洱海水资源环境及可持续利用对策

自古以“玉洱”闻名天下的洱海为云南第二大高原湖泊,面积250km^2。由于企业不达标排污、面源污染、湖滨带大面积丧失、盲目引进外来物种等原因,致使洱海水环境日益恶化,据此提出了水资源可持续利用对策。     

Soil quality index as a tool for Scots pine （Pinus sylvestris） monoculture conversion planning on afforested,reclaimed mine land

In Central Europe,a large portion of post-mining sites were afforested with Scots pine,which is characterized by good adaptability and a tolerance for poor habitat at the beginning of forest ecosystem development.Conversion of monoculture on mine sites into more biodiverse mixed hardwood forests,especially on more fertile deposits,can be an emerging need in this part of Europe in next decades.The ability to classify the forests at these post-mining sites will facilitate proper species selection as well as the management and formation of the developed ecosystem’s stability.This work describes the guidelines that can be followed to assess reclaimed mine soil(RMS)quality,using the mine soil quality index(MSQI)and a classification of developed forest sites as a basis of tree-stand species selection and conversion of pine monocultures.The research was conducted on four post-mining facilities(lignite,hard coal,sulphur,and sand pit mining areas)on different RMS substrates dominant in Central Europe.Soil quality assessment takes into account the following features of the soil:texture soil nutrients(Ca,Mg,K,Na,P);acidity(pH KCl);and Corg-to-Nt ratio in the initial organic horizon.An analysis was conducted of classification systems using the MSQI validation correlation(at p=0.05)with vegetation features affected by succession:aboveground biomass of forest floor and ecological indicators of vascular plants(calculated on the basis of Ellenberg’s(2009)system).Eventually,in the analysed data set,the MSQI ranged from0.270 for soils on quaternary sands to 0.720 for a mix of quaternary loamy sands with neogene clays.Potential forest habitat types and the role of the pine in the next generation of tree stands on different RMS parent rock substrate were proposed.     

城市道路绿化带滴灌技术的应用

针对干旱地区城市道路绿化带灌溉问题，经过多次实际测试，首次总结出了滴灌技术应用于城市道路绿化带灌溉系统中的滴灌系统布置、首部枢纽设计、滴灌设备的选择、控制系统设计及管网水力计算公式。     

基于“海绵城市”理念的下沉式道路绿化带设计

海绵城市理念是建造类似海绵功能的城市,用现代化技术建设人工景观,并将其与城市原有的水文特征相结合,组成新的生态系统,实现对自然界水资源最大程度的循环利用。本文将以下沉式绿化带为例,首先论述了海绵城市以及下沉式城市道路绿化带的基本概念,着重分析了下沉式道路绿化带影响因素,提出了下沉式道路绿化带设计的主要策略,以供相关人员参考。     

龙游县城区绿地系统规划实施的建议与措施

浙江省龙游县城市绿化以建设"生态园林城市"为目标,按照《龙游县城乡绿地系统规划(2006-2020)》确定的"一环二带三区九园"绿地布局结构,城市绿化与山体、水系、广场、道路紧密结合,形成独特的绿地景观,"城在绿中,绿在城中"的格局已基本成型。为更好地做好山、水、绿的文章,实行规划建绿、改造增绿、点上铺绿、线上延绿、面上插绿的办法,

高速公路绿化带建造

一．公路带绿化的特点和功能 1．净化空气首先，绿色植物在光合作用过程中能够吸收二氧化碳，放出氧气，自动调节空气中二氧化碳和氧气平衡，使空气保持新鲜；其次，由于行车的影响，柴、汽油燃烧后排出大量二氧化碳、二氧化硫、氟化物等废气，不仅污染环境，而且直接损害人体健康。而绿色植物如同空气过滤器，能吸收大量的有毒气体，对空气起到净化作用；
