生态城市的绿地系统建设

The Building of Eco-cities' Greenbelt System

介绍城市绿化具有的降温增湿、碳氧平衡、净化空气、减弱噪音、美化环境等生态环境效应.分析我国城市绿化目前存在着的城市规划不科学、不全面,园林绿地数量少,质量差,布局不合理等问题,藉此提出了制定绿地空间布局规划与城市生物保护规划,奠定以林为底色的城市环境,大力推进城郊绿化,发展生态旅游,提高城市绿地率等城市绿地系统建设措施.

The paper introduces the effects of ecological environment of urban greenbelts such as regulating temperature and increasing humidity, carbonoxygen balance, purifying the air, reducing noises, beatifying environment and so on. However, it also analyzes the issues in urban greenbelt in our country including unscientific and unilateral urban planning, little quantity and poor quality of garden afforestation area, irrational layout. Thus, it proposes some measures for greenbelt system construction, for instance, to formulate spatial layout plan and urban biological conservation plan, to achieve urban environment based on the background of the forest, to greatly push forward countryside afforestation, to develop eco-tourism, to increase urban afforestation rate and etc.
