城市绿地率

建筑环境绿化还为提高城市绿地率提供了发展空间；

Building greening provides more developing space for heightening green ratio of the city .

对不同太阳高度角和太阳方位角下建筑外表面太阳辐射吸收情况及其增热效应进行了探讨，提出了加入建筑物外表面面积的新型城市绿地率计算公式。

The solar radiation absorption quantity for the building exterior surface under different sun elevation an - gle and sun azimuth and its heat effects are discussed . A new formula for the calculation of urban green land rate is given , which involved the exterior surface of buildings .

并进行图像的监督分类、绿地的提取，由此得出重庆市都市区的绿地状况特征：城市总体绿地率低，绿地分布不均，长江两岸的覆盖率低。

The greenland characteristics of Chongqing city are concluded as low greenland rate of city on the whole , unbalanced greenland distribution , low forest coverage on both sides of Changjiang river .

南京市的城市森林绿地覆盖率至少要达到45%，面积为29.322×10~4ha才可以满足城市环境生态功能的正常运转。

The percent 45 ( equal area 29.322 X 104 ha ) of the urban forest and green space cover rate is proper for Nanjing .

通过对常德园林现状按照绿地类型进行分类统计得出，到2007年底，常德市城市建成区绿地率已经达到35%。

Reach , arrive at the end of 2007 by the fact that current situation classifies and counts to Chang De City gardens according to that the greenbelt type is in progress , the Chang De City city establishes area greenbelt rates already reaching 35 % .

除维也纳外，各城市居民区绿地覆盖率介于以上两功能区之间，但往往低于城市整体水平。

Except for Vienna , PLAND value of residential area is between the two mentioned areas above and is always lower than the whole city level .
