We affectionately call it ecological carpet. Half intensive green roof systemsHalf intensive green roofs, is between the open type of roof greening and intensive between a form of green roof garden, plant selection bees plex, result is more beautiful, also it has the characteristics as follows:1 Maintenance on a regular basis2 Irrigation on a regular basis3 From the lawn greening roof greening to shrubs4 The overall height 12 ~ 25 cm5 Weight is 120 ~ 250 kg/m2Half intensive between natural wild and artificial carve in the roof garden, very natural, low shrubs and flower color bination, but due to the increase in weight system, designer can add more design concept, design more freedom, some artificial landscape also can get a good show.

Roof greening system is also installed on the sidewalk, driveway, recreation area, and the pond. In China intensive green roofs, green areas are often separated from each other. Irrigation efficiency is very low, which makes the late maintenance difficulties, when designers design a hindrance, because they had to consider drain in what position.In Germany, underground parking lot is also seen as roof greening, roof greening for the use of technology is similar. Underground parking garage roof greening in China, but need at least 3 m turns the soil to be recognized as green. 3 m apparently turns the soil is a waste of money and natural resources. The proportion of the original soil of about t/m3, that is to say, if the thickness of overburden soil reaches 3 m, turns the soil load of about t/m3. As a result, the main structure will need a lot of steel and concrete. Not only cost is higher, developers also lost a whole floor space for development. China39。 the birds can also find a habitat. Is full of roof garden city is established suitable for small animals to survive in cities the nature.(4) Reduce the concentration of dust and smokeRoof garden to help filter the dust and smoke particles from the air and rain in the absorption of harmful substances, and its removal from the soil.⑸ could prolong the service life of roofRoof garden protection waterproof layer is not affected by climate, ova and other damage, which greatly extend
